Age Range: 5–12 years
Difficulty: Medium
Description:
This sweet and simple STEM activity challenges kids to build their own towers using just marshmallows and toothpicks. It’s a hands-on way to explore engineering, design, and problem-solving.
What You'll Need:
-
Mini marshmallows (or gumdrops)
-
Toothpicks
-
A flat surface
Instructions:
1. Start by connecting marshmallows with toothpicks to form simple shapes like squares and triangles.
2. Challenge your child to build a structure as tall as possible without it falling over.
3. Try building different shapes—can they make a cube? A pyramid? A bridge?
4. Compare the strength and stability of each shape.
Educational Angle:
This activity introduces basic engineering principles, such as stability, symmetry, and structural design. Kids also practice fine motor skills, spatial reasoning, and critical thinking as they test different designs and solve problems creatively.
Tips for Grown-Ups:
-
Use this as a friendly family competition—who can build the tallest or strongest tower?
-
Talk about how real buildings use triangles and strong shapes in their design.
-
For older kids, introduce terms like “load-bearing,” “foundation,” or “architecture.”
