The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinkys certification and experience in teaching science at the high school level. Pinkys teacher certification is in grades 4-8 science and 8-12 composite science (encompassing biology, chemistry, and physics). Amoeba Sisters videos only cover concepts that Pinky is certified to teach, and they focus on her specialty: secondary life science. For more information about The Amoeba Sisters, visit: \r
