Students will observe the launch of their hot-air balloon. Upon completion of all launches, students will evaluate and critique their design and suggest possible improvements to the construction.

Time Required

Two (or Three) 90 minute class periods (Four or five 45 minute class periods). Time will depend on number of groups that launch.

Pre-Requisite Skills

Student groups should have already built a hot-air balloon for launch during this lesson.

A digital camera will be used to take pictures of the different balloons in flight (or not). For the balloon evaluation, students will need computers with Microsoft Word or PowerPoint, and Computer & LCD projector for presentations to the class.

Mass for the "payload" of the balloons (we chose a 50 g mass).

Procedure

1. You will need an open area in which to launch the individual balloons.
2. Use your heating source to begin launching the balloons.
3. Have students take pictures of the balloons in flight.
4. Upon completion, return to the classroom and have students begin reflecting on the performance of their balloon.
5. Students will use computers with Microsoft PowerPoint to make a presentation to the class as to the success or shortcomings of their design, along with suggestions for improvements.

Peer tutoring/teaching may be used for students to investigate and discuss their performance in the launch.

The culmination of this unit could lead into a Social Studies discussion of the history of flight and the development of technology. An English teacher would be useful in assessing the final project of student work.

If students/time does not allow for a PowerPoint presentation before the class, have student groups write a one-page summary about the performance of their design.
