Students will design and build a crew exploration vehicle, or CEV, that will carry two cm-sized passengers safely and will fit within a certain volume (size limitation).
• Engage in the engineering design process.
• Design and build a model CEV within certain parameters.
• Test their vehicles using a drop test and revise their designs.

Lesson Activities and Sequence
Design a Crew Exploration Vehicle Educator Guide
- Introduce the challenge: NASA needs a vehicle to take people to the moon. The space shuttle cannot do that, because it was never designed to leave the Earth's orbit. The crew exploration vehicle must be designed to serve multiple functions and operate in a variety of environments (scripted in the activity guide).
- Brainstorm and design: Students should be working in cooperative groups to develop a group design and using individual journals to record their decisions, design sketches, test results, etc. You may also use the provided activity pages for student drawings.
- Build, test, evaluate and redesign: Each team should conduct two drop tests from about 1 meter. Test data, solutions, modifications, etc., should all be recorded in their journals individually.
- Discuss what happened: Ask the students to show each other their CEV and talk about how they solved any problems that came up.
- Evaluation: Using the students' journals, assess their mastery of content, skills and the engineering design process.
