Maybe. Could also be a stegosaurus, triceratops or something else--that’s part of the fun of paleontological parenthood. Just submerge the 4-1/2” tall ersatz dinosaur egg into cool water and wait 48-72 hours while it cracks like a real egg and the baby dino grows to a be a foot long. If your mother won’t let you skip your bath for a few days (they’re like that, mothers, no scientific discipline), just use any container bigger than a 12” dinosaur.
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. Our (25) piece set of polished gemstones includes: amethyst; howlite; tiger eye; hematite; amazonite; carnelian; sodalite; turqurenite; plain and rose quartz; rhodonite; unakite; snowflake obsidian; orange calcite; lemon jade; four varieties of jasper (serpentine; red, brecciated, picture and blue dalmation); and more. All approx 5/8" across.
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!!
The budding home scientist and
horticulturist will both delight in the ease with which this self
contained soil test kit brings discovery. The kit measures not only ph.,
but also Nitrogen, Phosphate and Potash content and contains material
for 40 tests. Since these are the essential ingredients affecting plant
nutrition, we see a science project in the making: experimental plant
growth in soils with different amounts of acidity and/or nutrients. From
Luster Leaf(tm), the kit is entirely self contained and includes
complete instructions for use and explanations. Be careful, please, the
kit does have chemicals and should not be used by young children without
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.
Make a whole bunch of fun and instructive Lego® machines/chain reaction models like marble runs and mousetraps involving ramps, buckets, funnels balances and much more. Comes with (33) Lego® elements, (6) Lego® balls, a dozen paper props, and a 78-page instruction booklet for (10) machines. You add a few common household items. Includes suggestions for more complicated devices if you have your own Lego® pieces, and if you don't, what are you waiting for? ! WARNING: CHOKING HAZARD–Small Parts. Not for children under 3 yrs.
Sort of like kleenex, because cellophane used to be trademarked but isn’t any longer so you can now say cellophane all you like. Cellophane, cellophane, cellophane. You’ll get (48) sheets of 12” square cellophane, a dozen each in red, yellow, green and blue, for teaching kids color mixing. But feel free to use them for anything. Includes instructions for making your own color paddle.
