Curated OER
Wave Phenomena and the Electromagnetic Spectrum
Science learners scrutinize shadow size and quality, and experiment with diffraction. They model superposition of electromagnetic waves, and experiment with interference. These activities are action-packed and challenging for your...

Sometimes You Behave Like a WAVE, Sometimes You Don't!
Electromagnetic radiation behaves like both a wave and a particle. Help classes explore this concept through a lab investigation. Young scientists create optical interference patterns on a glass slide using a carbon layer. They analyze...
Curated OER
Electromagnetic and Physical Waves
Learners compare and contrast electromagnetic and physical waves. For this wave lesson, students discover that all waves reflect, refract, and diffract energy. Learners work in small groups to experiment with waves and evaluate the type...
Curated OER
The Grating Spectrometer; Light and Wavelengths
Students create a paper model that demonstrates wave interference for 3 wavelength from 2 sources. For this light and wave lesson, students use a real spectrometer and observe and measure the wavelength of spectral lines. Students then,...

Generation of Action Potentials in Nitella Giant Algal Cells
Learners observe cytoplasmic streaming in Nitella cells. They examine the conduction of a wave of depolarization across other membranes, such as the axons of neurons. Students predict the effects of sending a small electric current...
