Funbrain offers hundreds of games, videos and books for pre-k through 8th grade levels. Activities are designed for at home or at school.
We found this cool Coral Reef game that allows you to explore underwater to learn about sharks, octopuses, sea turtles, jellyfish, and more.
Activities have supplemental materials to help further learning. There is also a 30-day free trial of Science Simulations available.
