You will need a sunny day and access to water for this activity.
We recommend students work in groups of four. Homeschool students can work on their own.
This video shows how to set up a cup of water so that sunlight passing through the water separates into rainbow colors.
Make sure that your chosen location will be sunny at the time of day that you plan to do the activity.
If you are working with a class, make sure each group will have space for their own glass. If you can’t find a place that will accommodate students working in groups, you can opt to do the activity as a demonstration and encourage students to try it at home.
Before you try this with a class, do a trial run in your chosen location or in another sunny spot.
