Science Experiment: Making Light Bounce

Looking for a hands-on experiment that teaches children how light travels? If so, you’ve come to the right place. I’m working with to bring you a quick and simple science project that shows your kiddos how to make light bounce. This experiment will go great with a unit study on the properties of light, as an invitation to play prompt, or just as something new to try on a rainy day.
Below, you’ll find all you’ll need to know to make this project happen. All of materials are typically found around the house because yeah, that’s the only way science projects happen in here, too. Hope you enjoy!
Making lightbounce


  • How does light travel?
  • What happens to the path of light when it hits an object?
  • How can light be reflected?

Light travels in a straight line.It continues in that straight line until it hits another object. The light then can be absorbed, refracted, or reflected.A shiny object such as a mirror can be used to redirect light from its source to another location through reflection.


  • 3 or more mirrors
  • Flashlight (This should be strong flashlight, like a MagLite.)
  • Book


  1. Dim the lights in the room so that the light from your flashlight will show well during this experiment.
  2. Set up a book on a table so that it’s standing. Point your flashlight at the front side of the book. What happened to the beam of light? Draw an illustration.
  3. Lean a mirror against the front of the book so that it’s standing. Point the flashlight at the mirror and turn it on. What happened to the beam of light? Draw an illustration.
  4. Have an adult or friend help you use 2-3 more mirrors to direct the flashlight beam to the backside of the book through reflection. Try many different ways to do this. Draw diagrams of each path you create to reflect the light to the back of the book.

Terms/Concepts: Light; Absorption; Refraction; Reflection
