This is a great hands-on project when you are teaching a unit on standard deviation. This project also incorporates charting, graphing, finding the mean, and measuring. The project is designed like this: The class will split into groups of three, each person in the group will construct their own paper airplane. You will then take turns throwing your paper airplanes and measuring the flight distance. Each person in the group will throw there paper airplane ten times and will chart the distance it flew (Round to the nearest inch). Groups will then graph the average distance for each of the three paper airplanes. Groups will then take the standard deviation of each airplane and decide on which one is the most consistent, flew the farthest, and has the highest average distance.
