Complete Master List for #95 Try This On for Science:
These are the ONLY materials you may NOT already have or may find challenging to locate. All are available for purchase below!
- An ounce scale or gram scale (for books 05, 09).
- A 10 mL graduated cylinder (for book 09).
- Dropper bottles with screw-on eyedroppers (for books 10, 13).
- Steel wool (for books 11, 15).
- A test tube (for book 12).
- Bell wire (for book 19).
- Ceramic 'refrigerator' magnets (for books 19, 20, 33).
- Very thin bare copper wire (for book 20).
- Epsom salts (for book 23); purchase in the home remedy section of your local pharmacy.
- Sugar cubes (for book 35).
- A canning ring (for book 101)
Canning Rings with Lids
fit regular-mouth canning jars
These may be available only seasonally in some stores. Avoid wide-mouth size. Needed for #16 Pressure and #17 Light. Only rings (not lids) are used in #40 Earth, Moon & Sun, and #43 Focus Pocus.
Dropper Bottle with Eyedropper
1/2 ounce, amber glass
Very handy for storing and conveniently dispensing small quantities of liquid. You may also purchase eyedroppers without bottles as item #1120.
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 - 10 mL
shatter resistant plastic on stable base
An important lab inquiry tool for measuring small 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.
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.
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.
126 cubes (not bricks), teaspoon-size
This is a specialty item for #35 Metric Measuring.
Test Tube - medium disposable
19 mL capacity, 16 mm OD, 5 inch (125 mm) length
A lighter weight rimless Pyrex test tube made with thinner glass.
Test Tube - medium reusable
14 mL capacity, 15 mm OD, 5 inch (125 mm) length
A tough Pyrex test tube made with rim and thicker glass. Has a white spot for labeling.
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.
