Pop quiz: What’s a 3D object with identical ends and parallel sides? A prism! Significant scientific discoveries have been made using prisms. For example, prisms helped demonstrate that white light is made up of the colors of the rainbow! The geometric properties of prisms are also important to understand, as these shapes are used to make various technology, including telescopes and microscopes. This list of 20 engaging prism activities is designed to get your students excited about the prism’s light-bending and geometrical properties!
Science Activities
1. Watch The Dr. Binocs Show
This animated video provides a thorough, kid-friendly explanation of what a prism is and how it can bend light to make a rainbow display. You can show this video to your kids as a short introduction to prisms.

2. Watch Teacher Freddie
Here’s another video explanation of prisms and how they can produce rainbow patterns. This video also describes how the process that creates rainbows from prisms (light refraction) is the same as what happens when rainbows are created in the sky after rainfall.

7. Homemade Prism with Glass
Here’s another homemade prism for your little ones to create. Your students can cut a hole into a piece of cardboard and place it near a glass of water. They must place these elements in such a way that the sunlight passes through the hole into the glass. They can then place a piece of white paper down to observe the rainbow pattern.
