I really liked the dissections, even though it smelled awful. We dissected a frog, starfish, earthworm, crayfish, grasshopper, and a sheep brain. Ms. Seyda showed us how the frog had two major muscles in its leg, one for flexing and one for extension. We learned a song about the water vascular system and all the parts of it because it was the starfish's vascular system. The earthworm is valuable to scientists because it has sections that can help it move through dirt and scientists study why. The crayfish has a really cool exoskeleton, or shell, that protects it and keeps it safe. It has no veins! Blood pumps from the heart and travels through tissues to the rest of the body. Grasshoppers, despite their sometimes unappealing look, they have a thin, beautiful red layer of their wing under the main wing. They also have an exoskeleton to protect them. The sheep brain, similar to ours, has a cerebellum and cerebrum. It also has two layers of tissue protecting it and keeping everything in place. Over all, I had a great time, I learned a lot, and our teacher is really smart and nice. I would definitely recommend this course.
