>Hello fellow Science Enthusiasts: A quick note to remind you that this 
month's YAPA meeting will be at Canfield High.  Our host is Steve 
Hlaudy.  A map is attached.   As usual, the meeting will start about 
7:00 P.M. and last until we've all had a chance to share (usually 
between 8:30 and 9:00).   We'll aim this time for momentum and energy, 
but will be interested in anything you care to share. Hope to see you 
there. Roy and Mike For those who couldn't make September's meeting:
>What you missed:
>Dick Zitto started by sharing some give away items he found as he was 
cleaning out his barn.   This included a $280+ CPO demonstration 
electric motor that will be given away at November’s YAPA meeting.  You 
can look it up on CPO’s website.  … Be there.

to help your students’ perspective on geeks.

>This was followed by Mike Crismano with several sharing/give away 
items… Clearing out the storage area, he found torque pipes to give 
away.  He followed this with demonstrating the effect of free fall on a 
burning candle.  He next showed us a new way to “rip” a CD.   Using 
tape to peel of the paint layer of CD’s often produces a very useful 
transmission diffraction grating…when combined with a shoe box, this 
produced a quality, inexpensive spectroscope.   We hope to do this as a 
make and take at the November YAPA meeting, so plan to come and bring a 
shoe box along.  Mike finished his show with a simple conductivity 
tester that allowed one to test the conductivity of a solution using 
battery level voltage… this lead to a lively discussion of Jarod’s law.

>Jim Andrews followed with a teaser from his workshop at this weekend’s 
Ohio Section of AAPT meeting.  If you haven’t gotten work of it.  The 
meeting is at Lorain County Community College (North of Elyria) and 
starts Saturday at 9:00 A.M.  They never turn away people who register 
at the door.  Jim’s workshop is on Intro to Materials Physics-Polymers 
and will have several work stations where participants can investigate 
the how polymers differ based on their physical and chemical exposure 
(You’ll definitely want to check out happy and sad balls that are at 
temperature extremes.)  His teaser involved investigating the density 
of different polymers.

>Roy McCullough followed with a group demonstration on scale models of 
the solar system.  Starting with a scale that made planetary sizes 
viewable and the Sun about 30 cm in size, we found that we ran out of 
hallway space.   Scaling back to a standard light bulb for the Sun we 
still couldn’t get beyond Jupiter…Finally, with a maglite size Sun, we 
got out to the dwarf planet Pluto.
