Stem Cells (Take 2)

Since our previous blog, my opinions of stem cell use has not changed. I still believe that its okay to use embryonic stem cells. Most people believe that its immoral but for the embryos that are already donated, they're going to be thrown out anyways. So, might as well use the stem cells for people who need them. If these cells are able to help with certain diseases and made people more healthy, why shouldn't we use them? It just seems so logical. I also believe that the use of adult stem cells is good too. These pre-determined stem cells can help patients organs function properly. What's so immoral about curing a person of a disease or bad organ? Stem cells are of good use.

Homeostasis

In the morning when you wake up, one of the physical changes that you go through is the movement of muscles. When you try to grip something really hard, you can't because your muscles are still "asleep." Also, your breathing changes when you get up to quickly and walk around fast. It speeds up to circulate all of the blood. The organ systems that are involved is the nervous system, muscular system, and circulatory system. You're nerves let your brain know when something in your body needs to be fixed or cared for at the moment. The feedback loops that are included in maintaining homeostasis and tending to wounds are positive and negative feedback loops. Negative feedback loops maintain homeostasis and positive feedback loops immediately tend to cuts and burns for permanent fixing while negative feedback in tending to homeostasis fluctuates.

Photosynthesis Rap

The photosynthesis rap definitely helped a lot to understand the process of photosynthesis so much better. The reason for this is because while writing the lyrics, you really had to think about all of the steps which forced you remember them. Rapping about photosynthesis was fun but although Sarah and I had a good time doing it, it was really hard to think of rhymes, find the instrumental version of Independent, and rap the words all together. We had lots of troubles staying on beat. Also, it was difficult to complete this assignment in the amount of time we had. To make this project better, I think we should have had another day to do it. But all in all, it was helpful and fun.

Thanksgiving

Thanksgiving is one of the most important holidays that really bring together family and friends to think about and give thanks to what they are most thankful for. Me, I'm most thankful for my health, family, friends, and all the opportunities in life that I'm getting that some kids never ever will get to experience. You don't really realize how lucky you are until you think about other people around the world who don't get half as much things as you do. I'm so thankful that my parents can provide me with food and shelter. Better yet, I'm thankful that I even have parents. Although Thanksgiving is just one day that people give thanks, we should really do it every day of our lives. 

Science Fair Projects

Yes, science fair projects help to teach science. While doing the projects, it basically forces you to look up information on the subject your doing it on, making you learn about that subject. Doing the experiment also teaches you about the scientific process, learning how to record things, and learning how to interpret your results and make it into a conclusion. Science fair projects definitely teach you a lot about science. 

Stem Cell Research

I think the use of stem cells is a good thing. Like the lady in the video, your body might reject a replacement organ but if all of the cells are killed in the organ, your own stem cells can come in and take it over so its pretty sure that your body will take in the new organ.
