For an object slowing down, like a skateboard or a curling rock:

• What does the graph showing distance over time look like ?
• What does the graph showing speed over time look like?
• What does the graph showing kinetic energy over time look like?

• Done! I've built my street curling rock or freewheeling vehicle, or call it how you like!

• I have a starting line and a target.
• I can push my curling rock toward the target and trace a graph.

• I've changed my program to get my initial graph speed.
• I've tried a new push of my curling rock and I can log an approximate initial speed.

• My program is calculating and showing the kinetic energy at the beginning of my push.

• I've prepared the playing field.
• I've tried to hit the middle of the target 3 times.
• I've measured the distance between the target and where the rock stopped.

• I can answer these questions:
  • How would you summarize your experiment?
  • What have you learned?

Looking good!
