Magnetism Class Kit
book and magnets NOT included, please order separately
WE SUPPLY all items in our above Starter Kit in quantities that serve up to 30 students working in 15 lab pairs: YOU SUPPLY other materials as detailed above.
regular strength, 20 square feet x 12 inches rolls
Buy aluminum foil here as a convenience item, or for less in many grocery stores.
These are basic workhorse brands, available everywhere.
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.
These are handy lab items to keep in stock. We use them as bulb holders, tongs, clips, and more.
Cups - plastic
9 or 10 ounce; clear, flexible, plastic
"Solo" brand or equivalent sold in grocery stores is suitable. Avoid brittle plastic. Used in #16 Pressure.
Magnet - ceramic
rectangle, 3/16 inch thick
Your basic refrigerator magnet, about the width and length of a large postage stamp, with N and S poles on each face and a hole in the middle. A useful and popular science supply used in may TOPS titles. Purchase at least 2 per student.
Nails - 2 1/2 inch
steel carpenter's flat-head nail, 10-penny
Used in some TOPS titles. A surprisingly handy scientific supply.
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.
Rubber Bands - assorted
10 grams each of thin, medium and thick
You get 30 grams of soft, strong, durable rubber bands: thin #16 (about 50), medium #32 (about 20), and heavy-duty #64 (about 10). These sizes are specifically selected to work in most TOPS experiments.
steel, one and 1/16 inch long
Used in many TOPS experiments. Sometimes required for their magnetic properties. Don't purchase aluminum straight pins by mistake.
Tape - clear
3/4 inch x 1000 inch roll
Your standard desk tape with matte write-on surface.
Tape - masking
3/4 inch x 55 yd roll
A handy science supply used in most TOPS modules.
light duty, 25 yd spool
Just plain old thread. Used in many TOPS titles, especially in Pendulums #34.
Washers - small
7/8 inch flat washer with 3/8 inch hole
Used in many TOPS labs. Item #1290 (medium tubing) used in #16 Pressure fits through these smaller washers.
Wire - wrapping
100 feet, plastic insulated
Also called magnet wire or bell wire. This science-lab staple is used in #19 Electricity, #20 Magnetism, #33 Magnetism, and #91 Global TOPS.
Wrapping wire may be recycled from old motors or transformers. If insulated with paint rather than plastic tubing, end leads will need to be sandpapered clean, not stripped with pliers.
Wire - very thin copper
The thinner the better. Old household appliance cords may be braided into suitably thin strands. Nip the insulation with wire stripping pliers, then pull off the insulation to inspect. This is a speciality item for #20 Magnetism and #33 Magnetism.
