TEACHING / DEMO / LAB EQUIPMENT

They might as well learn something while they're trying to outlast you on eating those lima beans. Set the table with educational placemats and they'll be at least a touch smarter after dinner, even if their vegetable intake is low. These laminated, 12" x 17-3/8" mats have full-color fronts, black-and-white backs. Choose the United States Map, Stars & Constellations, the Periodic Table of Elements or The Metric System.

Nice little teaching magnet set for the primary grade classroom has (6) magnets in star, two-bar, horseshoe and ring shapes, all plastic coated in silver and red to mark the poles. Range in size from 1” to 3”, and include a few paper clips and small nails for demo purposes.

Classroom and Science Fair alert: Now you can order an 8-pack of metals and metal alloys for demonstration purposes. Each pack of 1" dia x 1/32" thick discs includes aluminum, bronze, brass, copper, n/silver (w/nickel), m/steel (mild: low carbon), stainless steel, and zinc. Composition of each is stamped on one side of the discs.

Our compact 4” dia globes have smooth dual axes rotation and measure 5" wide x 6" high overall, including the nice black stand they’re attached to. All show their features in excellent detail. You pick: the Moon globe, showing craters, seas, rilles, valleys, mountain ranges and landing sites of manned and unmanned missions; the Celestial globe with stars, constellations and celestial images by noted German cartographer Karl Harig; the Political globe with an easy-to-read map indicating political borders and capital cities; the Antique-Style Political globe, which is like the Political globe, but old-time looking; or the Satellite globe, which shows the landmasses and oceans of earth as they appear from satellites. A few different globes next to each other make for a really great display, but they’re all nice enough to stand alone.

An easy way to light up the kids' eyes! Teach them to wire a simple circuit with our basic components.

The knife switches are mounted on a plastic bases.

The miniature plastic socket holds a standard flashlight bulb with a 14 mm dia screw base.

We pack 6 volt and 3 volt round bulbs, or 1.5 volt bell-shaped bulbs, (5) to a package.(Bulbs are rated slightly higher to prevent them from burning out.)

Hook up the black plastic and metal 2" x 4-1/4" telegraph key with brass contacts and (2) terminal posts with nuts.

Our blue-plastic holder for (1) "D" battery has a small tab at each end to hook a lead to, and a 1/8" square mounting hole at each corner.

You add the mounting surface and the know-how. Actual bulb voltage listed in parenthesis.

Same here. Try the Ferrofluid Magnetic Display, a little sealed bottle with virtually fluid nano-particles of ferrous metal suspended in liquid. You’ll get (4) powerful 1/2” dia x 3/16” neodymium disc magnets, (2) of them attached to chess-pawnish holders. Move the magnets in assorted combinations around the bottle for fascinating effects. Sort of the marriage of science with desk toys, but students can’t spill these particles all over the place.

You can start with our single aluminum tuning fork, 2-tined and 7-1/2" long. It vibrates at 256 hz, and is labeled "C". Or you can order the set that has (8) forks and a mallet with a rubber-tipped plastic head. The forks are labeled low-C to high-C and come in a fitted, latched wooden box. Unfortunately, C.J., who has perfect pitch, tells us that his pitch is more perfect than most of the tuning forks. He also says you can file the tips, tuning them to an electronic keyboard until they're perfect - and we think there's a certain cachet to telling people you tuned the forks yourself. But they are perfect, if you're using them for things like teaching principles of sound or driving the chihuahua crazy.

The next best thing to lightning bolts! 200,000 volts of electrostatic energy created by our Van de Graaff generator. Measures 6-1/2” diameter by 15” tall, includes a spare belt and a set of instructions detailing lots of fun experiments. For grade 6 and up. This is not a toy and should be used under adult supervision. A great tool for teaching about electricity. For your convenience, we now have Lightning Belts: replacement belts to drive that overworked generator. Operates on Standard 120 VAC with the included 3' cord.

The human body is a puzzle, really. Get a head-start on anatomy class with one of these anatomically correct breakaway models in authentically colored plastic with detailed cross-sections. Pick the 2" tall, 7-piece eyeball; the 3-1/2" tall, 6-piece human heart; or the 3-3/8" tall, 6-piece rubber and plastic human head/skull/brain. All stand on 3" square bases.

…when you crank up this 13-1/4" tall, hand-cranked Wimshurst generator. They were the toast of the 19th Century, and remained the hottest thing around, electrostatically speaking, until Bobby Van de Graaf came along. This one works like a top, zapping sparks to a fare-thee-well with very little cranking. It's mighty pretty too, in acrylic, white and silver, and will dress up a dull physics or electronics lab.

That's what you get with this tesla coil!! Brand new, commercial item, great for classroom demonstrations and experiments. The 50,000 volt capacity generator radiates high frequency energy through space... enough to light fluorescent tubes two feet away. It uses 115 VAC (60 Hz) with an electro-magnetically operated interrupter buzzer, high voltage capacitors, inductive coil transformer, and a monopolar high frequency transformer generator to do the trick. 11" high, with a 6" sq. x 2" high protective housing for the generator. Includes accessories and instruction booklet with 19 experiments. Pretty amazing. But please, this is not a toy and should be used only under adult supervision.

Y columna vertebral. Y the bones, fractures and dislocations associated with them. All the text on these 26” x 20” slightly glossy anatomical charts featuring the shoulder, elbow and spinal column is in Spanish. If you want them for a classroom or a doctor’s office, better get them fast, before they sell out as funky wall art.

You choose between our 2" square classroom demonstration slides. The diffraction grating slide has 500 lines per mm resolution and a wavelength chart; the linear polarized filter slide has a 1-3/8” x 15/16” window. Nice for classroom and home-schooling use. Made in the USA.

Like those giant floor-standing globes in places like explorers’ clubs, but just under a foot tall. From Replogle Globes, this very nice 6” version honors explorer Sebastian Cabot and is based on the late 17th Century globes of cartographer Vincenzo Coronelli, when California was still thought to be an island. Stands 11-1/2” tall with a 4-1/4” wooden base and a 7” semi-meridian.

Just like your own, but in rubber instead of bone. Our super realistic, anatomically correct skeletal hand and foot models are great for a medical office, anatomy lab, art studio, Halloween party, or just to add a little orthopizzazz to your living room all year long. You choose the right hand and wrist, 8” long on a 4-1/4” square base with a detailed diagram of dorsal and plantar views; or the equally detailed right foot and ankle, also 8” long on a square base with the same views diagrammed.
