March 6, 2004, Non-Computer Based Data Acquisition; "White Elephant" Sharing & Quarknet
Hosts: David Lay and Gene Allard
Place: Parkway North High: 12860 Fee Fee Rd. (West on 364 from 270 and get off on the Benington exit. -- If you go too far, turn around on the Maryland Hts. Expressway ñ and then go South on Benington to Fee Fee Rd, and turn right. P. North will be just around the bend!).
Bring one or two items to trade and share
Time 7:30-11am

This should be a fun time: Debbie Gremmelsbacher will start it off with a presentation on Quark Net followed by yours truly focusing on using the storage oscilloscope in mechanics, e&m, and optics measurements I'll also be demonstrating a digital timer that calculates velocity and acceleration. Oh, and if you think that is exciting, weíll do all of our calculations on slide rules! But wait! If you act now, you'll get a free (well, almost) homemade slide rule!!!! Actually, any of you with interest and who wish to stick around, we can build slide rules in the afternoon. THEN Gene Allard will be running the white elephant. There will be a continental breakfast and socializing at 7:30 am, so be there!

Any questions, you may call me at 314-415-5630.

David's setup for measuring free-fall acceleration. The power supply energizes the photogate which is connected to the storage oscilloscope. When the picket fence is dropped through the photogate, the alternating bands seen on the oscilloscope screen are recorded. Students can use the horizontal time scale to record how long each of the bars blocks the photogate.
