POSITIVE & NEGATIVE INTERACTIONS THROUGH OUT A REGULAR DAY
In my daily interactions I came upon many positive and negative consequences. On an average day on the weekend a few thing I encountered were, taking out the garbage and recycle, eating three full meals, watching TV in my house, going to the pool and taking my dogs out for a walk. Taking out the garbage and doing recycling is a positive consequence because recycling helps the environment by reusing and reducing the waste of plastic and garbage around the Earth. A negative interaction I did was watching TV, by doing this I was waisting electricity that could have been used for something else. I ate all of the food on my plate not having to throw anyway so I would not be waist full. On Saturday I went to the pool to help my brother practice for his National Lifeguarding course, in order to get to the pool my dad had to drive us. When my dad drives us places it causes air pollution leading to the atmosphere, over time enough pollution creates climate change and global warming. We are also waisting fossil fuel we use to run our vehicles. The final thing interaction I made was taking my dogs out for a walk. This interaction is not necessarily a positive nor negative interaction but taking out my dogs made them really happy and I was able to encounter the geosphere within my surroundings.
When I first woke up on a Sunday morning I went downstairs for breakfast. I did not want to be waist full of my food so I decided to have leftovers from the previous night before. Saving food from previous use was a positive consequence but the leftovers I was eating was “take out” Panago pizza. In order to receive the pizza an employee had to travel in a vehicle polluting the air in order for my family to enjoy our Saturday night dinner, this would be a negative interaction. When I went to Maple Ridge aquatic centre I realized how much maintenance pools require. The water tank is always flowing and a lot of chlorine is required to keep the pool safe. Even though pools do not have the same water bacteria as rain, lakes/rivers/oceans but the pool water does come from those areas. Pools have a connection to hydrosphere as the water comes from dense clouds of rain falling into bodies of water.
“recycling turns things into other things which is like MAGIC!”
A few actions I will try to prevent myself from implementing; I am going to try and cut down on screen time, to do this I will create a schedule and I will record the amount of time I have been watching TV if I go over the amount of hours I decide is to much then I will do something helpful towards the environment. Something I might commit to are, growing plants in my front yard or maybe going out for a nice walk to get some exercise. After every meal, whenever I have extra food left over I will refrigerate it and save it for left overs so I will not be waist full. One other alternative I could commit to, if I had extra food on my plate after I was done I would put all of my scrap foods in a green waist bin so my food would not be going in the garbage. A way to help prevent loss of species would to try to consume less red meat. I’m not telling you to become a vegetarian, I really enjoy eating meat. I am only suggesting to decrease your regular portion of red meat because research shows that many animals made of red meat play a huge roll in climate gasses. Animals like cows and bulls produce a large amount of methane gas. My final suggestion to help help concur the Earths pollution problem would be to carpool as often as possible, it doesn’t take much to achieve those small little tasks that actually do make a difference. The reason you may not be seeing improvements with Earths global warming is because not enough people are helping out. I encourage everyone to go out and do something time worth to help keep our planet healthy for longer!
In my eyes the whole point of this assignment was to search for new opportunities that can change your whole life for the better, helping out your own ground to keep clean and safe. This assignment wasn’t only an article that was required to write in order to get a good grade but it was for me to get a better look at my future. In my future I will help the Earth escape from global warming. I know it’s a big goal but I strongly believe if everyone did something as small as picking up someone else’s trash even though it’s not yours, then we can save the planet. We can not do this alone, every one needs to equally commit before we equally destroy our planet Earth.
