General Questions

  • What requirements must be met?
  • 1. Has to run with no batteries (gravity powered)
  • 2. Has to travel at least 3 meters (break record of 6m)
  • 3. Use experiments to learn how to control the cruisers performance
  • 4. Design your teams new vehicle (with mechanics)
  • 5. Be ready to present/explain.
  • 6. Has to travel in a straight line.
  • 7. Sturdy enough so kids can play with it.
  • 8. Easy to repair.
  • 9. Eye catching appearance.
  • 10. Made from corrugated plastic, wheels and string.
  • 11. Powered by a lever and weight system.
  • 12. Adjustable so the person using it can make it go farther.
  • What do you need to learn in order to build your design?
  • The materials we need, how to design the cruiser, and how to make gravity power it.
  • How will you know if your toy design is successful?
  • It will get past 3 meters and will not break and if we make a mapped out blueprint clearly showing what we did and what we're going to do.
Build Knowledge
  • What are the basic parts to a Gravity Cruiser?
Lever and weights
Wheels and Axles.
  • How do these parts work together?
  • Build a model and then answer the following questions: Change parts of the model, record observations, and discuss your results with other teams.
Amount of pennies
Size of wheels
Location of lever compared to the fulcrum
Location of lever compared to the support beams
Length of lever
Length of axle
  • How does your model work?
  • How could you make it work better?

  • Make predictions on what parts allow your model to be a quality toy that meets all requirements
  • What ideas do you have for your design?
  • What will make your design stand out among all the other teams?
Build & Test
  • Build and test your design that meets the performance criteria
  • Redesign as time allows to create the optimal toy (Keep in mind the appearance of your cruiser)
  • Show and describe your work to an audience
