No new space-related work (defected/returned to the aviators for a while) but did do another stomp rocket session with the little-people. Ten this time, but had a summer intern along with the "real" teacher so between us we kept the horde moving forward.
Built the same simple rockets as last time (see above). Cut out the parts, color (popular activity), assemble with a little scotch tape, and head out to the launching pad.
I used two dual lauchers (see page two on the launcher pdf above) so we launched four rockets at a time. That made sure everyone got to launch several times, and rotated them throught the launch queue quickly. One loader on each tube, range safety/launch controller to do the countdown, and a stomper. Rotate the jobs as they move up in line.
After three or four launches for each we did "what if." Launched two identically built rockets of differing weights (little and big clay blobs under a nose cone). Which one will go further ... let's do the experiment and find out. Also did a low angle versus 45-degree angle launch - which one will go further? Finally, launched a short, stubby rocket and a long skinny one - which one will go further (answer: don't know. They both ended up in a big live oak about 150 feet down range - ah well, it's just paper). Ended the session as the day heated up so we didn't try for a moon landing (try and land your rocket in a 5-gallon bucket 40-50 feet downrange).
And then home, for a nap ....