We started our experience of “Engineering Brightness” half way through December with no idea how important this project was to so many people around the world. To start off our project we contacted Pitt River middle school and schedule a meeting with their leadership class. My group of three consists of Janna, Sabrina and I, we all went in to there school and gave a presentation. The presentation went extremely well and all of the leadership students were enthusiastic about contributing there funds that are made to the Dominican Republic to help illuminate light poverty. Once winter break was over we started emailing back and forth between students and teachers at Pitt River and we scheduled another date to come in. A few weeks ago we came in for our second visit where all the students were very appreciative and exited for our appearance. We went over a few fundraising ideas and agreed to hold a bake sale from January 31 – February 3. My group and I have made posters that have been put up all around the halls at Pitt, and a few posters will be getting put up in the community hopefully in local restaurants, Starbucks and other shops. Pitt River will be hosting the bake sale and all funds will be going towards buying supplies to make lights to support the other groups in my class who will be doing so. While we were at Pitt River during our second visit, we also discussed doing school visits to local elementary schools. It looks like we will be visiting Kilmer, Central, and Castle Park elementary school sometime next week. At these three elementary schools we will all be giving presentations to the students so they know why we are fundraising and what engineering brightness is about. After our school visits, all five of our schools (Riverside Secondary, Pitt River middle, Central, Castle Park and Kilmore elementary school) we be doing individual fundraisers for the Dominican republic. Pitt River will be continuing on fundraisers for the rest of the school year and at the end they will transfer all the money earned to Riverside so we can purchase all the supplies needed. We are all very exited about the journey we have been going through and have had great enjoyment helping others in need.
Through out this learning experience I have gained the knowledge of how fortunate we are to have all of this fantastic technology. We take things for granted here in Canada because we have never experienced not having something so useful. In the Dominican Republic, Children come home from school to an empty dark house with no cable or any electricity. The life style from Canada to the Dominican are so different. When ever our power goes out we get exited and think yay no school, but When the Dominicans power goes out its not anything exiting, its just an everyday issue they have to deal with. Many children are unable to go to school because it is to cost effective so they are forced to work in the cain fields and do manual labor. The way they are treated is so different form how we are treated, I hardly know one person my age who is 14 and has a part time job. We come home from school and make up excuses of why we didn’t do our homework when kids in the Dominican don’t even have light to do any work at home. We shouldn’t be complaining, we should be thankful for receiving the best education in the world. There are so may thing I have learnt form engineering brightness, such as confidence. Presenting in front of others about this situation has given me confidence on being able to talk in front of different crowds of people.
Over all I am really pleased with how this whole experience has been going. I was able to reconnect with my old classmates while I was at Pitt, and I was able to help a different country half way around the world. I really feel lucky to have had this experience and I am happy that we were able to inform other schools to continue on the fundraising. I really enjoyed having the experience of multiple Skype calls with the Dominican Republic and New Brunswick. Even though we were talking about a serious topic, the Skype calls were fun to check in on them to see how they were doing and to hear what their plans are, it was really special.
Asexual reproduction is when the offspring is a genetic clone of the single parent. If the parent has a mutation the mutation is guaranteed to be passed down to the offspring. Some examples of animals that are able to create an offspring through asexual reproduction are cloning wasps, captive sharks, komodo dragons, whiptail lizards and marbled crab. In asexual reproduction their are four different methods for reproducing. They are Binary fission, fission, budding and Fragmentation. In asexual reproduction during the process of binary fission, genetic material (DNA) gets duplicated by an organism in the body. Later the DNA split into two parts, which is called cytokinesis. Binary fission is the primary of the reproduction process. Budding is another way of asexual reproduction. In some species, buds are able to be produced in almost any part of the body. Overtime the buds develop into an organism and duplicate the parent cell. Fragmentation is when a new organism grows from a fragment of the parent. All fragments eventually turn into a fully grown individual.
Sexual reproduction is When an offspring is created through a mix of two parents each with 23 chromosmes. The 46 chromosomes get passed down from the parents to the offspring creating the DNA for the child. The offspring gets inherited genes from the parents with the process of fertilization. There are two types of fertilization, internal and external. For species that use internal fertilization the purpose is so the mother can protect the egg inside of her. The extra protection gives a better chance for the eggs survival because the mom will be supplying everything the egg needs. An example of species that produce internally are mammels. External fertilization occurs mostly in water or areas where it is very wet. When external fertilization occurs often multiple offspring are created. Sometimes the offspring will not make it into adult hood because there are risks for being fertilized in an outdoor climate. A couple of examples of species that produce externally are fish and amphibians.
Pro’s and Con’s of asexual and sexual reproduction.
Pros of sexual reproduction: With sexual reproduction there are two parents involved meaning the offspring will be unique and not exactly the same as either parents. Also the offspring has a chance in not receiving the same decease of the parent because the offspring is not a genetic clone of a single parent. Unlike asexual reproduction it is possible for a new species to be discovered during this process.
