The Legendary Raptors
How are raptors and airplanes alike? Combine science and language arts in this fun and interactive project. Young scientists research the animal in order to design their own aircraft, and compete in a contest for farthest, fastest, and...
PHET
Bending Light
Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....
