#### Materials to Purchase

#### Available and Recycled Materials

#### School Supplies

## Convenient Shopping:

### Aluminum Foil

*regular strength, 20 square feet x 12 inches rolls*

Buy aluminum foil here as a convenience item, or for less in many grocery stores.

### Baby Food Jars - assorted

*without lids*

Each set includes 4 small, 4 medium and 4 large glass jars.

### Batteries

*size-D, alkaline*

These are basic workhorse brands, available everywhere.

### Bottle Caps

*crimped-edge, new*

Ideal for counting, uniform weights, and mini-containers to hold small portions of chemicals. These unused caps flare more widely than recycled caps. Used bottle caps, if unbent/undamaged, are an excellent free alternative.

### Clothespins

*wooden, spring-action*

These are handy lab items to keep in stock. We use them as bulb holders, tongs, clips, and more.

### Flashlight Bulbs

*4.5 volt, with collar*

This traditional filament bulb shines reliably bright (won't blow out) with 3 size-D batteries, yet still glows visibly with just 1 battery. Used in #19 Electricity, #32 Electricity, and #91 Global TOPS.

Tips on shopping elsewhere: Select bulbs with protruding metal 'collars' to facilitate secure integration into clothespin bulb-holders. Use just one bulb brand and resistance rating so all bulbs shine with equal brightness when powered by equal voltage.

### 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.

### Paper Clips

*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 Wool

*fine grade, unsoaped*

A handy lab supply, for studying electricity. Each pad is about the size of a classic Shredded Wheat biscuit. Used in #11 Oxidation and #32 Electricity.

### Straight Pins

*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.

### Thread

*light duty, 25 yd spool*

Just plain old thread. Used in many TOPS titles, especially in Pendulums #34.

### 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.

### Teaching Tips for #91 Global TOPS Resource Manual:

We encourage improvisation - it's one of the main goals of our hands-on approach! You and your students might invent a simpler, sturdier or more accurate system; might ask a better question; might design a better extension. Hooray for ingenuity! When this occurs, we'd love to hear about it and share it with other educators. Please send ideas and photos to tops@canby.com.