Cons of sexual reproduction: Only half the population (females) are able to reproduce and they must have a mate to do so. There has to be two parents to create an offspring and it takes nine months for the child to be born. Within those nine months something can happen to create a miss carriage and there is no guarantee that the baby will be born.
Pros of asexual reproduction: Only one parent is needed to create an offspring. There is a high chance that the offspring will be created successfully. Fertilization is not necessary and the offspring will be the exact same species and will have identical characteristics as its parent. Asexual reproduction includes fewer steps then sexual reproduction making it more reliable.
Cons of sexual reproduction: The offspring would be a genetic clone of its parent meaning the parents mutations or diseases will for sure be passed down to the offspring. There is almost no chance at all for evaluation taking place for the offspring. A disadvantage for plants using the vegetation method is that they are all likely to be effected by the same disease and they can be harmed by the same conditions.
Meiosis is a form of cell division that produces useful cells such as sperm and egg cells, plant and fungal spores. All cells originate from other cells through a mechanism called cell division. The parent cell splits into two or more cells called daughter cells. Through cell division we are able to pass down genetic information from generation to generation. The daughter cells that meioses produces are only half of the amount a parent cell has. The mother and father chromosomes exchange bits to create unique chromosomes for the daughter cell. The first step of meiosis starts with chromosomes duplicating. Then the cells go through two rounds of division with the final product of four daughters cells, each with half the amount of chromosomes from the parent cell.
In Meiosis I the sister chromatids blend together at the centromere and form the shape “X “, they become dense compacted structures that are now visible underneath a microscope. Prophase I sister chromatids from the mothers set of chromosomes
pair together with their identical protective chromosomes. The maternal and paternal chromatids exchange pieces of DNA and then recombine to new genetic variations. In a male human, even though the sex chromosomes (X and Y) are not alike they still exchange DNA and pair together. At the end of prophase I, the nuclear membrane breaks down. Metaphase I emerging from a structure called the centriole, meiotic fibres and a long chain of proteins are positioned at either end of the cell. The meiotic spindle hooks onto the fused sister chromatids. At the end of metaphase I, the sister chromatids are at their centromeres and line up in the middle of the cell. Anaphase I the spindle fibres start to separate, pulling sister chromatids with them. The X-shapped
chromosomes start to split and half of each chromosome ends up on opposite sides of the cell. Telophase I the sister chromatids reach the ends of the cell as it splits into two. The result of Meiosis I ends with two daughter cells with each containing a set of fused sister chromatids. The two daughter cells from Meiosis I transition in to Meiosis II where there is no more chromosomes being duplicated.
In Meioses II by the end of the process the number of chromosome will not have changed even though by the end of meiosis II there will be four daughter cells and not two. Prophase II meiotic spindles start to form again after the nuclear membrane starts to break apart. Metaphase II the meiotic spindles hook onto the centromere of the sister chromatids and they all line up in the centre of the cell. Anaphase II the spindle fibres start to break away and sister chromatids are pulled apart. The individual chromosomes begin to separate on to each end of the cell. Telophase II once the chromosomes reach opposite ends of the cell the nuclear membrane forms again and the cell body splits into two. There are now four daughter cells each with the same amount of chromosomes in them. Every single one of the chromosomes are unique because they came from maternal and paternal chromosomes, originally from the parent cell.
Mitosis is similar to Meiosis where the organisms generate new cells through cell division. In this process, the parent cell will divide and produce an identical daughter cell. In Mitosis a cell isolates its duplicated DNA, finally dividing its nucleus into two. Mitosis is divided into four stages (P-MAT), these four stages are also seen in the second half of Meiosis.
Prophase the chromosomes that have been duplicated are combined and can be seen by the sister chromatids. The mitotic spindle and a narrow chain of protein moves to a structure called centrioles at either ends of the cell. Metaphase at the centromere after the nuclear membrane dissolves, the mitotic spindle hooks onto the sister chromatids. The mitotic spindle is now able to move the chromosomes in the cell. At the end of Metaphase all chromosomes are alined in the centre of the cell. Anaphase the mitotic spindle leaves and pulls the sister chromatids apart, leading them to move to opposite ends of the cell. Telophase the chromosomes go to either end of the cell, after cytokinesis occurs when the nuclear membrane reforms and the cell body splits into two. At the end of Mitosis, a cell produces a genetically identical daughter cell.
