My Evinronmental Interactions

                                        Interactions with the Environment                                      Sabrina Sharifzada

 

On a regular day we have many interactions with the environment, although we never put the time to think about it and understand the positive and negative consequences that our interactions have on the environment. In this assignment we are supposed to write down a few interactions that we have on a regular day and their consequences to the environment. Here as a few of my interactions which I have reflected on and thought about.

 

Automobile travel:

Automobile travel is the first one. When I go to school and come back home I need my parents to drive me. However I really didn’t take the time to think about the consequences that my action engraves on the environment until now. The consequences that cars can create are devastating. Cars let harmful gases, CO2, etc…which pollutes the air and also creates global warming and climate change. Global Warming is when the total temperature of the earth rises quickly melting glaciers and icebergs in Antarctica and other cold areas. The harmful gases an Co2 is locked in the atmosphere and that is what causes the rising of temperature. It also affects the biosphere (humans, plants and animals) by causing dangerous diseases and also reduces the growth of plants and trees. I never really thought about this but our cars need gas and to get gas they need to create pipelines which can leak into lakes and other places where marine animals live. But the reason I do this is because I carry a lot of things to take home and to school and also from school to my house there is a lot of uphill and downhill the weather is also a problem sometimes. My plan is to walk to school and home after the weather becomes better (spring). We can reduce air pollution by using public transportation, planting more trees (they take in CO2 and let out oxygen), walking, etc…

Leaving the tap running:

When I wash the dishes or brush my teeth I usually leave the tap running (by accident). I seem to forget the consequences that my action has on the environment and the hydrosphere. Water is very valuable and something that not every country has access to, so we need to be extra careful and keep the hydrosphere safe and be aware of what we do.  During the summer the City of Port Coquitlam usually tells residents to use less water and only allowing to water plants on certain days and requesting to not wash your cars too much. When I searched online to find out why they are doing this, I found out that we need to conserve water because the population is growing and the environment is changing. As well as leaving water for public health and environmental sustainability. From now on I will try to remember to not leave the tap open. Another great thing to do is when you’re washing your plants or vegetables put a container in the sink so the water that is used goes into the container and once it’s full you could water your plants (that way water isn’t wasted).

A useful resource that I found to helped with research:

Usage of plastic bags.:

Regularly we all use plastic bags when we go shopping (including me). However it has become a habit and sometimes forget to bring along reusable bags with us but we also seem to forget the consequences of our actions. Plastic bags are very useful when shopping or just everyday use. Although many plastic bags are made from crude oil and natural gas and during the creation of the plastic the factories pollute the air and the atmosphere.  Last year in a documentary that we watched in school it showed that a lot of plastics are non-biodegradable and because landfills and the geosphere are overflowing so they are throwing plastic and garbage in the oceans and in the hydrosphere which pollutes the waters and also kill many marine animals and their ecosytems. I had a Visual Journal that we would reflect on and one of my reflections were on plastic use but unfortunately I have lost it and I am not sure where it is.  Many stores are charging a fee for plastic bags but that still isn’t stopping people from using plastic bags. From now on whenever we go shopping I will try to remember to bring reusable bags to reduce pollution in the air.

Engineering Brightness Artifacts of Learning

                                 Engineering Brightness Artifacts of Learning                                                Sabrina Sharifzada

 

 

For the past month and a half we have been working on a project called Engineering Brightness. Our class has been divided into groups and each group has been working very hard on raising awareness and responding to light poverty in various ways.

My group has been collaborating with Pitt River Middle School to help us fundraise in their school. The Pitt River Leadership team was very enthusiastic and passionate about this project and they really did want to make a change. We had two meetings (one meeting before winter break and one after winter break) with them so far to discuss what they want to do for fundraisers and we also talked about how we need to raise awareness around the community and not just one school. In this time we mostly have been planning. They said that they are having a bake sale on the week that semester two starts. We also are planning to go with Pitt River to school visits were they go to different schools in the community for their leadership program but they also asked us to come with them and talk about light poverty and Engineering Brightness, although they’re not sure of a date yet since not many schools have responded yet. Although we know what school to go to when the date it known. We did make posters for the Bake Sale in Pitt River and also made a PowerPoint to introduce light poverty to people that don’t know what it is and what they can do. This will also be the presentation that we will present at the school visits when the date is organized. When we go to the schools we are pretty much just going to talk about the light poverty in the Dominican Republic and what they can do about it. We also contacted the Eddy and our friend that is in the Eddy, interviewed us and spread the word throughout the school.

