Objects That Block Light: Examples and Activities for Kids

📚 Quick Study Guide

• ☀️ Light Sources: Objects that produce their own light (e.g., the Sun, a lamp).
• 🔦 Transparent Objects: Allow almost all light to pass through (e.g., clear glass, water). You can see clearly through them.
• 🌫️ Translucent Objects: Allow some light to pass through, but not all (e.g., frosted glass, thin paper). Objects appear blurry.
• 🧱 Opaque Objects: Block all light from passing through (e.g., a brick, a book). You cannot see through them.
• 🌑 Shadows: Formed when an opaque object blocks light. The shape of the shadow depends on the shape of the object and the position of the light source.
