BrainPOP is a group of educational websites with hundreds of short (5 minutes or shorter) Flash-based movies for students in grades K-12 (ages 6 to 17) covering the subjects of science, mathematics, engineering and technology, arts and music, health, social studies, and English. BrainPOP movies may be used to introduce a new lesson or topic, for illustrating complex subject matter or to review before a test. Content is aligned to USA state education standards and is searchable. In addition to movies, the site displays quizzes, games, experiments and other related content that students can use interactively to reinforce the lessons in the movies. BrainPOP products are compatible with PCs, Macs, projectors and interactive whiteboards. No downloading, installation or special hardware is required.
