Exploring the Colors of the Rainbow Through Hands-On Activities
Engage students in an interactive lesson about rainbows, colors, and light by introducing them to the concept through real-world examples. From observing rainbows in various settings to hands-on experiments creating color wheels, this session aims to deepen understanding of the science behind the vibrant spectrum of colors. Students will enjoy activities such as using rainbow glasses and CDs to explore light refraction, mixing primary colors to form secondary hues, and experimenting with color combinations. By the end, students will have a newfound appreciation for the magic of rainbows and the colorful world around them.
