Physics is about studying how the universe works, and since you're in it, it's really about understanding you and the world you live in. Hopefully you'll find this very interesting!

ROCKETS (with EGGs)

Why does an egg crack if you drop it? (off our balcony ~ 5m)
How could you prevent the egg from cracking?

OK, now let's have some fun getting that contraption 5m high :-)

Can you make a rocket that carries an egg at least 5m high and brings it back down without cracking it?
The launch date is Friday December 6th!

You can use up to a "C" level engine (see below), but no kits!!!
Eggs will be provided on launch day (puhleesse don't bring your own!!!)

Deepen your thinking - how does this project involve Newton's 3rd, 2nd, and 1st laws, as well as the conservation of momentum (and this whole impulse concept?)  Use physics to engineer your way through this conundrum!

Oh, and think about how this could be connected to terminal velocity, balanced forces, etc. etc. etc.



Details:
Use a "C" engine.  Yes, there's lots of different kinds of "C" engines, you're probably going to want to learn a bit about them so you can make an informed choice.  If you're new to rockets, you may want to start at Wikipedia.

If you want to buy your own, check out Amazon or Rocket"R"us
or go to Hobby Lobby or some such local store.  I'll have some available in class at cost too (first come first served!)  Here's a listing of local Hobby Lobby stores - but try searching for other model rocket stores too!



The launcher platform and ignition box will be provided, you'll need your own rocket, engine, igniter, and plug.  and yes, we'll be wearing goggles for this one!  Friday 12/6/2013 = launch date!
