Everything you need to build a little DC motor is included in this kit (except sandpaper, screwdriver, scissors and, of course, an AA battery). The instructions are simple and explain the theory as well as assembly. Fun and educational for ages 12 and up.

Can you say orrery kit? That’s what this is to an astronomer. (Named for Charles Boyle, 4th Earl of Orrery in County Cork.) Your orrery has the sun and planets out to Neptune on a gear-driven 6” x 4” base. You’ll get all the parts, plus (8) paint pots and a brush. The finished model will be approx 12” wide x 4-1/4” tall. For ages 8+.

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.

Sometimes if you want something done right, you have to do it yourself, and that often applies to kaleidoscopes. Build your own 10” version and fill it with trinkets and baubles to create a personalized dazzling vision. Comes with a paper cone, eyepiece, holographic foil, glow stars, beads, crystals and detailed instructions. Yes, you can add your own baubles.

This is your classic dual-threaded connector tube to link a pair of plastic bottles together, demonstrate tornado action and learn once and for all about the fluid dynamics concept of a vortex. In an homage to Dorothy in Kansas, this connector tube also comes with a tiny cow and a barn included. Also a lot of glitter, which we suppose is Oz-like. Includes instructions and a surplus-inducing QR code (to see a video) that's as dead as the Wicked Witch of the West.

From Fascinations®, these small model kits are made from intricately laser-cut polished steel. Punch the pieces out from the 4-1/4" square sheet and put them together with the tiny tabs. You pick the dragonfly, with a 4-1/2" wingspan or the Black Pearl pirate ship, approx 3-1/2" long. For ages 14+, because they take plenty of small motor skills.

Physics faculty alert: It's very small, but teaches a powerful lesson, this little diamagnetic-properties demo kit. You get (4) plated magnets, each 1/4" square x 3/32", and (2) 1/4" square pieces of graphite to float above them. The graphite may have slight chips along the edge but that won't affect the effect. Includes instructions/fact sheet.

Learn how they did it in Hawaii Five-0 (look it up or ask your parents) every time Danno booked ’em. No crime required for this Fingerprint Verification Set. Comes with a 2" dia magnifier, ink pad, fingerprint powder, dusting brush, blower, goggles, tape, (5) 3-1/2" x 5-1/2" fingerprint cards, fake credentials, (5) 3” x 5”evidence cards and a (7)-page booklet. Ages 10+.

Now your kids can practice wilderness survival in the safety of their own home. This KidzLabs™ Survival Science Kit includes (30) pieces that will teach and demonstrate the science of wilderness survival, but hopefully won’t be actually required to save someone’s life. It’s always good to practice, though. Contains components to make a telescope, sundial, torch, Morse code flashlight (Batt. included), water purifier, compass, reflective mirror, whistle and magnifier. Comes with a carrying case, too. We’re not going to tell you how to parent your kids, but if you want to drop them off in the woods for their own good, we saw nothing. “Hey, where’d everyone go? Well, at least I have this Survival Science Kit!” Ages 9+. ! WARNING: CHOKING HAZARD–Small Parts. Not for children under 3 yrs.

Our robotic kingii dragon (Chlamydosaurus kingii, or frilled-neck lizard) is better than a puppy because you don't have clean up after it and it won't chew the furniture. This STEM education kit has (2) motors and digital control via IR sensors to activate LED eyes, motorized mouth and pop-out neck frill, plus "Escape" and "Chase" modes, which make it retreat and follow you using IR sensors, respectively. You'll need (4) "AAA" batteries and some patience, as this kit is delightfully challenging. Finished dragon will be 13-1/2" long x 8-1/4" x 5". For ages 10+.
