Rocket Science? Rocket Science? One of these activities we can do in One of these activities we can do in
middle school, and one we can’t!!!middle school, and one we can’t!!! Brain Surgery? Brain Surgery? NO!!NO!! Rocket Science? Rocket Science? YES!!!YES!!!
IntroductionIntroduction
Have you ever Have you ever seen a space seen a space rocket launch?rocket launch?
Didn’t you wonder Didn’t you wonder how it worked?how it worked?
You may even You may even have thought “I have thought “I want to do that”want to do that”
TaskTask
In this assignment we will be In this assignment we will be investigating Rocketry and investigating Rocketry and building our own re-usable rocket building our own re-usable rocket (max 10-15 uses)(max 10-15 uses)
Rocket bodies will be plastic Rocket bodies will be plastic soda bottle (s)soda bottle (s)
Rocket fuel will be compressed Rocket fuel will be compressed air and waterair and water
