CBL artifacts of learning

2) The whole process started off a little bit slow with generating ideas.  Once we sat down in our groups and discussed how we wanted to impact people’s  lives. Skype chatting with Eladio and Dennis from the dominical Republic really broadened my knowledge about light poverty across the world. The next skype chat we had was with Mr.Fogarty and his students from New Brunswick. That chat was interesting for me because of Mr. Fogarty really explained his process and the tools that he needed and used. a lot of supplies and expenses was needed to create the lights. My group decided that we would help the most if we would fundraise money for the costs and expenses of the materials needed to actually create lights for those in light poverty. we struggled a bit finding time and dates to hold the Fundraisers and really only wanted to only put our best work forward. We eventually decided to create a class video, where we would interview all the students in the class and ask them their story and contributions for engineering brightness. The video above features some of the students from our class that really succeeded in many ways. Interviewing my peers was uplifting of me because I realized that not many kids get the opportunity to actually build lights or be involved with a process like this and I am grateful that I got to experience it. I feel that with this video clip created by my group and I posting it on social media platforms such as youtube is a great way to get the word out here and I truly believe that it will help address the problem with light poverty and bring awareness.

3) Working in a group has always been a little tough for me because I tend to not voice my opinion or contribute as well as others. After working with my group I really feel that I have developed a skill in teamwork. Also communicating and emailing back and forth with other educators broaden my skills in digital communication. working with my group was the highlight of my experience and  I feel that I have met my learning goals because now further going into the future and working with other peers through my years at high school and life,  I don’t feel that I will be afraid to step out of my shell and contribute my work forward.

4) In my opinion, the collaboration went very well and successful. We created a Video clip of our classes experience and brought awareness to light poverty in The Dominican Republic and across the globe.  Working with others can be challenging at times because we all have different takes on situations and thoughts. I would say that the thing we could improve on is thoroughly planning ahead and not taking it day by day. In some cases taking that approach has worked to my advantage but most of the time things come out clearer and more successfully when you plan ahead and prepare, in my opinion. One thing that I did well was taking in everyone’s thoughts and ideas and respecting them. I felt that our group felt comfortable expressing themselves. I feel that the connections based learning experience was a positive way of learning. I learned things via skype chat etc that I have never done before. It really opened up my knowledge and made me creatively think in new ways.  I think over all connections based learning and engineering brightness helped me step out of my shell and look at new ideas or things in a new positive way.

 

 

How do cells multiply

Asexual Reproduction:

  • Asexual reproduction is naturally how clones are formed. Clones are used in agriculture and research in order to develop dissed organisms, tissues and genes. Budding, fragmentation, vegetative reproduction, and spore formation are all types of asexual reproduction. One organism that reproduces by budding is bacteria and yeast. An example of fragmentation is annelid worms, mitochondrial eukaryotic. Organisms that use  Vegetative reproduction are plants and crops such as corn, apples, mangoes and avocados. organisms that reproduce by Spore formation: Eukaryotic organisms, plants, algae,
    and fungi.  Some advantages of asexual reproduction are, large numbers of offspring are produced very quickly from one parent. Another advantage is that energy is not required to find a mate. And lastly large colonies form that will out-compete other organisms.  Some Disadvantages of asexual reproduction is when you have one negative mutation, it can affect the whole offspring and can destroy large numbers of offspring because they are all genetic clones. Another is the fact that uncontrollable conditions such as extreme temperature change can wipe out entire colonies.

Sexual Reproduction

  •     The production of a new living organism by putting together genetic information from two different individuals (male/Female). One individual (male) produces a small gamete that travels to fuse with a larger gamete produced by the other (female). What sex a baby will be is decided when the egg and sperm meet. Each egg and each sperm have one sex chromosome. There are two kinds of sex chromosomes X and Y. Eggs carry only an X and sperm carry either an X or a Y. X+X means the cell will develop into a  girl. X+Y means that it will develop into a boy. Once you are born, you will grow up into a unique human being there’s no-one else like you in the world. Even identical twins are not exact copies of each other they each have their own personalities.

 

Mitosis; a process that divides and genetically copies cells. ( 4 stages/ PMAT)  

Early Prophase

  • The replicated chromosomes coil up into x-shaped chromosomes.
  • the nucleolus will disappear
  • the nuclear membrane will begin to break down
  • spindle fibers begin to form

Late Prophase  

  • the spindle fibers complete forming
  • chromosomes attach to the spindle fibers

Metaphase 

  • the spindle fibers pull the X-shaped chromosomes into a single line across the equator of the cell

Anaphase

  • spindle fibers begin to contract and shorten pulling the chromosomes apart
  • the sister chromatids move to opposite poles of the cell
  • once separated there are all considered chromosomes

Telophase 

  • there is a new complete set of chromosomes at each end of the cell
  • spindle fibers disappear
  • nuclear membrane reappear around each set of chromosomes
  • a nucleolus appears the cell can now divide.

