The Amoeba Sisters YouTube Videos
Rating

The Amoeba Sisters strive to facilitate curiosity and engagement by making biology both humorous and meaningful. The videos use real world examples and silly cartoons to demystify difficult biology concepts, such as cell anatomy, homeostasis, enzymes, and biomolecules. A new video is released weekly. The creators are sisters who both work in education. One is a high school biology teacher who found these videos made biology more approachable and easier to comprehend.
