Introduction
Shadows don’t have to be black and white. In this colorful shadow STEM activity, children use translucent Lucite Cubes to explore how light, transparency, and overlapping colors create vibrant shadow art.
This hands-on experiment blends science and creativity — making it a perfect STEAM activity for curious preschool and elementary learners.
Age Range
3–8 years (with supervision when using flashlights)
Skills Developed
-
Understanding light and shadow
-
Exploring transparency and opacity
-
Color blending
-
Creative expression
-
Observation and experimentation
Materials Needed
-
Lucite Cubes (available with our block sets Riley Blocks, Barca Blocks, James Blocks, Noa Blocks, Austin Blocks and Millie Blocks)
-
Flashlight or strong directed light source
-
White wall, poster board, or large sheet of paper
-
Crayons or markers (optional for tracing)
Step-by-Step Instructions
Step 1: Set Up Your Shadow Space
Dim the room slightly for better visibility.
Place the white paper or poster board against a wall or flat surface.
Step 2: Shine the Light
Stack or arrange Lucite Cubes in front of the light source.
Shine the flashlight through the blocks toward the white surface.
Observe how the shadows appear.
Step 3: Explore Color Overlap
Layer two or more cubes in front of the light.
Watch how overlapping colors create new shades.
Ask:
-
“What color do you see now?”
-
“What happens if we move the light closer?”
-
“Does the shadow change if we tilt the block?”

Step 4: Turn It Into Shadow Art
Encourage children to:
-
Trace the colorful shadows
-
Draw around the shapes
-
Create patterns
-
Take photos of their designs
This turns a science experiment into a creative art project.
STEM Learning Concepts
Transparency & Opacity
Translucent materials allow light to pass through, creating colored shadows.
Color Blending
When colored light overlaps, it forms new hues.
Light & Shadow
Children observe how distance and angle affect shadow size and intensity.
Extend the Activity
-
Use natural sunlight instead of a flashlight
-
Experiment with distance to see how shadows grow or shrink
-
Try adding mirrors for more complex reflections
-
Create a “shadow gallery” wall


Why Shadow Play Matters
Shadow exploration builds early physics understanding while encouraging artistic experimentation.
Open-ended materials like Lucite Cubes allow children to explore abstract scientific concepts in a concrete, visual way — blending STEM and art seamlessly.
