What do we do in Science class?In my science class we are learning about different things in life science. We will be learning about how earth began and other things we need to learn about. We are also learning more about DNA and genetics.

Quarter 1
In science we are learning about genetic traits. To know the child's trait we put the females Genotypes on the top of square and the males Genotypes on the left side. Then you have to cross them, so the G and G from both male and female go in the first box. Then cross the big G and lower case g and that goes in the second box. Then for the third box you use the males genotype Gg then for the fourth box use the male and female one which is gg. So far I have learned how to find a child's genes by using their parents genes.
Quarter 2
In my science class we did this project to see the DNA of a strawberry. First we had to get 2 strawberries put them in a bag and squish them until it looked almost like a smoothie. Then in another cup we fill 150 mil of water and a teaspoon of salt and soap. We mixed all those ingredients and poured it in the bag with the crushed strawberries then we mixed them all together. Then we got a coffee filter, covered the cup and poured in the mixed ingredients, then we added rubbing alcohol. After that the strawberry DNA rises up. Then you use a stick to take out the DNA which looks like white stuff. This experiment was fun and I learned a lot about DNA.
Quarter 3
In my science class we are learning about DNA and how it was discovered. We have talked about Rosalind Franklin, James Watson and Francis Crick, Erwin Chargaff, and Maurice Wilkins. We have learned what all of them did to find everything about DNA. We have also learned how DNA replicates and why we need DNA. I have learned why we need DNA and how it was discovered. This unit in my class is very interesting.
Quarter 4
In my science class we learned about the eye. To learn more about it we dissected a cow eye. First we had to cut the fat around the eye then cut it in half but cut close to the cornea. Once it was cut in half you could see the lens, pupil, iris, and many different things. I learned how the lens makes an upside down version but once it gets to the retina its not upside down anymore. It was cool how we could see some of the parts that are inside our eye.