Mitosis and Meiosis compare and contrast
Compare: Mitosis and Meiosis both use the form of cell division and they both are used for reproducing. They both share many steps of their own process going through P-MAT. Meiosis and mitosis both produce new cells through dividing their parent cell and creating new daughter cells.
Contrast: The purpose of Mitosis is for asexual reproduction, growth and cell regeneration. At the end of the whole mitosis process it ends with a single nuclear division resulting with two nuclei that dived into two new daughter cells. Th nuclei from mitotic division from mitosis are genetically identical from the original nucleus. In mitosis the daughter cells have the same number of chromosomes as the parent cell.
The purpose of Meiosis is sexual reproduction and gametes. At the end of the entire meiosis process there are two nuclear divisions which leads to having four new daughter cells in the end. The nuclei from meiosis are not genetically identical because crossing over occurred and only the nuclei contain one set of chromosomes. In meiosis the daughter cells have half the amount of chromosomes the parent cell has.
How organisms grow
Matching + Methods of fertilization
The process of mating includes gametes. Gametes is a male or female germ cell that can be united with the opposite sex during sexual reproduction. For animals it is very different then from humans, many animals have matting seasons during certain times of the year to make sure the environmental conditions will be okay for their offspring. For humans we do not have a specific matting season because the weather conditions do not effect the offspring. The two main types of fertilization are internal where the sperm and egg unite inside the parents body, and external where the sperm and egg unite outside of the parents bodies. Sperm cells are deposited inside the females body were they meet an egg cell. The conditions that need to be met to be able to have the fertilized egg go through cell division are, there must be enough nutrients for the dividing embryo. For the proteins and enzymes to function properly during chemical reaction in developing embryo, the temperature must be warm enough. There must be sufficient moisture so the embryo does not dry out. Embryo must be protected from predators and from other environmental factors such as ultra violet radiation.
The Transfer From Pollen to Plant for Fertilization
Pollen is a substance that is powdery and typically yellow. It is discharged from a plant to a clone. Fertilizing plants involving the fission of male and female gametes. Pollen can be transferred by people, bees, butterflies, moths, flies, hummingbirds and wind. The embryo develops in the female part. A few disadvantages on how pollen is transferred are the birds are less immune to disease. The variability and hence adaptability to change the environment has been reduced. New useful characters are not frequently being introduced. Some advantages on how pollen is transferred are self pollination eliminates some bad inactive characters. The plant does not need to produce large number of pollen grains. Flowers do not develop devices for attracting insect pollinators.
Embryonic development is when the embryo begins to form and starts to develop. For humans, during the first two months after fertilization the embryonic development takes place. Once fertilization is over zygote begins the process of mitosis and a series of rapid cell division occurs. Embryonic development goes through four stages which are morula stage, the blastula stage, the gastrula stage and the neurula stage. The process of embryonic development is stem cells divide, migrate,and specialize. In the early stages of development, the inner cells mass start to form. The inner cells mass are the cells that produce tissues of the body. During gastrulation later in the development, the three germ layers form. After this stage it is common that most cells become more restricted in the types of cells they can produce.
The stage that occurs before the fetus begins to develop is embryo development. In the first stage of the first trimester, organisms start to develop. The first trimester takes eight weeks of fertilizing the egg with the offspring to be about 28 grams and 9cm long. During the second trimester the offspring grows in the fetus for about 12-16 weeks with the weight of the offspring to be about 650g, and 35cm long. In the final trimester the growth of the fetus continues with the time of 32 weeks being fertilized. At this point the offspring is approximately 3300g and about 40-50cm long.
Internal fertilization is when the sperm and egg cells meet inside the female body. The fetus starts to develop when the sperm penetrates the egg. After internal fertilization the embryo develops and is taken care of inside the mothers body. The advantages to internal fertilization are, it protects the egg. The embryo is isolated inside the female body and there is a greater chance for a successful fertilization. Some disadvantages of internal fertilization are, there are more limited amounts of offspring being created at any specific time. There are risks of catching sexually transmitted diseases. Sometimes it is harder for the male and female species to come in contact of each other.
