I halve problems.
My 4H Rocket Science group launch January 2007
We had a lot of fun that day, and only lost one rocket!
I was a 4H leader teaching Rocket Science to a great
bunch of kids.
I was able to teach them the physics of rocket flight using all the basic ideas I learned when I was a kid.
For example you don't need a wind tunnel to test aerodynamics or stability, you just need to use the old 'swing-test'.
That's the method of tying a string to the CG (center of gravity) of your model and then swinging it around in a big circle and watching what happens, if your nose cone stays pointed ahead, and it doesn't wobble, then you have a stable rocket.
I taught them strong gluing techniques, and how to correctly use a can of spray paint to get a nice smooth finish.
l taught them how to read an engine thrust-curve, so they would learn how to predict the flight characteristics of their model before they actually flew it.
In the video above we placed an 'A' engine in a 'B' or 'C' powered rocket design. It didn't go very high but they learned that they could use a undersized engine for flight testing, and could still have fun without losing a rocket in high wind situations.
I love kids, and I love to share my love of science and math with them, they won't shy away from learning if presented to them in an enjoyable manner.
