Rocks and Minerals Class Kit
book not included, please order separately
WE SUPPLY all items in our above Starter Kit, in class quantities that serve up to 30 students organized into 10 lab groups. YOU SUPPLY other materials as detailed above.
Baby Food Jars - assorted
Each set includes 4 small, 4 medium and 4 large glass jars.
Candles - emergency
cylindrical, 5 inches by about 3/4 inches diameter
Also called utility candles. A handy heating source. Correctly sized for #09 Floating and Sinking. Drip catchers not included.
16-mm film-canister, snap-on lid
Once ubiquitous, now hard to find. Needed for #09 Floating and Sinking, #16 Pressure, and #23 Rocks and Minerals.
Clay - modeling
Sold by the 100 gram stick, about 1/4 cup, in assorted colors (our choice). One stick serves a whole classroom for TOPS applications.
glass, with rubber bulbs and screw-on plastic bottle top
These have many lab uses. You may purchase them separately here, or with 1/2 ounce dropper bottles (as item #1121).
Separately, these also double as Cartesian Divers in #200 Diving into Pressure & Buoyancy. If you already have droppers, test them in advance to see if they make good 'divers': Remove plastic bottle top, if any. Dropper must float when empty, then sink with a one-squeeze-intake of water. Test that the seal between bulb and barrel is water tight: The empty dropper should float for a day or so in a glass of water, without taking on visible water.
Graduated Cylinder - 100 mL
shatter resistant plastic on stable base
An important lab inquiry tool for measuring larger liquid volumes.
Gram Pocket Scale
digital, pocket size
Digitally weighs up to 500 grams, plus tare container. Sensitive to 0.1 gram in multiple weight units. Durable, but not childproof. Comes with two AAA batteries to get you started.
Magnifier - hand lens
3X clear plastic hand lens
You'll find many uses for this basic tool of scientific inquiry. Very nice quality for the price. Supports #17 Light, #23 Rocks and Minerals, and #42 Focus Pocus. (One 3X hand lens is also included in each #100 Triple Magnifier Kit.)
glass, standard size
Used in #17 Light for diffraction experiments. For viewing microscope specimens, consider cutting slides, almost for free, from clear plastic bakery cartons. Smooth any sharp edges with sandpaper or an emery board.
size #1, steel, box of 100
Paper clips have 1001 uses in TOPS experiments, and science in general. Feel free to use paper clips you already have, but be aware that different brands come in different sizes and weights. In experiments where uniformity is important, don't mix brands.
