Students build their own spectrophotometer to study light. In this physics lesson plan, students explain the dual nature of light. They calculate the angle of incidence and refraction using Snell's law equation.

Students investigate lenses and mirrors showing how they bend and reflect light waves.

Students construct an interferometer using a simple telescope. In this physics lesson, students explain how light waves create the fringe patterns. They observe patterns made by different objects in the sky and compare them.

Students measure angles of refraction as the light travels through gelatin.  In this experimental lesson students complete a refraction lab and plot their data.

Students identify the challenges encountered by astronauts in operating a planetary rover. In this space science lesson, students create a rover using their team members. They follow a command sequence from the driver and navigate...

Students analyze the optical region of the electromagnetic spectrum.

Students investigate the refraction properties of gelatin to calculate its index of refraction. They discover that as the light travels through the gelatin, its speed and wavelength also change. Students find th indes of refraction of an...

Students explore how a battery-powered light box demonstrates how to transmi timages.

Students interpret a message sent to space using a radio telescope and draw inferences from the interpreted message. Working with a partner, they interpret data that scientists believe is a message from aliens. They work on organizing...

Students describe what scientists mean by an "expanding universe" in their own words. They explain how scientists comprehend the universie is expanding. Students comprehend the vast scale of the universe. They comprehend how theory...
