Safety notes
No special safety concerns. Ensure the area is well-lit and free from hazards.
What you will need
- Clear glass
- water
- white paper
- flashlight
Step-by-step instructions
- Gather Supplies: Collect a clear glass, water, white paper, and a flashlight.
- Fill the Glass: Fill the clear glass with water until it is about three-quarters full.
- Set Up the White Paper: Place the white paper on a flat surface where light can be directed onto it.
- Position the Flashlight: Hold the flashlight at an angle behind the glass, directing the beam through the water.
- Observe the Rainbow: Watch and adjust the angle of the flashlight until a rainbow appears on the white paper.
- Discuss the Science: Talk about how light bends and creates colors as a family. Ask questions to encourage critical thinking.
Parent guide
Encourage your child to experiment with different angles of light and distances. Discuss what they observe to deepen their understanding of the concepts. Ask them to predict what will happen before making adjustments to the flashlight.
