Have you ever watched a rocket launch on TV
or online? Have you noticed how some parts of the rocket
seem to fall away in the middle of the flight? Like in this video from an on-board camera
when NASA’s Juno spacecraft was launched on its way to Jupiter, this video of SpaceX’s
Falcon 9 rocket, or this video from the space shuttle Endeavor? In this activity you will learn how rockets
use multiple stages to save energy when launching payloads into space, and build your own model
rocket out of balloons that you can launch across your classroom.