Through the process of spawning, male and female fish and sea urchin release there sperm and egg cells that will unite outside of there bodies. When the sperm cell meets with the egg cell the fertilization process begins. External fertilization is more common for species living in the water. Some advantages of external fertilization are there are normally large numbers of offsprings produced. It is easier to find mate to create offsprings because gametes released often drift from wind and waves in the water. With external reproduction there can be more genetic variations of the offspring. Some disadvantages to external reproduction are there is no guarantee that the sperm will come in contact with the egg, leaving it unfertilized and wasted. There are environmental hazards such as predators which gives no guarantee the offspring will survive. -Angelina Johnston
A few principals of learning that I will be reflecting on are:
“Learning ultimately supports the well-being of the self, the family, the community,the land, the spirits, and the ancestors.”
I find this sentence to be very accurate and truthful, to be able to learn well it is very helpful when your family is applying their support for your interests. There’re students all around the world that feel alone and feel as if they have no support in their education in the community. If we all support each other a little more it would make a big difference to everyone. Most of the time you often hear children say ” I don’t like school ” you can not force a child to enjoy learning but you can encourage someone to enjoy it a little more. A few recommendations I have on how to send your support to others is to let them take the classes they want even if it is not a class that educates you the most. When a student gets to pick their own classes it feels independent and like you are doing the right thing all on your own. I believe that the message this principal of learning is sending is that education will be your supporter in the future.
“Learning involves recognizing the consequences of one’s actions.”
When a teacher is helping a student learn, the teacher has to notice how the student learns. If a student is a visual learner but the teacher does not teach visually then it will be very hard for the student to learn. This is my understanding on this principal of learning. Often at the beginning of the school year in previous classes I have been in, we would have to do a worksheet on the way you learn. For me I find that I learn better visually but for others that is not the case, which is which is why we need to recognize others learning styles.
“Learning requires exploration of one’s identity.”
Throughout life you find your way doing things you thought you might not have enjoyed doing, you take risks and learn from mistakes. During high school it is your time to experiment in different interest of yours. Taking many different classes in high school will help you narrow down your interests. If you never try then you’ll never learn and you may be missing an opportunity that could have turned your life into an amazing rollercoaster of excitement, but you never know until your explore your interest.
How Principals of learning is relatable to the activities we have been doing in class
Principals of learning relates to our SSEP experiment that we did earlier on in the school year. The Student Spaceflight Experiment Program purpose was to create an experiment that would potentially help the astronauts in space. Although my group did not win the contest, I am still able to strongly relate principals of leaning to the SSEP experiment. The propose of principals of leaning is to try to help others. The very few sentences of principals of leaning are all about how one can make a difference in someone else’s life. I also found that the First Nations principals of learning were very relatable towards engineering brightness. Engineering brightness is a project we have been working on to try and raise as much money as possible to donate to the Dominican Republic for light poverty. We have had many plans and activities going on to support the Dominicans cause. I am hopeful that others will acknowledge the principals of learning and will hopeful stand by them.
I am the reason she’s like this, it’s my fault. It is my fault the voices of her loved ones will never be heard through her ears. I made her this way and there is nothing I could have done. My name is Morgan, a young protein found on the (GJB2) gene. I am connexion 26, the main reason my host has non-syndromic hearing loss. My host Mckenzie, is a sweet 11 year old girl who was born with non-syndromic hearing loss. Mckenzie inherited this disease from her father.When my genetics were still being created and Mckenzie was still an infant inside the womb, her ears were damaged. Mckenzie was born with non-syndromic hearing loss caused by a viral infection in the inner ear.
Non syndromic hearing loss has provided many difficulties to live with, there are a lot more side effects then Mckenzie’s parents had anticipated. Mckenzie does not communicate verbally, instead she speaks with sign language. Well I would’t say she speaks it fluently but she’s learning. Mckenzie also goes to speech therapy three times a week and has been learning how to read lips. Mckenzie strongly relies on the four senses she has because she is missing one. She does homeschooling because she finds it extremely difficult to follow along in class by only reading lips. Mckenzie started homeschooling in the first grade deciding it would be a better option after being in school for one year (kindergarten). Not only has this syndrome effected Mckenzie’s life but it also effects her whole family’s. They have all been taking sign language lessons and they always have to be mindful of how fast the are speaking or how much they have to pronunciate.
