All supplies need to be available for each group.
2-liter soft drink bottle
1-liter water bottle
One 1-inch-long by ¾-inch-diameter PVC segment
Aluminum soft drink can
Scrap cardboard, poster board and tag board
Large cardboard panels (about 3 by 1 foot) for silhouettes
Low-temperature glue gun
Plastic grocery bag or garbage bag
The following are needed for launch day:
Water rocket launcher (see page 109)
Altitude tracker (see page 80)
Teams of students will form "rocket companies" and compete in a commercial endeavor to construct a rocket capable of lifting payloads into Earth orbit. Through a strong interdisciplinary approach, balancing science with technology, engineering and mathematics, they will develop a budget, purchase construction materials and track expenditures while designing the rocket.
• Apply rocketry principles and design, construct, test and launch a water rocket using a real-world problem-solving simulation.

Lesson Activities and Sequence
Rocket Activity Project X-51
- Write a Request for Proposal. Form a rocket company. Pick company officers. Brainstorm ideas for design and budget. Sketch a preliminary rocket.
- Using graph paper, draw side, top and bottom views of your rocket to scale (1 square = 2 cm) based on the measurements recorded above. Attach your drawings to this paper. If you make changes during construction, your scale drawing and measurement sheet should reflect them.
- Develop a budget for the project and stay within the allotted funds.
- Build a test rocket using the budget and plans developed by your team. List rocket specifications and evaluate your rocket's stability by determining its center of mass and center of pressure and by conducting a string test.
- Successfully test launch your rocket with a 250-gram payload of simulated fuel.
- Develop a cost analysis for your vehicle and demonstrate the most economically efficient launch.
