Week 4: Introduction to hobby motors and hobby rocket kit

We started getting the students acquainted with the kits they will be using and the engines that will power their rockets.   We went through the engine designations and touched on what thrust and total impulse are.  Thrust is the measure of the force the rocket provides to lift itself off the ground and total impulse is the measure of the rocket engine's thrust multiplied by the total time it burns.  We lit a small engine on the ground to give the students a little show.  That thing was a site to see!  After that the students got to open their rocket kits and start dry fitting the pieces together.  I am looking forward to building these hobby rockets and flying them.