This project has helped us get better with our presentation and communication skills. It also helped us with critical thinking. Collaboration was key because if we never connected with Pitt River we probably wouldn’t be here. This also showed that it’s better to come together as a community and try to solve a problem where the results would be better than doing something alone. This did have us go out of our comfort zone and do big things in the community where we never really had done. Most of this time we have been panning out possible things we can do. We haven’t really got any money but we are still in the process of fundraising and raising the awareness. Pitt River is excited and this may be something that they would probably wanting to continue throughout the year. We have achieved most of our goals as far as raising awareness and collaborating with other school. However the raising money part is still going on and we also will reach that goal soon.

Throughout this project, we figured that the more that we spread the word around the community the better. In my opinion I think that collaborating with Pitt River was a very smart thing to do and it was something that nobody else in the class did. When we introduced this idea to Pitt River the were very excited and enthusiastic about it. In my opinion,  I think that we worked well in our group and that each of us helped each other to get this far. We could have improved on raising more money and planning more fundraisers but we didn’t have a lot of time to do everything. However we are still fundraising to cover the costs of the materials that is needed for the lights. Over all I think that we did an amazing job in this project. We did our best and did what we can to get the word out in the community. I am very proud with what we did in this period of time and I think that we did make a difference. This experience has been one of a kind and something I have never done. I am very happy because our class actually made and did things and had the chance to connect with other people in different schools on the other side of the earth. We are very fortunate to do something like this since many other science classes don’t do these type of projects. I believe that learning is not only what we do in school but take that and incorporate it in the real world.

 

 

 

 

 

 

 

 

How do cells multiply

                         How do cells multiply                                         Sabrina Sharifzada

The Cell Cycle:

The cell cycle is what cells go through in order to create more cells. The cell cycle has 3 stages which are interphase, mitosis and cytokinesis.

http://science.halleyhosting.com/sci/ibbio/cells/notes/ch11/cellcycle3.gif

Interphase:

This is the first and the longest stage in the cell cycle. In this stage the cell grows in size and replicates DNA.

Mitosis:

Mitosis is the second stage in the cell cycle where all the contents of the cells nucleus duplicate. Mitosis has four phases which are prophase, anaphase, metaphase and telophase (PMAT is a way to remember it). During prophase the nuclear membrane and the nucleolus disappears and the chromosomes join together into sister chromatids (joined by a centromere). In metaphase the sister chromatids line up the equator of the cell. In anaphase the spindle fibres pull the chromosomes to opposite ends of the poles. And the last step of Mitosis is when everything is replicated and is ready to become into two cells.

Cytokinesis:

The cell divides into to two separate cells with the same exact DNA.

Meiosis:

Meiosis is pretty much the same thing as Mitosis but it is PMAT x2 as well as this needs two parents unlike mitosis which needs one. Instead of making regular skin cells the process of Meiosis creates sperm and egg cells. The other difference is that in when a cell goes through mitosis it creates two cells by the end of Cytokinesis but in Meiosis it creates four sperm cells in the males body and one out of the four cells become an egg cell in a female, the other three are polar bodies and aren’t much of use. Just like mitosis, meiosis also has interphase. During interphase each of the homologous pair of chromosomes is replicated. Homologous meaning that they are matching chromosomes one from each set (mother and father). During the first round of PMAT which I will refer to as Meiosis 1, and then the homologous chromosomes separate into two cells . Then in Meiosis 2, the chromosomes don’t replicate but the sister chromatids end up separating and creating four cells. And in each cell that is created there is only 23 chromosomes.

 

Sexual Reproduction:

Sexual reproduction is when the sperm and the egg cell come together and the from a new organism such as a baby. There are three steps in sexual reproduction which are mating, fertilization and development. Mating is when gametes also known as sex cells come together at the same time at the same place. there are two ways of fertilization which are external and internal fertilization. Internal fertilization is when the sperm cell meets an egg cell inside the females body. Pollination is basically internal fertilization but for plants. Pollen is yellow and powdery and carries the plant male gamete to the female reproductive system and then the pollen tube transports the sperm cell to the egg cell. After that fertilization occurs and the zygote grows into an embryo and nourished with the food that exists in the seed.  External fertilization is when the sperm and the egg cell meet outside the body of the parents. External fertilization mostly occurs in underwater species. The results of fertilization whether it’s internal or external, a zygote is created and contains 23 chromosomes from the mother and 23 chromosomes from the father. A zygote then goes thorough mitosis  and cell division then and becomes an embryo. However for a zygote to go through cell division the following conditions nee to be met which are; there must be enough nutrients for the embryo is divide, the temperature has to be warm enough so the enzymes and proteins can function properly when they go through chemical reactions, there must a certain amount of moisture in the embryo so that it doesn’t dry out and lastly the embryo needs to be protected from ultraviolet radiation as well as predators. Embryonic development is the early development in their offspring and occurs after the first two months after fertilization. Then there is fetal development where there is three trimesters and each trimester is 3 months long. During the first trimester, the organs, the brain and the spinal cord develop and the embryo is then called a fetus. The second trimester the mother can feel the baby moving and weighs 650 grams. In the third trimester the fetus grows and prepares for birth, major growth in the brain and fat is produces under the skin of the fetus.

