Light, color, and creativity come together beautifully in this hands-on Shape Suncatcher STEM Activity. Designed for curious young minds, this project helps children understand how light interacts with transparent materials while encouraging artistic expression and scientific thinking. It’s an ideal blend of art, science, and play-based learning . perfect for classrooms, homeschools, or outdoor exploration.
What Is a Shape Suncatcher?
A suncatcher is a colorful design made from transparent materials that “catches” sunlight and projects bright patterns when hung near a window or placed under natural light. In this version, children create suncatchers shaped like familiar 2D geometric figures—circles, squares, triangles, hearts, and more.
As sunlight shines through the colored shapes, it transforms into a glowing visual display, helping kids see science in action. The project encourages students to explore transparency, color mixing, and light behavior—key concepts in early STEM education.
STEM Concepts Behind the Activity
This activity introduces children to light transmission and transparency in a simple, hands-on way.
Here’s the science:
Light travels in straight lines and can pass through transparent materials like cellophane or plastic sheets. When sunlight passes through a colored transparent material, it filters the light—allowing only certain colors to pass through.
This filtering process changes the color of the light we see. It’s the same principle used in:
-
Stained glass windows in architecture
-
Magnifying glasses and microscopes in science tools
-
Sunglasses and lenses in everyday life
-
Raindrops creating rainbows in nature
Through observation and exploration, children begin to connect what they see in the classroom with the world around them.
Learning Objectives
By the end of this activity, students will be able to:
-
Understand that light can pass through transparent materials.
-
Identify and describe 2D shapes and their features.
-
Experiment with color and transparency to create glowing visual effects.
-
Observe, predict, and test how sunlight interacts with materials.
-
Strengthen fine motor skills through cutting, gluing, and coloring.
This activity integrates STEM, art, and fine motor development—making it a rich learning experience that sparks curiosity and creativity.
How to Use the Shape Suncatcher Pack
Preparation:
-
Print the templates on cardstock or paste them onto cardboard for durability.
-
Cut along the dotted lines to create the inner “window” of the shape.
-
Cover the cut-out area with colored cellophane or transparent craft paper.
Best Setting:
Place the finished suncatcher near a window or take the activity outdoors under sunlight for the best glowing effect.
Optional Extension:
Encourage children to layer different colors and predict what new shade will appear when sunlight passes through them. This adds an element of experimentation and critical thinking to the project.
STEM Reflection and Observation
To deepen understanding, children can use the included STEM Journal Page to record their observations.
Reflection prompts include:
-
What shape did you use?
-
What color did you see when light passed through?
-
Could light pass through it easily?
-
Where do you see this idea in real life?
-
What did you learn about light?
This reflection encourages scientific thinking — helping students connect theory with observation and build early inquiry skills.

Why This Activity Matters
1. Cognitive Growth:
Children explore cause and effect as they see how light changes when passing through colors.
2. Fine Motor Skills:
Cutting, gluing, and coloring improve hand–eye coordination and control.
3. Creativity and Expression:
Kids experiment with design, color combinations, and artistic arrangements.
4. Real-World Understanding:
They connect classroom learning to real-life examples like stained glass, lenses, and natural light phenomena.
This activity turns a simple art project into a meaningful science exploration that builds curiosity and confidence in young learners.
Teacher Tips
-
Print on sturdy cardstock for long-lasting use.
-
Laminate the templates for classroom reuse.
-
Encourage group work to develop teamwork and communication.
-
Display completed suncatchers on classroom windows to create a “STEM light gallery.”
-
Always conduct the final step under natural sunlight to let children truly see the magic of light and color.
The Shape Suncatcher STEM Activity is more than just a craft — it’s an early science experience that invites children to think, create, and explore like real scientists. By combining light, color, and creativity, students gain hands-on understanding of important STEM concepts while enjoying a visually stunning result they can proudly display.
