Important Guidelines and Information:
Balloon Powered Car Project - this is an in-class project with a PowerPoint presentation.
Materials are gathered from home or wherever to build the balloon powered car. The goal is to
apply what has been learned about mechanical interactions by building a rocket car that
minimizes friction and drag. During testing, we will calculate average speed and take many
measurements. We then will analyze the interactions and forces involved in our cars. The most
challenging aspect of this project is being creative in both design and application. Another
challenge is the actual construction of the car. You will run in to some technical issues (car turns,
balloon drags on ground, parts fall off your car, or it just doesn't work at all!) that will require
additional work and planning.

Project Rules/Guidelines:
* You will be given one 9-inch balloon to power your car.
* The car must only be powered by one balloon.
* The car must be made from simple materials, nothing prefabricated.
* The car may not leave the ground and have at least 3 wheels
Car Testing:
* Pre-measure a distance of 5 meters.
* One car will race at a time. One team member prepares the car at the starting line.
* Cars take off at "Go!" Timers start.
* Time will be taken twice at 1m, 2m, 3m, 4m, 5m, and at car stop (total run time).
* Cars continue pass the finish line until they stop.
* Measure total distance traveled.
* Each car will be allowed three trial runs only if necessary. This allows a second or third
chance if the car turns, balloon pinches, etc. If the car makes a successful run, we will
only use this data.
* Grading for car performance: less than 1 meter: 0 points, 1 meter: 10 points, 2 meters:
20 points, 3 meters: 30 points, 4 meters: 40 points, 5 meters or more: 50 points.
