My science class is currently studying the basic unit of life, cells! This is a project that we have done in class. As you can see, it is made up of edible material for our edible cell project. This cell is an animal cell since it doesn't have a cell wall. Our class is also researching and observing how cells divide or cell division. From learning about cell division, we are able to identify the different stages of the creation for an organism.
The subject that our science class learnt about was genes and human reproduction . We learned about :DNA, genetic mutation, extracting DNA, and how how DNA looks like. A DNA molecule looks like a twisted ladder or double helix. We also learned how proteins are involved with DNA replication ,and how the structure of DNA allow cells to replicate. Genetics involved the use of a punnett square to figure out the probability of an offspring. The process of heredity, passing genetic material to offspring ,is very interesting. We learned the different body parts of male and female reproductive systems too.
The third quarter of science, our class is focusing about the Secret of Photo 51 and how it was obtained or copied. Students in different groups of four have to write notes documenting about either: Rosalind Franklin, Erwin Chargaff, Francis Crick , and James Watson . We have to write about the education , personal information, career ,contributions to DNA discovery, and why the scientist is worthy if winning a nobel prize. We also watched a PBS NOVA video about the documentary of the scientists and the secret of photo 51. Turns out that the scientist responsible for creating Photo 51 was deceived by her own partner and left as deception.
In science fourth quarter, my group and I were working on our animal project. My animal was a Brown Pelican, and I was assigned to find the classification and general facts of it. Since every group in our class had a different animal, all of us did not study the Brown Pelican. After, our science class went to the zoo to study our animals, we began to learn about light, eyes, and optic illusions. We learned the order of which light rays extended the most from greatest to least: red, orange, yellow, green, blue, indigo, and violet. Also, our class dissected a cow's eye to study the inside of eyes. We got to observe, analyze, and learn the functions and abilities of the eyes . This experience gave us a benefit of how an eye would look like from the outside and the inside too.
