From memory, so if I screw things up forgive me as I don't have the syllabus in front of me....
Day 1 - General introduction and history of rocket development. Pretty boring day but it's amazing how ignorant the kids are. They actually have a sizeable piece of SpaceShip2 wreckage in their classroom but very few of them know what SpaceShip2 is/was! They just walk by this 3' long piece of plane wreck every day and are oblivious to it.
Day 2 - Covers the theory of how rockets work. Basic momentum balance stuff that they should already know if they were paying attention earlier in the year.
Day 3 - Discussion of Day 4's events: Static firing of rocket motors to measure the delivered thrust/time curve accompanied by an in-depth discussion of what those results mean in the real world. I also throw in discussion of what makes a good rocket propellant or not and actually mix an analogue of the propellant that was in the old Space Shuttle solid boosters (AP+Al+PBAN). Walk outside and burn the propellant at the end of the day.
Day 4 - Perform static firing of rocket motors. Each team fires three motors. Those teams that are not actively firing motors get to start building Estes Alpha rockets (this is what showed up on somebody's desk 8 years later!).
Day 5 - Introduce kids to Excel and let them finish building rockets.
Day 6 - Build a 1 dimensional flight simulation in Excel using the data obtained on Day 4. Output of simulation is max acceleration, velocity, altitude, time of flight...blah blah blah.
Day 7 - Finish up simulations, plot out results. Talk about stuff they're seeing in the plots and what it means in the real world.
Day 8 - Ummm... I'm drawing a blank. It's a 10 day lecture series, damnit!
Day 9 - Launch rockets and measure altitudes via commercial altimeters as well as old school triangulation.
Day 10 - Backup launch day (weather!) or discussion of why predictions didn't match measured altitudes (and measured altitudes didn't match each other).
Well, what we "hand out" is kits for Estes Alpha rockets.
