9. When the rockets have been completed, have teams qualify their rockets for flight by conducting string tests. Using several feet of string, tie the rocket around the middle so that it balances. Because of the nose cone weight, the balance point will be towards the nose. When the rocket hangs level, a small piece of tape should be temporarily fixed to the string and bottle to keep the string from slipping. The rocket is then twirled in a circle. If the rocket tumbles while circling, it is not stable and needs more nose cone weight, bigger fins, or a combination of both. If the rocket circles with the nose always pointed forward, it is stable and ready for flight. (More information about string tests will be found in the instructions for Project X-51.) 10. Review launch procedures with the teams. The instructions are outlined in the activity for constructing a water rocket launcher (see page 109). Conduct an inspection the day before the launch to ensure that rocket fins are securely attached. 11. Set up a tracking station for measuring the altitudes achieved by the rockets. Follow all safety procedures and instructions when launching the team rockets. Assessment • Inspect each team’s rocket for the construction skill employed. Fins should be vertical and securely attached. The rocket should be stable. • Observe the flights and note how the recovery system designed by teams worked. Extensions • Conduct a space art show to feature decorating schemes of team rockets. Have students draw artist’s conceptions of their rockets in flight. (See The Art of Spaceflight on page 146). To view artist’s conceptions of NASA’s new Constellation program, see pages 13-17. Clear an open space for swing tests. 117
