Scientifically speaking. This 8-1/2" x 11" science reference notebook is three-hole punched for inclusion in a binder. From McGraw-Hill, it's heavily illustrated and filled with facts, illustrations and definitions about biology, geology, astronomy, physics and much more. Science! Surplus factor: some may have been packed before the cover ink was dry, leaving a slight speckled pattern that has no effect on the science inside—we checked. And Science is our middle name.

If you’d like to, too, we have three ways for you: our Go Wild Special is a canister with 1 oz of wildflower seeds in approx (25) varieties chosen to appeal to pollinators and to fill about 150 square feet in USDA zones 3-11, which is pretty much North America; our Here Comes the Sun option has 2.5 oz of sunflower seeds so you can become the food source for birds and baseball players all summer; and our Johnny Sequoiaseed option has (7) sequoia tree seeds per packet, along with 1/2 oz of soil, a small bag of pebbles and a vented canister to get them started so that in approx (83) generations, your progeny will have a tree 36 feet in diameter. Better pick a wide spot in the yard for that one.

Keep your magnetic hematite. Keep it tight! And keep it close because word on the street is, it has potential healing powers, or at least the ability to possibly-maybe boost your mood. At the very least, the specimens we have are great for the fridge or the side of a file cabinet. They have a super-stylish and refined shiny-pewter look, and they’re each about 3/4" to 7/8" x 1/2" thick. Plus, they look super-cool in bunches. Takes about (25) of them to weigh 1 lb, and you’ll get a dozen per order. Never hurts to have some nice, small reliable magnets hanging around--especially these, which won’t lose their pull in your lifetime.

Triops: way cooler, bigger and more active than sea monkeys. They're dinosaur shrimp, leftovers from some 200 million years ago. Don't eat them; just grow them and enjoy this bizarre & ancient display of nature! In the kit you get a kidney-shaped tank 2-3/8" tall x 8-1/2"x 5-3/4", a very informative instruction booklet, and a packet full of triops eggs and food. In the starter pack/refill pack you get tripos eggs, food, conditioner and directions. Add the eggs to water and watch them go; they'll hatch in a day and reach 1" to 2" or more in a few weeks. Really easy to do, and really cool too.

These pretty, and pretty small, polished semiprecious stones include sodalite, tiger eye, quartz crystal, aventurine, amethyst, red jasper, fluorite, and rose quartz, plus a bonus assortment. You’ll get approx 1/2 oz of each in small corked bottles, 7/8” dia x 1-1/2” tall. The semiprecious pebbles are roughly 1/8” to 3/8” long.

Simple, yet clever 1" dia. by 3" long plastic device to demonstrate the vortex effect of a tornado. Partially fill with water one of the two half-gallon size plastic soda bottles which you supply. Screw the bottles into opposite ends of the tube which we supply. Tip so the full bottle is on top and give it a circular starting whirl. Presto! You have a vortex. Call it a tornado if you're a meteorologist, a Charybdis if you're a classicist, or a whirlpool if you're into oceanography. Lots of fun and a fine opportunity to attempt to explain the effects of the earth's rotation on water draining out of a bathtub. The phenomena are related we're told, but good luck!!

From the world of Metal Earth® Kits, the domain of the sure-handed, comes this museum-quality 3D steel Star Wars™ model of an Imperial Shuttle. Clip the shiny steel parts from their matrix and assemble them with a tweezers—no glue, solder, or anything else but a steady hand required. Finished piece will be approx 4” tall. For ages 14+ on account of they’re toughies to assemble, but worth the effort.

This is an excellent starter kit for learning the rudiments of Chinese brush painting. Includes a lavishly illustrated 47-page instruction booklet, an 11-1/8" x 8-1/8" pad with (36) practice sheets and a few sheets of xuan, the vellum-like paper that brush-painting artists use, plus 5ml tubes of Chinese watercolors in white, indigo, burnt sienna, carmine and gamboge, a saffron color. Also includes (2) brushes, an ink stone and ink stick, all in a nice boxed set.

