Discussion Prompts

Observing

  • What was the purpose of the investigation? 
  • What happened to the car when the rubber band was pulled and released? What effect did that force have on the Spring Car?
  • How was the motion of the object observed and recorded?
  • How does the data show that the wheel and axle made the Spring Car’s work easier by reducing the amount of force needed to move the car? 
     

Predicting

  • How does a wheel and axle make work easier?
  • Based on what you’ve learned, is an object without a wheel and axle going to roll as far as an object with wheels and an axle? Why or why not?

Collaborating

  • What worked well in your team? 
  • What challenges, if any, did you face? 
  • What would you change for next time?
