Light and Energy
Last week we held a prism in front of the window to reveal the different colors of light that are in white light. We read about the waves that make up sound and light, and learned that different colors of light in the rainbows are made by light waves of varying length and speed, with red having the longest, slowest wave, and blue the shortest and fastest.
This week we reviewed some of what we have learned this spring. Following Experiment 10 in our lab book, we played with physics, and revisited gravitational stored energy, mass, and inertia. We built card houses, and knocked them down with marbles. We also used watercolors to express the relationship between color and light waves.
