During the year, we will have the opportunity to handle and or observe Rats, Snakes, Cockroaches, Hydra, Leeches, Goldfish, Tadpoles, Frogs, Earthworms, Snails . . . and much more.

Edible plant cell
In science class we were assigned to make an edible plant cell. If you don't know what that means, it means something you are able to eat. We were given a list of parts that needed to be on the cell. There were 12 parts that needed to be on the cell and there were 4 people in each group. If you do the math, this means that each person in the group had to at least bring 3 items. The next week, everybody brought their stuff and they had to put all of it together in 45 minutes. From this project I learned how to memorize all the parts and functions of plant and animal cells and how they worked.

Strawberry Experiment In science class we did an experiment where we looked at strawberry's DNA. First, we had to crush two strawberries in a plastic back, because it breaks open the strawberry's cell walls. Next, we we added 150 mL of water, salt, Enzyme, and dish washing detergent into a scientific measuring cup, because all that breaks open the cell's membrane and nuclear membrane. Then, we poured the crushed up strawberries into the cup, because it separates the strawberry's cell wall from the DNA. Finally, we slowly poured some very cold rubbing alcohol into the cup, because the alcohol causes the DNA to precipitate. I enjoyed this experiment, because I finally got a chance to see what strawberry DNA looks like. The white bubbly stuff in the glass to the left is the strawberry's DNA, and it is separated from the strawberry's cell wall and cell membrane.
