Have a group discussion on how to go about solving the problem. Once the class has established a method or process for solving the design problem, review the Student Guidesheet with them. Emphasize that each student pair must document their problem solving process and keep a record of their observations, modifications, observations and possible solutions. Allow time for them to learn about the principles of flight and then use that knowledge to experiment on their airplane design. Set periodic time limits in order to facilitate the gathering of design information that will be compiled and used during the online collaboration periods.