 

 

 

 

 

Miosis

  • MEIOSIS I:  Pairs of chromosomes are lined up at the center of the cell and then pulled to each side. Meiosis is a bit different than mitosis because there something called crossing-over happens with the DNA. This crossing over is an exchange of genes. Normally the cell would begin to go about and slowly duplicate the chromosomes for another mitosis division. Since this is meiosis, there is a very short interphase and division begins again.
  • MEIOSIS II: In Prophase II the DNA that remains and the cell begins to condense. Each chromosome pair has a centromere. The centrioles also begin traveling to opposite sides of the cell. In Metaphase II all of the chromosomes line up along the center of the cell for duplication. Anaphase II,  the chromosomes split and move to opposite sides of the cell. Each one splits into two pieces. They don’t divide up the DNA between the new cells; Each daughter cell will get one-half of the DNA needed to make a fully working cell.

Organism growth 

Pollination; pollen is a substance that is powdery typically yellow, it is discharged from a male plant. pollen is transferred by bees, hummingbirds, moths, the wind, flies, and people.

Fetal development; Embryonic development is the stage that occurs before the fetus begins to develop. (There are 3 trimesters or stages)

  • The first trimester; developing an organ system. Time from fertilization= 8 weeks. length of embryo/fetus= 9cm
  • The second trimester; growth of the fetus, time from fertilization= 12-16 weeks. Length of fetus= 35cm
  • The third trimester; continued growth of the fetus, time from fertilization= 32 weeks, length of fetus= 40-50cm.

External Fertilization; Through a process called spawning a male and female fish would release their sperm or egg cells that unite outside their bodies. When the sperm cell reaches the egg cell that’s when the fertilization has begun. This process is normally common with underwater species.

genetic mutation story

 part one

When you do not have enough red blood cells or when your red blood cells do not function properly you have a problem, which is me. Anemia is my name,  most people can experience symptoms of me when a young child and other can experience me at whatever point of their life. I can occur in recent blood loss.  My main cause and issue that affects people are that I  lack the process of producing red blood cells.  Your body produces blood cells, one being white blood cells which fight infection.  Another is red blood cells carry oxygen throughout the body. Red blood cells contain hemoglobin an iron protein that makes your blood red. My main cause is recent blood loss, trauma, surgery, and other events play a huge role in the diagnostics of me. If enough blood is lost, your body may lose red blood cells and the chance to reproduce them. I can be either acquired or inherited. acquired meaning you can develop me, inherited meaning that your parents passed the gene on to you. many effects that I have on my hosts body include general weakness, pale skin, shortness of breath, dizziness, wired cravings (to eat not food items), such as dirt, ice, or clay,  tongue swelling, cold hands and feet, fast heartbeat, headaches  and many different occurring situations depending on the severity of my mutation. I affect lots of aspects of daily life, one including stunted growth. My host inherited anemia, as a child she was always shorter and smaller than the other kids. She has to stay on a strict diet. Some of the food in her daily diet include; apricots, asparagus, bananas, broccoli, egg yolks,  plums, prunes,  raisins, squash, turnip greens, whole grains, and other dark green vegetables. My host plays soccer,  a symptom of anemia is shortness of breath, she often has to sit on the side and regain a strong breath before she can continue. Another problem my hosts faces of her pale skin, she looks sick and tired all the time, she often gets made fun of.  People call her names like a ghost and other hurtful things. She doesn’t let that get in the way of her difference,  she knows she can’t change it and continues on it life with a positive outlook. The treat meant of minor anemia is fairly simple, in most cases, people will have to make a change in diet, take supplements, and different types of medicine. In other cases where anemia is severe procedures like blood transfusions or blood marrow stem cell transplant. 

Part two

In order to complete a story about anemia, I really had to make sure I had a great understanding of what the disease was and its effects. Some questions I had to look up were; what are the symptoms of anemia, what is anemia, does anemia impact the quality of life, are there different severities of the disease, and how does anemia occur. To create this project I used a few digital tools including google, Wikipedia  https://en.wikipedia.org/wiki/Anemia,  Health Link BC https://www.healthlinkbc.ca/health-topics/abq1897, and medicine.net http://www.medicinenet.com/anemia/article.htm. The process of investigating the topic was a bit challenging for me because it was hard to understand the mutation and how it was caused. After further researching Ibelive that I have a pretty good incite on this mutation. The process of completing this project was fun writing the story and pretending to be the mutation inside someones body. One thing that I could have done better into add more detail into what I’m talking about and to research a lot more that way I have more knowledge to add to detail.