It all went wrong when the DNA copied itself while the DNA was dividing. The copied pattern got mixed up and so the two identical DNA strips were no longer identical, which is a mutation. About one child out of every 500 is born or has developed hearing loss as a child.
Mckenzie appearance does not look any different from others. Despite her hearing loss the only thing that makes her stand out are her hearing aids. You might be wondering why someone would need hearing aids if they can’t hear anything at all. The hearing aids do not allow her to hear general sounds but they give her a better sense of her surroundings. The type of syndrome Mckenzie has is familial. Familial is a syndrome where you develop non syndromic hearing loss from a family member, in this case her father. Mckenzie also has sensorineural hearing which is when the the hearing loss is caused by having an infection in the inner ear as a baby.
In order to create my mutation story I needed to research about non syndromic hearing loss and I learned how someone with this syndrome would communicate. A few questions I asked myself in order to create this story were, how would this condition effect her family. How would the parents of a child with non syndromic hearing loss know their kid has the syndrome. How I would feel if I was born with the syndrome.
While doing this project I went on to youtube and searched about mutations and how they occur. I found a youtube video titled “How genetic mutation happens”. By watching this video I had a better image in my mind on what actually happens when genetic mutations occurs.
I started this project with picking my mutation then I searched about the topic. I read some articles and facts just to get a general idea of what the syndrome is then I wrote my story and included the important facts that really stood out to me.
I used a lot of different sources but the main two I found helpful towards this assignment I copied the links and added them to my blog.
I think the process went well and I enjoyed coming up with a story. In my opinion I think that I could have looked at more sources so I could have written one or two more sentences but I like what I have came up with and I feel did well on this assignment.
In Mr.Robinson’s science 9 class, our assignment was to make a DNA strand using liquorice, mini coloured marshmallows and tooth picks. DNA is found in the nucleus of a cell and it create your characteristics. DNA stands for deoxyribonucleic acid. The DNA you have are copy’s of your parents passed down to you.
There are four different types of nitrogen bases, (A) adenine, (T) thymine, (G) guanine and (C) cytosine. Their is always a pattern for the four chemical bases. The pattern we used in class was TAC GTA TGA AAC. As you can see in the photos their are two strands of DNA, the DNA strands act as a blue print for the other DNA strand. -Angie Johnston
2) Mr.Robison’s science 9 class was lucky enough to have a Skype call with the Dominican Republic and New Brunswick. Having the opportunity to speak with high school grade 11 students in a different country/province was a really cool experience. We had the chance to ask them many questions based on light poverty and lack of electricity in the Dominican Republic.
Our first Skype call was on November 24th 2016 speaking with the Dominican Republic. Two staff members from a private school in the Dominican named Dennis and Eladio gave us descriptive information about the electrical issues and light poverty they have were they live. They told us many facts and showed my class photos of what their housing looks like from the outside. Many buildings looked very rusted and had no power source. My class was split into groups and one student from each group was able to ask a question. My question I asked was “What are the conditions like at school and how does it effect you?” Eladia and Dennis responded by telling me about how little light they have during the day. We were told that in most places there is access to electricity for about 2-3 hours a day, some places have no power.
The elite private school in the Dominican Republic is lucky enough to have electricity and has the money to afford the use of computers, iPads, 3D printers and telephones. An elite private school in the Dominican Republic is equivalent to a regular public school where we live (Canada BC). In the Dominican, most public schools have no access to any power and mostly use daylight as there only source of light. During the day children are out in the cane fields where they are forced to cut cane for 14 hours a day every day because their families can not afford for their children to get an education.
Eladio and Dennis had very descriptive responses to all of our questions . I think the Skype calls were helpful towards our fundraising process because New Brunswick gave us good tips on shipping the lights and what materials to use. The Dominican Republic Skype call gave me a better understanding of the problems that are going on there.
