Wonderful little book jammed with elaborate colored drawings that tells the beginner a little about everything to do with a microscope. And all in a mere 48 pages! From data on the history and types of microscopes, to introductions and samples and how to prepare them, (from tissues and insects to crystals) to ideas for experiments and lists of simple equipment needs, and how to build them at home, this book is a veritable cornucopia of information. If you are thinking of getting a microscope, we strongly recommend "The World of the Microscope" as a great stimulus for the novice user. It won't answer heavy duty scientific questions. But it will keep the beginner busy, challenged and entertained for days and weeks! By Chris Oxlade and Corrine Stockley. Paperback, 7-3/4" x 9-3/4". One of the Usborne science and experiments series of books.

White chalk is fine but imagine the possibilities of a full palette of colors. Looks nice, right? Our box is (16) pieces of washable chalk at 3-1/8” long x 3/8” dia, and you’ll get (3) boxes, each with (2) pieces of green, purple, yellow, pink, hotter pink, blue, orange and white, which is a color too.

These mighty nice little ceramic disc magnets measure 18mm dia x 6.5mm thick, which in America, Burma and Liberia is 23/32" x 1/4", and for those of us still math-impaired, roughly a stack of (5) dimes. They have a 1/4-lb pull. No crafter should be without an enormous supply of these. Also note the physics-class-friendly bulk price.

Beautiful refrigerator magnets, all set to be imbedded in your child's best ever creation for refrigerator work. Six file card holding power, 3/4" dia x 3/16" thick ceramic with beveled edges to minimize chipping. They don't come much better than that!!

Nothing says fun science like stuff blowing up or falling down. Ask any middle-schooler. Get them started with one of these excellent books: Massively Epic Engineering Disasters, a 241-page hard-cover book devoted to (20) mishaps through the ages, plus (33) experiments based on the principles that caused them; or Potentially Catastrophic Science, 306 pages with (50) experiments ranging from pre-history to the present. Taken together, they cover everything from collapsing cathedrals and sunken boats to sonic booms and batteries.

Bring back cursive writing with this 40-sheet, bound writing tablet for kiddies, with 1/2” blue rules divided by a dotted line to help place ascenders and descenders. Pages are 10” wide x 8” long, and the inside cover has both cursive and print alphabets in upper and lower case. For grades 2 and 3.

Who among us doesn’t? Even a just man falls seven times. Just get this little eraser wheel, 1-7/8" dia x 3/8" thick in latex-fee rubber. The plastic housing rotates to keep it closed and schmutz-free in your drawer, just waiting for you to err.

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.

It’s a scientific breakthrough! Oh, wait, no, it’s a rare-earth magnet encased in white plastic. Great for holding notes on your white refrigerator without clashing. Measures 1-1/4” x 3/8” x 5/16” and also has a piece of self-adhesive foam on the back to stick where magnets won’t grab.

Why do your feet look like they are attached at a different angle when you're standing in water at the beach? Teach the children with this plastic water prism. Also make rainbows. Measures 8-1/4" x 2" x 1" with 3/8" squares across the surface to measure refraction.

Geometry teacher alert. These 6" plastic protractors have a 6" x 1/16" ruler on the bottom, and measure 0-180 degrees in one-degree increments on the outer arc and 10-170 degrees and 10cm ruler on the inner side. You’ll get a quartet of them in assorted colors, including clear and translucent red and blue.

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.

The kind you hang in the front of the laboratory or on the classroom wall, which is what we suggest you do with this one. Measures 38" x 50" and is laminated to protect it from flying students. Has an aluminum frame and hang tabs on the back side. Brand new! Great quality. Please note: This item is not available for expedited shipping.

Please Note: Your entire order will ship standard ground when purchasing this item and the actual shipping costs will be charged. Thanks!

We like The Usborne Book of Science Activities a whole bunch. It’s volume one of the Helen Edom and Kate Woodward series, a 74-page hardcover that includes experiments with water, magnets, light and mirrors, with plenty of puzzles and projects--profusely illustrated, throughout. Handy for keeping your young one's mind in shape when not in school or as family learning projects.

Clever little plastic boxes 4-1/2" x 2-1/4" x 1" hold note paper - and dispense one sheet at a time as you open and close the cover. The clear red box is labeled "Mom". They work even better with business cards, so they make great little gifts if Mom has her own cards. We'll send you a bag of (3) with each order. 

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.

An embarrassed jellyfish. Also this 50-sheet pad of 3" square sticky notes, guaranteed to stand out among all the little pale boring ones. You'll get (3) pads in your package in assorted bright neon colors; we've seen pink, yellow and orange so far. Say that three times fast.

A tad smaller in diameter than a ping pong ball, this colorful steel geographic globe is 1-3/8" dia, but pull out the little base it stands on and you’ll find a small pencil sharpener hidden inside. Also suitable for hiding secret messages, which is always handy.
