Scott Thomas: Hey John
Me: Hey Scott
Me: This should be interesting.
Scott Thomas: Tried to spread the word about GPD at FIU modeling wksp today. I’m interested to see how many come
Me: cool!
Me: There was a lot of activity on the corkboard site
Me: I think andy’s wife should be on soon to promote us to admins…
Scott Thomas: I’m guessing she
Scott Thomas: ‘s very excited
Scott Thomas: I know my wife would be thrilled to fill in for me for a group of physics teachers
Me: yes. mine too, and she’s a physics major
Me: hmm, if she doesn’t join, then we will probaby be limited to voice/text chat
Scott Thomas: mine’s an MS english teacher
Scott Thomas: Hi Jason
Me: we now have enout people for 1 word stories…
pbr56: hello
Me: enough
Me: Jason, would you like to start?
Me: The idea is that each person writes 1 word of a physics related story.
pbr56: forces
Scott Thomas: Adding punctuation when needed
Me: great pam started us with forces. So it will be scott, jason, me
Scott Thomas: are
pbr56: I had the easy part, that is why I started.
Me: Jason?
pbr56: Forces are Jason?????
pbr56: LOL
Scott Thomas: he must be multitasking
Me: no. my word will be balanced.
Me: Forces are balanced…
pbr56: Unless
Scott Thomas: there
pbr56: are
Scott Thomas: other
Me: external
pbr56: Forces
Scott Thomas: which
pbr56: one sec, have to finish mushing strawberries for the jam.
Me: cause
pbr56: them
Scott Thomas: to
Me: be
pbr56: unbalanced.
Scott Thomas: Models
Me: are
Me: http://corkboard.me/6qbAPElHW1
Me: anyone there?
Scott Thomas: yes
pbr56: yes
pbr56: okay
Scott Thomas: not sure if it will work or not
Scott Thomas: yes
Scott Thomas: I use the CPO program right now, able to get to waves
pbr56: that is the one that has a lot of stuff on a cd
Me: http://www.cposcience.com/home/Home/tabid/119/Default.aspx
Matt Keye (@mattkeye): video analysis is a great idea
Scott Thomas: no, it’s a curriculum
Me: http://www.cposcience.com/home/ForEducators/FoundationsofPhysics/tabid/272/De…
pbr56: I use it for freshman science and it is too difficult for my freshman with the worksheets. I didn’t get the lab equipmen.t
Me: http://www.cposcience.com/home/ForEducators/FoundationsofPhysics/tabid/272/De…
pbr56: I use spaghetti.
pbr56: just to get my freshman started on E and M
pbr56: I Like it, but I should add slinkys
pbr56: I use a jigsaw and an elastic sting

Matt Keye (@mattkeye): interference: http://audacity.sourceforge.net/ you can make your own sound files and combine two waveforms together and show either constructive or destructive interference by inverting one of the waveforms or by keeping the waveforms unaltered

Scott Thomas: I think filters comments to make them “student friendly:
Moderator (john (occam98)): http://quietube.com/
Moderator (john (occam98)): clean up comments
Scott Thomas: just as a second side conversation, do people know about the pgp site?
pbr56: all signed up to diigo.
pbr56: now need to play with it.

