Curated OER
Electromagnetic and Physical Waves
Students compare and contrast electromagnetic and physical waves. In this wave lesson, students discover that all waves reflect, refract, and diffract energy. Students work in small groups to experiment with waves and evaluate the type...
Curated OER
Electromagnetic Radiation
Young scholars explore the nature of electromagnetic spectrum through a series of experiments. In this physics lesson, students determine how light behaves under certain circumstances. They explain how humans perceive colors.
