When you are using a new tool, like an inclinometer, different people will come up with different estimates. Averaging these measurements improves the accuracy of your results.

If they do, we suggest that you spend another session trying to improve rocket designs. You might want to talk with your group about what changes might make a rocket fly better. Here are some things you might want to encourage them to think about. To move through the air, a rocket has to push air aside.
