Engineers solve problems. They build, test, fail, and build again. These challenges are designed to test your structural skills, creativity, and patience. Are you ready to think like an engineer?
1. The Indestructible Egg Drop 🥚
Can you protect a fragile raw egg from a high fall? This classic physics challenge teaches about gravity, drag, and impact handling.
The Challenge:
Design a container that prevents a raw egg from breaking when dropped from a height (like standing on a chair or a balcony—with adult supervision!)
Allowed Materials:
- Straws & Popsicle sticks
- Tape & Glue
- Cardboard / Paper
- Cotton balls / Bubble wrap
- Plastic bags (for parachutes)
Engineering Tip: Think about two things: Slowing down the fall (air resistance) and cushioning the landing (shock absorption). A parachute helps with the first, and a soft padded box helps with the second!
2. The Spaghetti Bridge Challenge 🍝
Spaghetti is brittle and snaps easily. But if you use geometry, it can hold amazing weight!
The Challenge:
Build a bridge that spans a 30cm gap between two tables. See how many coins or small toys it can hold before breaking.
Allowed Materials:
- Dry Spaghetti
- Marshmallows or Tape (to join joints)
Engineering Tip: Triangles are the strongest shape! Squares collapse easily under pressure, but triangles distribute weight evenly. Try incorporate trusses (triangles) into your bridge design.
3. Paper Helicopters (Rotocopters) 🚁
Explore aerodynamics with nothing but paper and a paperclip.
The Challenge:
Build a paper helicopter that stays in the air the longest and spins the fastest.
The Build:
- Cut a strip of paper (about 5cm x 20cm).
- Cut a slit halfway down the middle of the strip to make two “ears” (these are the blades).
- Fold one ear forward and one backward.
- Add a paperclip to the bottom for weight.
- Drop it and watch it spin!
Experiment: What happens if you make the blades shorter? Longer? Add more paperclips? Record your results just like a real scientist!
