On 10/17/17 we learned how to use clinometers to measure how high our rocket will go. We got into groups and Mrs. Boyer taught us how to use it. When you use a clinometer you have to hold it and the end and then hold it out in front of you so your arm is straight. When you measure something you pull the trigger and then move it up so the little hole on the top is pointed towards  the object. Once you get to it on it’s highest place you let the trigger go. In our case, someone threw a soccer ball in the air and one person in your group measured how high it went. I think clinometers are very cool, I think they are very fun to use.
