AAPT ANNUAL FALL MEETING
Date: Sat, 6 Sep 2008
Recorded by Liz King
Thanks to Mike Weber for refreshments!
Agenda:
Roundtable Introductions
New Teacher Welcome /New Teacher Workshops (Jeanine Nakakura)
History: Mike Jones wrote a grant to pair new and veteran
teachers to construct a physics demo device to share at a following
meeting. The idea was to support new teachers or teachers who teach
out of field.
Current project: Jeanine wrote another grant when the old one ran
out; in this one, new teachers or out-of-field teachers are paired
with veteran teachers and given a demo book. Eight pairs of teachers
received a demo book, and the pairs can request funds for supplies.
Sometime in January, we will have a meeting to share what they came up
with. ALL are invited to come see the results!
Derek Minakami hosted a New Teacher Workshop to give new teachers
resources and ideas that they can use right away to help them launch
into the new teaching year. It met with great success, with calls for
another workshop later this year dealing with a different topic.

Sharing of ideas and teaching demos:
Jim Redmond: lots of freebies from AAPT to share. Demo: in a
dark room, shine a transparent ball that has RGB L.E.Ds swing around
and the colors will separate you will see RGB and what ought to be
white (supplies available at Education Innovations). A little red LED
push light from Innova (available at City Mill and Target) can
bright or less bright. If you swing it on dim, you can see that the
light blinks thats how they make it dim. If you swing it on high
power, the light is steady. If you can figure out the blinking rate
and attach it to something that falls, you can figure out some
interesting things. Also showed a light that glows different colors
in sequence good for additive light. Demod the new LabQuest from
Vernier that is replacing the old LabPro interface. And, Presidian
Radar Pitch Baseball - a baseball with screen in it that shows how
fast its going you set the distance (20-80 feet), and it has a
timer inside that does the math. Available for $4 at Radio Shack.
Brian Pyper . Conservation of momentum: Basket ball and tennis
ball drop separately, then drop them with the little one on top and
the big one wont bounce and the little one will flyPen, ballpoint
cheap non-clicky. Take the guts out so that you just have an empty
tube. Put it on a table and with your thumbs, squeeze it with some
back spin. It will get lift and fly around and be very cool. With a
piece of paper, blow over the top of it and it comes up due to lift,
again. Center of mass demo: stand 2 foot lengths away from a wall,
lean over and put your head on the wall and stand up. Repeat but pick
up a stool first; Girls can, boys cant.
Mike Weber long long long plastic bag, try to blow it up with
least # of breaths. The trick is to use Bernoullis Principal to fill
with one breath by holding it away from your mouth when you fill it.
Hanno A University of Washington McDermitt and Schaeffer (?)
tutorial about velocity. Uses a spark timer to study motion, provides
questions for discussion and dialogue. The Website is from a physics
education re
Aaron demod some leyden jars he made. Instructions are
plentiful on the Net.
Roger Kwok demod the physics behind some common toys. Ball
and cup on string swing the ball and catch it in the cup. The trick
is to use inertia ball is heavy and if it swings straight up, it
will slow and hang momentarily, at which time you slip the cup under
it. Ns 3rd law if you try to swing the ball onto the cup, the
collision causes the ball to bounce off. If you spin the ball before
you lift it up, its a lot more stable and is easier to poke the spike
on the handle thru the hole in the ball. Center of Gravity balancing
birds (also look to nature see how a pigeon walks so that the cog in
its belly is always over its feet) and little adjustable man-toy
bring arms up and you can balance him on his chin. Bottle holders that
use same idea. Earnest the Bear rides a bicycle across a tightrope b/c
his cog is below the rope. Use a wooden ruler, tie a hammer to it,
balance it on a table
Center of gravity shown by bold arrow
A little walking penguin pulled by a weight on a string hanging off
the edge of a table walks toward the and stops right at the edge. 2
person demo one braces w/feet apart and cannot be easily moved if
pushed in one direction but can be easily moved if pushed at 90 to
original direction. He used little blocks of 2x4 to show the physics:
sorry, too hard to show/explain here in these notes.
