Think Like an Engineer

Engineering challenges teach kids to plan, build, test, and iterate — the core design process. Use cheap materials so failure is low-stakes and rebuilding is encouraged.

Challenge 1: Spaghetti Bridge

Build a bridge from dry spaghetti and marshmallows that supports a cup of pennies. Teaches load distribution and triangular structures.

Challenge 2: Paper Tower

Build the tallest free-standing tower using only 10 sheets of paper and tape. Explores structural stability and center of gravity.

Challenge 3: Egg Carton Catapult

Design a catapult from an egg carton and rubber bands. Launch pom-poms at targets. Teaches stored energy, leverage, and trajectory.