Asexual Reproduction:

Many organism naturally form clones through asexual reproduction. A clone is an identical genetic copy of its parent. Cloning is also used agriculture and research to copy desired organisms, tissue, and genes. In asexual reproduction there is only one parent needed. There are many types of asexual reproduction such as binary fission, budding, fragmentation, vegetative reproduction and spore formation. Binary fission is when single cell organisms split into two identical copies and some examples are amoeba and algae. Budding is when areas of multicellular organisms undergo repeated mitosis to form an identical organism and some examples of it are sponge and hydra. Fragmentation is when a part of an organism breaks off and the grows back with the clone of its parent and a example is starfish. Vegetative reproduction id when special cells in plants that develop in to structures that form into new plants identical to its parent and some example are strawberries and potatoes. Spore formation is when some bacteria, micro-organisms, and fungi can form spores – single cells that grow into a whole new organism and some examples are fungi, micro-organisms and some bacteria. There is two types of cloning which are human assisted cloning and also therapeutic cloning. The purpose of human assisted cloning is to create desired results with organisms. And the purpose of therapeutic cloning is to correct health problems.

First Peoples Principles of Learning

First Peoples Principles of Learning                                    Sabrina Sharifzada

 

 

The two aspects in the First Peoples Principles of Learning that I am going to connect to, are interconnectedness and sustainability.

In beginning of the year, me and my class participated in the SSEP project which was a project that we got to choose a experiment and in the end all experiment proposals would go to the judges. The judges would then assess everyone’s and choose one experiment and send it to space to conduct that groups experiment. I noticed this project had a lot of sustainability because there had to be a reason to this experiment if we wanted our experiment to be chosen. We also had to state what benefits this experiment would bring to our world for future generations in one of the sections in the proposal.

We have been doing a project called Engineering Brightness which our goal is to send flashlights to the Dominican Republic to villages where there is no electricity. Me and my group are fundraising so that we can buy the supplies for the building of the lights. In this project I noticed that there is a lot of interconnectedness in this project since we as a class have been contacting the Dominican Republic as well as New Brunswick. Me and my group have been also collaborating with Pitt River Middle School and also was planning to go to Kilmer and other elementary schools in the community.

 

Learning involves generational roles and responsibilities:

During the SSEP experiment me and my group divided the proposal sections throughout the group so it could be done efficiently and equally. Unfortunatley some people in our group didn’t take it seriously and broke our group trust but there was someone in the group who helped a lot in the proposal with me which made me want to group up with her for future group projects. In our EB project I teamed up with people that really care and we mostly do many things together but I had the responsibility to create the posters and Janna had the responsibility to keep in contact with Pitt River. However all of us try to make it to the meetings with Pitt River’s Leadership team which is also a responsibility that each of us have.

Learning involves patience and time:

The Engineering Brightness does involve a lot of patience and time. Nothing is done in the blink of an eye, we did many planning, took the time to create presentations, posters, contacting another school. We needed to give them time to think about whether they want too help us or not. We also have to contact through email and plan when we are meeting with Pitt River. We also have to go on our own time to the meetings so that we don’t miss school. We have to be patient because not everything goes the way we want it to.

Learning requires exploration of one’s identity:

Throughout these projects I learned many things. Both of these projects will be an experience of a lifetime. This is the first time I have actually gone out the real world trying to solve something (light poverty) and also done a project where mine experiment had the chance to go to space. I got the chance to revisit my previous school. I have explored many things in these two projects that I haven’t in other school projects in my previous years of education. Throughout these projects I explored through various emotions and feeling such as frustration, nervousness, excited, happiness,  being proud of something, etc…

Learning is embedded in memory, history, and story:

The Engineering Brightness Project have created many memories with friends and also got to meet new people. If I get to state my interesting experiences in my resume, I would surely have this in there. Last year we had to write out our life story as an assignment and if I ever had to do something like writing out another story I would have my experience in there. This has been a experience in a life time and I hope to make the best of it.
