  1. 2 · The chart shows 2 misses. Count the miss bar to check.
  2. Try it and watch what happens · Testing means trying your design first, so you can see what really happens.
  3. False · Missing every time means the design still needs changes.
  4. Make the ramp shorter or lower · A shorter or lower ramp can make the ball go a shorter distance.
  5. Look at the data and change something · The data shows it mostly did not work, so Zoe should change her design.
  6. Ramp A · Ramp A hit the cup more times, so its data shows it worked better.
  7. Yes, the change made it work better · More hits after the change means the change made the design better.
  8. He should test more times before deciding · One test is not enough. Testing many times gives better data.
