Examples of light creating colors in nature for kids

📚 Quick Study Guide

• 🌈 Light is part of the electromagnetic spectrum. Visible light is the portion we can see, which consists of different wavelengths that we perceive as colors.
• 🍎 Color in nature often results from the interaction of light with different substances. Some materials absorb certain wavelengths and reflect others, resulting in what we see as color.
• 🦋 Iridescence is a phenomenon where colors change depending on the angle of viewing due to the structure of the surface, such as in butterfly wings.
• 🌿 Pigments are substances that give materials color by selectively absorbing and reflecting light. Chlorophyll, for instance, gives plants their green color.
• ✨ Bioluminescence is the production and emission of light by a living organism. It involves chemical reactions, often using luciferase enzymes.
