HippoCampus Help
HippoCampus is a free online collection of video lessons, simulations, and interactive practice for high school and early college subjects such as algebra, calculus, biology, history, and English. Hosted by the NROC Project, a nonprofit focused on open education, it pulls materials from trusted sources including Khan Academy, PhET, and NROC’s own courses into a single organized portal. Users can browse by subject, textbook, or collection, making it easy to find an alternate explanation or extra practice on a specific concept. Families and teens use HippoCampus as a supplement to textbooks or online classes, especially when a student needs to see and hear a concept presented in a new way to make it click.
