How to make a Rainbow Sun Catcher for outdoors Shadow Art
Learn to make a Rainbow Sun Catcher Shadow Art With Your Kids. We will walk you through how to make this simple yet effective rainbow shadow art project.
First, take your cardboard and cut out the rainbow shape (use our template below for help if needed)
You do not have to make space for all seven colours of the rainbow, approximate is fine and as you can see even with four colors you will still create a perfect rainbow effect. Add more if you want to.
With four spaces, you can go for red – yellow – blue – purple.

Once you have cut out the cardboard outline for the rainbow, attach the colored cellophane into each space or window.
Do this by gluing the colors firmly onto the back of the cardboard. You can use a hot glue gun for a long lasting firm hold.
That’s all! Once the glue is dried, your stunning rainbow suncatcher is ready to take outside and play with. Isn’t it beautiful?

This fun activity is a great way to introduce kids to the concept of shadows and light, an early Science concept which helps them to build their understanding of the world around us.
Understanding Shadows and Light
When an object blocks the source of light, a shadow is formed.
Can the kids explain why the rainbow sun catcher allows the colors to be displayed on the ground? It’s because the cellophane is translucent, so some of the light passes through.
You can experiment with making another sun catcher using different materials like colored tissue paper (a tissue paper rainbow suncatcher is super cute to make to hang in the window) or experiment with rainbow colored liquid in bottles and compare the results.

Our main source of light is the sun. Let the kids experiment with their rainbow sun catcher and a torch and see if they can make some rainbow shadows indoors. Which light source works better?

Alternative Version
You can make a similar craft with just cardboard and a knife, if you don’t have colored cellophane to hand. Use the knife to cut out your child’s name, or different shapes and words to explore shadows in the sunlight.

You can also have fun playing with shadows and light making shapes with your own bodies. What else can the kids find to make shadows? They will be excited to try all kinds of different shapes and objects.
