STEM Outdoor Activity: Robot Suncatcher Craft

Robot Suncatcher STEM Activity for Kids

Looking for a fun outdoor STEM project that blends science, creativity, and hands-on learning?
Our Robot Suncatcher Craft is a classroom favorite! Students used cardboard and colorful cellophane to build bright robots that transform sunlight into glowing rainbow reflections.
It’s a perfect mix of art, engineering, and science — encouraging kids to explore light, color, and design in a playful way.

We recently did this Robot Suncatcher Activity with our Grade 6 to 8 students, and it was an absolute hit! 

Kids were amazed to see how the sunlight passed through the colorful cellophane and created rainbow robot shadows on the ground. It was a perfect mix of science, art, and creativity — and such a fun way to learn outdoors! 

This activity helps students explore how light passes through transparent materials, how colors mix, and how shapes reflect — all while designing and building their own robot model. It’s hands-on, engaging, and full of “wow” moments!
