Class Snapshot: Creative Chemistry
Morgan G. (Science) reports that 10th graders in Conceptual Chemistry have been hard at work in the lab, creating:
Lava lamps: students used water, food coloring, vegetable oil, and Alka Seltzer tablets to make their own lamps; Alka Seltzer reacts with the water to form carbon dioxide, which then causes those signature bubbles.
Elephant toothpaste: students used hydrogen peroxide, yeast, and dish soap. Yeast catalyzes the decomposition of the hydrogen peroxide into water and oxygen; when the reaction starts to foam, it looks like toothpaste squirting out of a tube.
