Directions
Tell children that they will be making as many shadows as they can using a paper plate.
- Give each child a paper plate and ask them to hold it in front of the lamp and make a shadow with it. Then ask,
- Describe the plate’s shadow. What does it look like?
- What size is the plate’s shadow? What shape is it?
- Then ask, How can you change the shadow that the plate is making?
- Encourage children to make as many different-shaped shadows as they can using their paper plate.
Write down how many different shapes children made—large, small, horizontal, vertical, wide, narrow, angled, etc.