3)My group of three has a goal to raise $500 dollars to supply the lights and shipping cost for sending solar powered lights to the Dominican Republic. To reach our goal we will be connecting with Pitt River middle school. The middle school will be helping us raise money by doing bake sales, making posters, announcements, exedra. Besides connecting with Pitt River we are hoping to get Kilmer elementary school to donate and help raise awareness. We feel that the more schools we have raising awareness, the more our community will donate. Getting more schools involved would help our fundraiser and would save a lot of families from light poverty in the Dominican Republic.
Below is a link of a power point my group has created. We made this power point to present in front of the leadership class at Pitt River Middle School on Tuesday December 6th, 2016. We created this power point so that the Pitt River students can have an understanding of what is happening in the Dominican Republic and our plans to support them.
When we talked in front of the leadership students at Pitt, they all seemed very enthusiastic about the whole idea of helping a different country where most people are living under the poverty line. When we had finished our presentation the room was filled with positive thoughts and tons of questions. We are all very exited to start our fundraising to achieve our goal of $500 dollars.
The orange will produce the most electric voltage because it is very acidic which will have the effect of adding to the electric voltage.
The orange created the greatest electric voltage out of all the fruits and vegetables we experimented on. The reason why fruits that are acidic gain more current electricity is because when a metal connects to any acidic material the electrons are given up by the atom. The acids benefit the battery in the circuit so the electrons flow nicely. The other fruits were very close in having the same reaction but the orange had more voltage by only a few segments. The apple had the least amount of electric voltage only by a few segments on the volt meter.
First we did the experiment on the yam and attached copper and a nail and stuck them into the yam. We hooked the wires up so they were attached to the two variables. During this experiment we realized that the experiment worked best on the the fruits and vegetables that were the most acidic. We tested a yam, orange and an apple. For the yam and the apple the volt meter did not move as much as it did when we created a circuit with the orange. The reason why fruits that are acidic gain more current electricity is because when a metal connects to any acidic material the electrons are given up by the atom.
Q. a) If your bulb doesn’t glow, how can you find out if electrons are flowing?
b) If your bulb doesn’t glow, why not?
Q. How can we modify our experiment to improve our results?
Q. What is causing electrons to flow in this experiment?
Ans. a) Even though the bulb will not light up, we noticed that the voltmeter would move either forward or backwards showing that the electrons were flowing.
b) Th reason the bulb did not glow was because there are not enough electrons flowing for fruits and vegetables to turn on a light bulb.
Ans. A way to modify the experiment is to add more acidic acids into the fruit to receive a better result.
Ans. The acids in the fruit and the chemicals in a battery are similar, most of the time the battery is the conductor in the circuit which causes the electrons to flow so the acidic acids in a fruit or vegetable causes the electrons to flow in this experiment.
My prediction was correct, the orange produced the most electric voltage. I was not expecting how close all of the results would be but the orange did produce the most electric voltage. Our most important finding was the yam and the orange had similar results but the orange had one more segment on the volt meter than the yam. I found this experiment interesting because it showed me that the more acidic a fruit or vegetable is the more electric voltage there will be. If we were to do this experiment again I would like to answer my question of does the temperature of the fruit or vegetable effect the results shown on a volt meter?
My group has been working on an experiment for the SSEP experimental space launch. Our group had many ideas for our experiment but the final one we had narrowed it down to was an experiment about bacteria. Our problem we are trying to solve is to see if we are able to kill bacteria in microgravity as easily as it is done on Earth. We came up with this experiment hoping to help the astronauts up in space so they can have better hygiene. My group and I started thinking about how the astronauts live in microgravity. We thought maybe they would feel more comfortable having a product that was able to kill bacteria quickly in space. By killing the bacteria in space we were planing to mix hand sanitizer with rubbing alcohol to kill the bacteria which would be placed on agar. Although our experiment did not get selected to launch up to space, this experiment was fun, hard work and it taught me a lot.
Microgravity is a very weak gravity, it is for orbiting spaceships. An experimental groups is the group that receives the variable, which is the material in the experiment that is always changing. The controlled group in an experiment is the group that does not receive the variable or any research from the experimental group. Since the controlled group does not receive any variables this group is used to be compared agains the other experiments tested.
