What’s the Difference Between Brain Surgery and Rocket Science? One of these activities we can do in middle school, and one we can’t!!! One of these activities we can do in middle school, and one we can’t!!! Brain Surgery? Brain Surgery? NO!! NO!! Rocket Science? Rocket Science? YES!!! YES!!!

Introduction Have you ever seen a space rocket launch? Have you ever seen a space rocket launch? Didn’t you wonder how it worked? Didn’t you wonder how it worked? You may even have thought “I want to do that” You may even have thought “I want to do that”

Task In this assignment we will be investigating Rocketry and building our own re-usable rocket (max uses) In this assignment we will be investigating Rocketry and building our own re-usable rocket (max uses) Rocket bodies will be plastic soda bottle (s) Rocket bodies will be plastic soda bottle (s) Rocket fuel will be compressed air and water Rocket fuel will be compressed air and water

Process We will make informed decisions regarding building our rocket after gathering information from the Internet. We will first look at: Rocket historyRocket history What are soda bottle rocketsWhat are soda bottle rockets Physics behind soda bottle rocketsPhysics behind soda bottle rockets Safety with rocketsSafety with rockets Parts of a soda bottle rocketParts of a soda bottle rocket Designs for a soda bottle rocketDesigns for a soda bottle rocket
