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.

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.

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.

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.

From Brazil, rescued from the guts of quartz crystal antennae, these clear rock crystals are pebble sized (some maybe 3/8" long, most smaller). We're thinking classrooms and microscopes, small jewelry items, or, at these prices, a nice little bowl of crystals for the table. Each small box contains approx 2-1/4 oz of crystals.

This is an excellent starter kit for learning the rudiments of Chinese brush painting.

Geology for those with short attention spans? The original Magic Rocks®, of course! Mix the solution in a jar of water, drop in the pebbles, and watch them grow into a forest of multi-color stalagmites. Growth starts in 10 minutes, is impressive in 30 minutes, and complete (up to 4" tall) in 2 hours. Extra credit if you can make it grow stalactites by gluing the pebbles to the bottom of a jar, then pouring the solution in and turning it upside down. Who knows? Maybe it will work. Comes with a set of marine decals to decorate the jar. Definitely not for use with living fish. For ages 10 and up.

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 supervision.
