I'm So Bright, I Wear My Shades Indoors
Students observe and draw energy using UV beads. They describe how light can be produced, reflected, refracted, and separated into visible light of various colors.
Curated OER
Reflection
Students examine how some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.