Discovering research used for the experiment
I was able to bring back a few ideas from Heritage Woods Secondary school. There were a lot of interesting stations at the high school that were not only fun to see but were also helpful towards our experiment. The next day at school I had brought back all of my notes I had taken while being at Heritage Woods and I explained to my other group members what I had learned. We discussed many ideas on what experiment we where going to do, then we finally came up with the thought to do a bacteria lab. Everyone in my group agreed on what we where going to do so we started.
One of the very first assignments we had this year was looking in to prevues SSEP wining experiments. My group was doing research on a grade 6 class from Santa Anna,California in 2015. The students hypothesis was “Does microgravity affect the water absorption of Hyaluronic Acid (sodium hyaluronic)?” When astronauts are in space they tend to get very dry and itchy skin, this grade 6 class wanted to create a product that would help cure the dry and itchiness of astronauts so they would be more comfortable in space. In the students research they found that hyaluronic acid heals wounds, soothes burns and makes your skin moist. The reason why the astronauts became so itchy and have dry skin is because the aging process increases while in space. I believe that the grade 6 class won due to their thoughtfulness towards the astronauts needs while in space.
We are trying to solve the problem of killing bacteria in space. We came up with many ideas for our SSEP experiment but decided to go with our original thought on bacteria because we found it was the most interesting one to look into. Other thoughts we had for experiments were “how long will it take for a piece of cheese to mold in microgravity compared to on Earth?” We made this a possible experiment because we were curious to know. The reason why we did not end up doing our experiment on the molding time of cheese is because we figured that it might start to smell and we came up with the killing bacteria experiment instead. Besides the idea of cheese mold time we had came up with many ideas such as plant, fish and animal growth in microgravity. We were also researching whether centipedes would be able to help the soil grow in space compared to how they help the soil grow on Earth. Personally I found this experiment very interesting but we did not end up doing it because we were not sure how we would be able to test the experiment on Earth as well as in space. Members in my group did not show any interest for doing an experiment on centipedes so we decided to see if we would be able to kill bacteria in space as easily as it is done on Earth.
Designing and Delivering our proposal summary
Writing our proposal summary for our SSEP bacterial experiment was a very long process. We started out assigning different parts of the proposal to every person in the group so every one would do an equal amount of work. We quickly realized that we all had different strengths. A few people wrote the summary including myself then I edited the entire proposal because I had the strongest writing skills in the group. I found the proposal summary frustrating to take on because there was a lot of work to do with not many people working on it. To create the best proposal we could I spent lunch hours and my own time correcting all the wording from the paragraphs written. When our proposal summary rough draft was finished all members of the group had re-read the entire proposal so everyone agreed on the final product.
The most important part of the whole SSEP experiment was physically doing it with all of the materials (hand sanitizer, agar with bacteria on it and rubbing alcohol). The first step we did was mix and poor the hand sanitizer with rubbing alcohol into a beaker. Then we dipped a piece of hole punched filter paper confetti in the liquid and finally placed it on the bacteria plate. We did this three times, once with only using hand sanitizer, another with only using rubbing alcohol and the third time using both hand sanitizer and rubbing alcohol. It was very interesting to see the results and know how much bacteria was killed. The end results of this experiment was the mix of both hand sanitizer and rubbing alcohol which killed the most bacteria. Knowing our experiment could potentially be brought up . . … into space made me want to work as hard as I could on this project.
Debrief on how the experiment went
Personally I believe that all members in my group did well with communicating with each other, such as letting each other know if we did not understand a part of the assignment. Whenever we had a question we where not afraid to ask to make sure we had full control and completely new what we where being assessed on. Outside of school I had been connecting with my group members and we had been helping each other out for different sections of the assignment.
Something I wish we had done better was if everyone in the group would have done an equal amount of work. I found that a couple of people in the group hardly participated and did not show an interest in doing the work. When we assigned different parts of the proposal to every person in the group and some people decided not to do the work, it was very frustrating having to do an extra part your teammate was supposed to do, in order to finish the proposal.
For the most part I feel that this experiment went well. I put in a huge effort and worked to the best of my abilities. I know our experiment was not as good as other SSEP experiments but my group tried our best and worked as well as we could with each other.