Moderator (john (occam98)): click on join link on Wikispaces page:
Moderator (john (occam98)): https://secure-pgp.wikispaces.com/
Moderator (john (occam98)): must pass along link to your school website that shows you are a faculty member.
pbr56: It is good you told me how. It doesn’t say that in the request
pbr56: I just requested member ship.
pbr56: I am still trying to learn vpython. So much to look over this summer.
Bryan Battaglia (brybatt): I did too. But didn’t know about the rules. Hopefuly they will ask me to prove it!
Bryan Battaglia (brybatt): I like the tuning fork overhead.
Scott Thomas: I do that with a tuning fork
pbr56: explain. I think
Bryan Battaglia (brybatt): Yep. Ties to a string.
Matt Keye (@mattkeye): simple idea: put a tone generator in a nerf football and have students line up on field and have someone throw it as far as they can
pbr56: It makes noise?
Bryan Battaglia (brybatt): me too.
pbr56: I didn’t know that.
Bryan Battaglia (brybatt): like the football idea.
pbr56: That was a dumb question.
pbr56: I was thinking it would make noise if you swung it.
Bryan Battaglia (brybatt): I have my students stand in the middle of the parking lot and then I race at them honking my horn.
Moderator (john (occam98)): http://www.pasco.com/physuniv/waves-and-sound/doppler-effect.cfm
pbr56: LOL
pbr56: Bryan
DaveWiggins: They can’t get out of the way until they calculate your speed from the shift.
Jason Stine: arbor has an inexpensive doppler ball http://www.arborsci.com/prod-Doppler_Ball-485.aspx
Bryan Battaglia (brybatt): Hurry! Hand me the calculator!
Scott Thomas: not really
Bryan Battaglia (brybatt): no. I have a probes based lab in a book at school that has one but I’ve never tried it.
Moderator (john (occam98)): complete MIT OCW course (w/ lecture) on vibrations & waves; http://ocw.mit.edu/courses/physics/8-03-physics-iii-vibrations-and-waves-fall…
Matt Keye (@mattkeye): speed of sound: two planks of wood, large reflective wall 80 meters away, timers, listen for echo…the quick and easy way
Matt Keye (@mattkeye): yeah, hard to get great results
Bryan Battaglia (brybatt): exactly 80 meters?
pbr56: http://www.lon-capa.org/~mmp/applist/doppler/d.htm
Matt Keye (@mattkeye): no, but it needs to be far enough for reaction time reasons
Bryan Battaglia (brybatt): I like that one.
pbr56: yes
Moderator (john (occam98)): http://streaming.discoveryeducation.com/
Bryan Battaglia (brybatt): For free now? They have been raping for episodes up til now.
pbr56: I have post my videos
Bryan Battaglia (brybatt): I think it is a pay thing.
pbr56: kids can watch the videos at home.
Bryan Battaglia (brybatt): My district has a site license.

Brainstorming for waves (6/29/2011)
Hi everyone,
Let’s try to use the following to help brainstorm what to talk about regarding teaching waves:
http://corkboard.me/6qbAPElHW1
It’s a virtual corkboard that lets you place down “sticky notes” with ideas about what you’d like to share/learn about/complain about regarding teaching waves.
Anyone can create/delete/move the stickys with the link above. What would be cool is if we could organically group similar items and let the size of the various groups help us figure out how to organize our time together next week.
Thanks!
-Andy
LaTeX (6/22/2011)
Tonight we talked about how to use LaTeX to help with equation typesetting and full document creation. We discussed LaTeXiT, gdocs, gmail, online editors, LyX, and TeXnicCenter.
After that we had a great brainstorming session about other things to do with GPD
- More big name speakers. We’ll send the invites out soon. Email me (andy.rundquist@gmail.com) with any ideas for this
- Research (how various levels of students understand, say, a ball being thrown. Maybe getting video of students explaining things).
- Physics teaching help (see below)
For next week we’re excited to try an experiment. We’ve (arbitrarily) picked a physics topic for people to come and share how they teach it, questions they have, resources they’ve found useful etc. For next week we’ve decided on waves as the topic.
Tom Moore 6/15/11
Tonight we spoke with Tom Moore, author of the “Six Ideas that Shaped Physics” textbook. We talked about active engagement, publishing, and computer programs/programming.
Rhett Allain (6/8/11)
Tonight we talked with blogger extraordinaire, Rhett Allain, who blogs for Wired.com. We talked about social media, sports science, Mythbusters and more. Here’s the recording.
Ruth Chabay and Bruce Sherwood on “Matter and Interactions” June 1, 2011
Tonight we heard from Ruth and Bruce about the philosophy behind their calculus-based introductory physics text. We talked about 20th century physics, fundamental principles, computation in physics courses, and even a little about women in physics.
