Four Simple STEM Activities for Kids

Make it easy for kids to learn about STEM with these fun activities.

It’s never too early to introduce STEM (science, technology, engineering or math) to young children. Here are four simple hands-on activities to show kids of all ages just how fun STEM can be. 

STEM Activities

Activity #1: Spaghetti & Marshmallow Tower  

Goal: Design and build a tower as high as possible using only spaghetti and marshmallows. The tallest tower within the allowed timeframe that stands on its own wins. 

 

This activity encourages kids to think about design and basic engineering principles.  

STEM Activities

Activity #2: Paper Roller Coaster 

Goal: Design and build a paper roller coaster at least 24 inches tall, with at least two turns using paper or cardboard tubes and tape. A marble should be able to roll from top to bottom without stopping.  

 

This activity introduces the concept of physics, gravity and motion as the marble rolls down the track from the top of the roller coaster. 

STEM Activities

Activity #3: Magnetic Slime 

Goal: Make magnetic slime with glue, liquid starch and iron oxide powder and feel the power in the pull between the magnet and slime.  

 

This activity is all about chemistry – the states of matter including liquids, solids and gases.  

STEM Activities

Activity #4: Potato Power

Goal: Create potato power by lighting a small LED light bulb using potatoes, pennies, galvanized nails, insulated wires with alligator clips and a multimeter. 

 

This activity demonstrates how electricity is produced. The potato battery works in a simple circuit to generate electrical energy.
