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

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): I don’t have a mic tonight, still need to get one…

 

 

Scott Thomas: One of the cool things I found was to set up the frequence at about 60Hz, and put it infront of a computer moniter/tv

 

 

Matt Keye (@mattkeye): great, thanks for the link

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

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.

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!

Bryan Battaglia (brybatt): no. I have a probes based lab in a book at school that has one but I’ve never tried it.

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.

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.

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. 

Here’s the recording for tonight.
