Here are a few pics/videos from the Marine Biology Trip. We would like to thank everybody at PEEC for making it such a wonderful trip!
Students participated in a natural selection simulation called Let’s Grub on Some Grass Beetles. Play and listen to the video on how it was done.
Students constructed 3 dimensional paper DNA models. They learned that DNA is made up of nucleotides. Each nucleotide is comprised of a phosphate, deoxyribose sugar, and a nitrogen base, which can be cytosine (C), thymine (T), guanine (G), or adenine (A). Students then had to answer questions based on the model. Here is a slideshow of the students.
During the cell unit students learned how cells unlock energy in food. More specifically in the mitochondria oxygen reacts with glucose to release energy, carbon dioxide and water. In the video below students got to observe yeast cells doing this process. Bromothymol blue solution turns yellow when carbon dioxide is present. Watch and listen to the video for further explanation.
