Pupils apply their knowledge of refraction to four different sets of challenges. Each of the first three focus on one variable's impact on the direction of bending. The fourth combines variables for greater challenge.

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....

How do jewelers tell the difference between diamonds, glass, and cubic zirconia? A sparkling simulation demonstrates how to use a ray of light to determine the substance and ideal shape for a diamond. Scholars control the material,...

How did scientists discover what lies beneath the earth's surface? Dig a hole? X-ray vision? Guide your class through the types of seismic waves and how these waves helped shed light on Earth's many layers. The included resources provide...

Third graders observe light as a form of energy, that it can be reflected/bounced, refracted/bent and absorbed. They explore how different types of light affect our lives as a whole. Songs are researched that involve light (ex. "You...
