I'm a ROCKET SCIENTIST
Last time in STEAM, we learned about rockets and then got to work making our own and launching them.
How does a
rocket work?
Have you noticed what happens if you
let the air out of a balloon? The air
goes one way and the balloon moves in the opposite direction. Rockets work in
much the same way. Exhaust gases coming out of the engine nozzle at high speed
push the rocket forward.
Rockets need so much fuel in order to overcome Earth’s
gravity. Only when they reach a speed of 17398.393 miles/hr. are they traveling fast enough to enter orbit. Take some time to - Watch this video to see how real rockets work
Most rockets are made up of two or three stages. When a stage has used up all of its fuel, it is separated to get rid of the dead weight. It then falls back (usually into the ocean and far from populated areas) or burns up in the atmosphere.

An important part of a Science Experiment is the
Scientific Method
Be sure the answer these questions as you do your experiment
Set up a balloon rocket course in a room and began testing
out different sized balloons. Test round balloons and narrow balloons, being sure to use the same amount of air in each. Measure after each flight and keep notes on
each distance. After all the balloon flying, get to the final step. Looked at all the data from the experiment to
figure out if the hypothesis was correct. So which kind of balloon traveled the
farthest?
