Zivko the Robot is back in stock! Our best selling STEM kit ever! Just call her (or him--it’s unclear and we don’t like to ask) “Zivko” because “the Robot” is her last name. Using just a screwdriver and side cutters, you build Zivko from this 107-piece S.T.E.M. kit. Set the mode for “Follow Me” or “Explore,” and Zivko will, yes, track you, or evade obstacles, respectively, via an infrared sensor and micro-controller programming. Interactive LEDs and sounds abound. Measures approx 5" x 5-1/2" x 6-1/2" when assembled with all (6) legs. You add (4) “AAA”s for power, which is the least you can do for someone this cute. Ages 10+.

Impressive, this 3-foot Lizard King. The 1:14 scale plastic model of a Tyrannosaurus Rex skeleton has 51 bones that snap together, then snap apart easily for later use, which is more than you can say about the original. Measures 36" long, and comes with a display stand. Bones are nicely aged for paleontological verisimilitude. Very nice kit, with legs, as they say! For ages 8 and up.

These here selenite wands are quite the specimens. You know selenite? It’s a variety of gypsum, and it’s mighty purdy and crystal-ish. You’ll get a wand of it, somewhere in the 5” to 8” long range, and maybe about a 1/2” on each side. Add a Laser Pointer and have some naturally ocurring fiber optic fun! Whatever else you do with it (besides look at it up close in amazement), is up to you. But you’ll always be able to say, “Want to see my selenite wand?”

Pop one of these roughly 1-1/4" dia stones into the toe of a sock, smash it with a hammer, and be the first person ever to see your real-as-Nature-makes-it geode!! Ninety percent of them have the familiar beautiful white crystals inside. Formed by volcanic action, they are found all over the world, but ours are from Mexico. There is no way to tell from the outside if they have crystal centers, but we will send you two just to raise your odds, and we haven't had a dud yet in our stores!! Much much more fun and satisfaction than buying one already cracked.

Lovely to look at, delightful to make jewelry out of or placed as shiny companions of small plants. Our (20) piece set of polished gemstones can include: Carnelian, Chrysocolla, Aventurine, Hematite, Lapis, Amazonite, Pyrite, Citrine, Amethyst, Tige Eye, Garnet, Mookaite, Indian Agate, Botswana Agate, White Howlite, Rock Quartz, Apricot Agate, Rose Quartz, Leopardskin Jasper, Blue Lace Agate, Turritella Agate, Yellow Aventurine, Dalmation Jasper or Orange Calcite. All approx 5/8" across.

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.

Our best and prettiest-ever slices of polished agate, showing concentric rings of natural and dyed colors. The slices range from 3" to 4-1/2" across and from 1/8" to 3/16" thick. We've seen samples from milky white to blue, purple, red, yellow and brown. No two alike, by definition. We'll choose. Think scientific specimens, framed art, coasters, trivets, paperweights, or skipping stones for rich kids who don't want to search the beach for flat stones.

Come on baby, do the Dinomotion! Dance if you like, but we’ll be here assembling this Jurassic Earth STEM kit from Engino®, and then we’ll be watching the dinosaur robots we’ve built doin’ their motion.

Comes with printed instructions for (2) models and you can find more theory, experiments and (3) more models with 3D instructions in the free app. Ages 8+.

Rock hammer with one squared chipping face and one pointy picking face, ideal for prospectors, rock hounds, construction and more. A single piece of forged and polished steel with a molded rubber grip makes this a solid and reliable tool that will last. 10-1/2" long x 6-1/2" across the 20 oz. head, 1-3/4 lbs. total. Well made. Good buy. Good bye!

Teaching a kid how to manage time—hey, that’s up to you—but this wind-up clock kit teaches kids the basic mechanical principles of gears and pendulums. Clock has a clear body, approx 7-3/4” dia x 1” deep with a 1/2” tall base, and individually colored gears for easy identification. It’s spring-driven, so no batteries are needed. Bell "dings" in 15-minute intervals. Tweaking the pendulum mounting, and tuning it, takes a little focus. Ages 6-10. ! WARNING: CHOKING HAZARD–Small Parts. Not for children under 3 yrs.

No need to limit the numbers you paint by. These kits all include 8” x 6” canvases, (6) acrylic paint pots, a #2 brush, color key and guide, plus tips for blending colors--a major improvement in the paint-by-numbers game. Packaging is also an easel, and becomes a self-adhesive hanger, which gives you a big leg up on the original artists. You pick: Van Gogh’s Starry Night; Sunflowers; Irises; Monet’s The Japanese Footbridge or Water Lillies.

No, that's not a contradiction. These are real arrowheads, made like the originals, but as replicas. You get a clear-plastic case with (4) of them, (2) made from jasper and (2) from obsidian. Sizes range from 1-3/8" long to approx 2". Has a short fact sheet, but no arrows.
