9 STEM Challenges

9 STEM Challenges

Challenge yourself to design the strongest bridge, the fastest balloon-powered car, the most protected egg drop or the paper airplane that flies the furthest with these STEM challenges! Put the engineering design process into practice as you apply STEM principles to rise up to the challenge! These projects are great for group STEM challenges, science fair projects, or even a weekend fun activity!

Paper Airplane Folds and Flight Distance
1. Paper Airplane Folds and Flight Distance
Fold paper airplanes with different designs and launch them to discover which shape flies the farthest.
Medium
Surface Tension and Water Strider Design
2. Surface Tension and Water Strider Design
Design a model insect from simple materials and see if you can make it stand on water using surface tension.
Medium
Egg Drop Survival Challenge
3. Egg Drop Survival Challenge
Design a protective case from household materials and find out whether your raw egg survives a high drop.
Medium
Balloon Power and Newton's Third Law
4. Balloon Power and Newton's Third Law
Tape a balloon to a Styrofoam car and watch Newton's Third Law launch it across the floor.
Medium
Suspension vs. Cable-Stayed Bridge Strength
5. Suspension vs. Cable-Stayed Bridge Strength
Build two bridge models from balsa wood and load them with weights to find which design is stronger.
Medium
Triangles vs. Squares in Bridge Strength
6. Triangles vs. Squares in Bridge Strength
Build two toothpick bridges from different shapes and load them with gravel to see which collapses first.
Medium
Bridge Strength Across Three Designs
7. Bridge Strength Across Three Designs
Build three bridges with different designs and test which one bends the least under a heavy load.
Medium
Parachute Shape and Drop Speed
8. Parachute Shape and Drop Speed
Drop four parachute shapes from a balcony and discover which one floats down the slowest.
Medium
Parachute Design and Air Resistance
9. Parachute Design and Air Resistance
Build a parachute from a plastic bag and see how trapped air slows a falling toy to a gentle float.