The “I Dig It! Fossils” kit was the Oppenheim Toy Portfolio’s Platinum Award winner in 2018, and we think it's still a winner because fossils are really old anyway, and never go out of style. Unlike all the u-dig-’em-up fossil kits out there, this one features real fossils, in multiples. A color manual includes intros to fossils and paleontology, with instructions on making a grid and working slowly with the included metal-tip chisel, weighted hammer/pick and sponge. Fossils include snails and snail aggregate, stony coral, shark teeth and pre-amber resin. From Thames & Kosmos® and for ages 7+, especially those interested in how the pros do it.

Right after you build your own working medieval catapult or trebuchet. All you’ll need is glue, scissors and a steady hand (plus a small bag of marbles or rocks or something as a counterweight for the trebuchet) to construct these wooden, Canadian-made siege engine kits. The catapult stands 6” tall x 5” wide x 10” long and will toss assorted stuff 15 feet or farther, depending upon the stuff. The finished trebuchet will be 26” long x 18” wide x 24” tall and will propel small objects (meatballs?) 20 feet or more. Both include detailed instructions and are great resources for STEM activities. For ages 9+. Note: Please don’t propel small mammals, and please don’t put anyone’s eye out.

Could be a new line of cologne, but in fact, it’s a clever kinetic action demo kit called Wave Wires® with magnets marked for polarity, and mounted on (4) 8-1/2” long wires attached to a 4-1/4” square steel base. Includes a dozen 1/2” dia steel disc weights, an acrylic ring and an 8-page activity booklet. The attraction/repulsion magnetic properties cause the magnets to swing on top of the wires like old-time circus acrobats. Ages 8-14. Really cool, if we don’t say so ourselves.

When you peer through your magnifying glass at this specimen, or focus your microscope on it, even at the lower magnifications which work best, you're looking at one big bug. Make that (4) big bugs. The insects are real, encased in clear acrylic blocks 1-3/4" x 1-1/4" x up to 11/16" thick, and ready for inspection. Set 1 includes a scorpion, giant ant, wasp and a flower bug. Set 2 is a cricket, locust, yellow leaf beetle, and crab. No, not a crab louse or a crab spider, but definitely a crab ugly.

Build one yourself and learn about pneumatic and hydraulic technology in the process. The Thames & Kosmos® Mega Cyborg Hand kit is 2020 Astra Best Toys for Kids winner comes with a (52)-page color manual, (203) pieces and (5) experiments. The detachable thumb makes it left- or right-handed, although it's always going to have just (3) fingers, which is all robotic paws really need. Hand is adjustable to 160 degrees, and every finger adjusts to different angles, too, for precision movement. Control knob allows for up to 70-degree extension. No motors or batteries needed—just hydraulics and your own hand. You add some common household tools for assembly. Ages 7+.

We are so sorry. Due to incredible demand for this item it is sold out until 2021. We are very sorry for the hassles.

We’d start with triops, lovely little crustacean-ettes with compound eyes that have been around since Triassic days. You pick the Ghost Triops, see-through honeys, or the larger Gigantic Triops, the biggest of the triops which is gigantic among lesser beasts. In both cases you get eggs, baby and adult food, and a pipette. You add a bright light source, bottled natural spring water and a small tank. They hatch in a day or three, are full grown in a month or so, and have a life-cycle of up to 90 days.  Ages 8+.

Big hit in our youth, by Tommy James & the Shondells, but also one of the colors you might discover when you grow your Mystery-Color Crystal from this Thames & Kosmos® kit. Tommy and the boys also sang Crimson and Clover, so you have two chances to grow a Shondellian crystal. We bet you’d never have guessed that when you woke up this morning. For ages 8+.

Sometimes fun is like anything else—if want it done right, you have to do it yourself. The Bouncing Balls kit has a 1-1/4” mold, plus (4) packs of magic crystals in pastel colors to make (2) bouncing balls. Takes about (45) minutes from start to bouncing.

"WE DARE YOU!" by Vicki Cobb is a 322-page book for children, filled with over (300) scientific challenges and experiments that can be done with ordinary household stuff.
