🛞 E1 Push, Pull, Roll

Oh no! Every car in Prototype Workshop has lost its wheels, and the big parade is on Friday. The Mayor needs engineers who can make things roll.

Explorers, Foundation. Engineer Stamp: Wheel Wizard.

Lessons

  1. What makes a car roll?: Can just 13 pieces make a real car? Let’s find out!
  2. The push buggy: Prototype Workshop’s babies need a buggy. Who can build one that won’t wobble?
  3. Ramp races: Is a tall ramp or a low ramp better for racing? Guess with a thumbs up or down!
  4. The car that goes by itself: This car has a secret spring inside. Pull it back and… whoosh!
  5. Design Day: Stop on the line: The parade route ends at a flower bed. Cars that roll too far squash the flowers!
  6. Showcase: Prototype Workshop Grand Prix: Today is parade day! Every car gets three tries on the big ramp.

Design challenge

Build a car that rolls down a ramp and stops ON the finish line: not before, not after.
