By constructing and testing a slingshot rocket, each student will experientially comprehend basic aerodynamic principles such as stability, drag, and lift. Redesigning the rocket after testing it offers students the opportunity to apply their newfound knowledge to create a higher performing rocket, which in turn promotes further insight into aerodynamics. Students will also gain an experiential understanding of fundamental physics principals as they launch their rockets, such as stored energy, trajectory, and Newton's laws of motion.

Lesson Plan
- State the name of the project and demonstrate how it is used.
- Build the project in front of the class. As you build, explain the function of each part of the rocket. The straw forms the body of the rocket, the fins provide stability, and the paperclip attaches the rocket to the slingshot.
- Explain how to launch the rocket. 1. Hold the slingshot straight up and in front of oneself. 2. Lower the bent paperclip onto the rubberband and pull back. 3. Hold the slingshot straight up and down, then pull back and release.
- Use thick milkshake straws if you can find them.
- The straw can shatter if the rocket is propelled directly into a hard surface. If you're launching in a confined space, wrap the entire straw in tape (do this carefully to avoid lumps and flaps that could create drag).
- Establish a 'firing range,' in which students all stand on one end of the room and fire in one direction only. After students retrieve their rocket they should swiftly move to the side of the range before returning to this firing line. Picking up the rocket and pivoting to face the firing line can result in a crash-landing into someone's face.
- Bring blocks, targets with point values, or any other creative addition to transform aimless shooting into a game of accuracy.
- Try it at home before you bring it to class :)
