Materials
- Variety of items to show how light travels, such as glass, cellophane, sheer fabric, cardboard, etc.
What to do
1. Experiment with different objects to see which ones allow light to travel through them by holding them up to a window.
2. Talk about "transparent" it lets light shine through clearly; "translucent" it lets light shine through but less clearly; and "opaque" it does not let any light shine through at all.
