1. The document describes several experiments involving light and color, including using a spinning color wheel or prism to demonstrate that white light is composed of the visible color spectrum. 2. One experiment uses colored paper to show that black absorbs the most heat from a light source, while white reflects the most heat. 3. Another experiment uses a prism or water glass to separate white light into a rainbow spectrum, and then uses a magnifying glass to recombine the colors into white light.
