TAPT-ers,
Sorry, I neglected to send this over the weekend, I
temporarily lost it in my mountains of email.
From Jim:
Here
is a list of items that I have in some degree of surplus, and available to
bring
Float
and chain engineering problem solving set: ability to make one each of a
thermometer, a hydrometer, a barometer, and a milligram balance, and to modify
them to vary their sensitivity and/or range. This was discontinued from
PASCO's catalog a few years ago in a housekeeping purge, but perhaps someone
has an old pasco catalog and could see details. This was my response to
need for STEM before STEM became a thing.
Mirrors
150 mm sq, with a base that holds them normal to a table top. Lots of uses
besides the obvious.
Density
sets of 12 pieces of aluminum, all different sizes. Graphing mass vs
volume gives a straight line graph, whose slope is the density of aluminum.
UV
color shifting beads, white but become colored under uv, including the uv in
sunlight. Then return to white after a delay. also transparent disks that
appear identical, but some block uv, while some transmit it. results can
be seen using the beads.
thick
plastic material that has amazing thermal expansion in hot or cold tap
water. disks, and pieces that have holes that are a near fit for the
disks. like the classic brass ball and ring apparatus, but no bunsen
burner is needed.
Small
vacuum pump and bell jar, a few sets.
Singing
rods, that can can be stroked to make a longitudinal oscillation with loud
sound.
A
small number (3?) to donate of the dial indicatiors that I showed once before
that Karie mentioned in her e-mail. They show how it is that a seemingly
immovable floor or wall can exert a force. I will try to bring some
ancillary parts to make all this ready to do this demo.
No
guarantees as to quantities I can bring, but I will bring the largest item of
luggage allowable on the plane, and will try to respond to requests. NOTE
NOTE NOTE I will seal up the box or large suitcase Tuesday night
(1/23)
so any requests after will likely have to wait an extra year.
