Pig Dissection

The pig dissection was a very interesting way of learning about anatomy. The purpose of the lab was to help us see where and how the organs work together. The pig has the same organs as humans do, so we could see the anatomy of the pig. In previous vodcasts, we learned about the Circulatory, Respiratory, Nervous, Endocrine, Digestive, Immune, Lymphatic, and Inflammatory systems. Throughout dissecting the pig, we saw all of the systems. Some parts were harder to find than others, because they were underneath, so we had to dig a bit to find it. My favorite part of this dissection was cutting open the heart and seeing the veins. This was interesting because we could see the bright red and blue veins.

Unit 10 Reflection

Unit 10 was about the many systems in our body. The circulatory system pumps blood throughout our body to provide oxygen. The respiratory system puts oxygen into our blood. The nervous system helps us move our body and think. The endocrine system controls the body's reproduction, growth, and metabolism. The digestive system processes food into and out of our body. The immune system helps our body fight against disease. The lymphatic and inflammatory both help the immune system fight bacteria.

I want to learn more about the nervous system, and how it sends signals to tell our body what to do. I wonder why our cells automatically do what they do.
Throughout this year of biology, I really enjoyed the What on Earth Evolved presentations. (What on Earth Evolved: Apple). The Hunger Games Lab was also very enjoyable and memorable. (Hunger Games Lab). I've learned a lot and become better at biology.

20 Time Final Post

For my 20 time project, I researched what would help me wake up on time. I did this because I hoped my results and research would help others too. I found a good combination for setting my alarms so, that it would wake me up on time and also without being groggy. 

My TED talk was much longer than I expected, 5:55. When I practiced my TED talk at home, I got the time of 3:55, so I may have talked much slower. I also may have added more things in my presentation, adding on to the length of my presentation. I could do my presentation again, I would practice my introduction better so I wouldn't have as many "uh"'s. I enjoyed listening to other people's presentations as they were very interesting. I have learned a lot about myself, and learned more about other topics. Prepping for this was more stressful than for the what on earth evolved presentation because I couldn't read off anything.

20 Time Reflection

20 Time Individual Reflection

I challenged myself to find a way to help myself and other to have an easier time in the mornings. I chose this because I have trouble waking up in the mornings. I want to improve my mornings and also help others too. I will use the research and information I have gotten to wake up easier every morning and also help others.
My project helped me learn a lot about different ways people can wake up, and how each person is different. I can't concluded what is the overall best method for waking up, because other people may respond differently, but I know what helps me wake up the best. I experimented with alarms, trying different methods to wake myself up, and I found that two separate sounds helped me the most. One loud sound at first, and ten minutes later a more quiet one that I hear, that tells me to get up.
If I could do this project again, I would make the survey earlier, so more people could take it. I will continue sharing my results and methods with others, so they can see what helps them the most.

Unit 9 Reflection

Unit 9 was about how organisms in the past evolved to form all the organisms today. We learned about how organisms are classified, and the differences of organisms. We went on a field trip to California Academy of Sciences to do a scavenger hunt. The building had an entire ecosystem on its roof, which helps lower the destruction of habitat. It helped review the unit and see many things. Also, I made a presentation (What on Earth Evolved Presentation) describing an apple and how it evolved. We even did a little bit of research on Sponges. 

 

I want to learn more about the past, and how our ancestors were. The earth in the past may have looked like a completely different planet, so it would interesting to see what it looked like. We watched a video series called "My Inner Fish," and it showed the similarities between a fish and a human (My Inner Fish Reflection).

The presentation I made was very time consuming to make, and I could have started doing it earlier. I could have rehearsed my presentation more before I presented, so my presentation would have flowed better.

My Inner Fish Reflection

The video series was about how evolution in past species has led up to humans. We've learned about evolution, and this series shows proof of evolution.
 The human skeleton and the fish's skeleton are actually related, having similar muscles and bone structure. The human skeleton had come from the fish's skeleton. Many species had common ancestors, like a chicken and a human. Fish gill slits are still on human and chicken embryos.
Mass extinctions are important because they give other species a chance to flourish. When dinosaurs were around, mammals had to hunt during the night and sleep during the day. Because the dinosaurs all went extinct, mammals had a chance to thrive. Extinctions give other species a second chance.
