Lesson Activities and Sequence
The suggested sequence is to start with simple detection of light through passive sensing and then demonstrate the differences in knowledge gained by using different light sources.
- Amazing Rays
Students explore light and heat as different components of the sun’s energy using photo reactive paper as a passive sensor.
Keywords: reflection, refraction, diffraction, medium, passive detection, waves, light, magnifier
- Investigating Ice Worlds
Students use various light sources to examine ice and understand how NASA studies planets and moons from space.
Keywords: spectrum, magnetic, electrons, color, light
