Use the basic STEM principles when designing your own paper airplane. You could add to this activity by researching the four factors of flight and tried and true paper airplane designs before you begin. Then, have a class competition! I put my students in groups of 2-3. They come up with a group name. After they have developed their "winning" design, we go to an open space in the school and launch the competition. You will be surprised how many school personnel will come out of the woodwork and become part of the competition! After the competition, students use their math skills to graph the results and calculate the mean, median, mode and range of the set of final numbers. SO FUN!
