Since time immemorial we have used the Sun’s rays to warm ourselves during the day and the glow of a flame to light up our world at night. Today, we control the inter-conversion of ...
- Transparent, Translucent, or Opaque? In the Can You See Through Me? lesson, students experiment with materials to see how they absorb, scatter, transmit, or reflect light.
- Casting Shadows. What happens when you walk down the street and the sun is in front of you? A shadow appears behind you! Objects that block light cast shadows.
- Reflections in a Mirror. In the Mirror, Mirror on the Wall... lesson, students experiment to see how reflective surfaces like mirrors change the direction of light.
- Colors of a Rainbow. In the How Many Colors in a Rainbow? activity, students use a pan of water, the sun, and sheets of colored paper to create rainbows.
Dec 7, 2022 · Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength. The frequency of a wave is the number of crests (or troughs) that pass a point in one second.
