Holy Gadolinium, Batman, who discovered this Gd element? We're not sure, but he's close to our hearts, since Gd is a magnetic metal of the rare-earth group, and you know how we love rare earth magnets. This excellent 38-1/2" x 26-3/4" poster of the Periodic Table lists the elemental information about Gd and 117 other elements, and includes mini-biographies of (7) scientists. The full-color poster is not laminated, but is a good quality coated paper, and a fascinating addition to any classroom.

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.

That'd fill this 9-oz ceramic coffee mug with the periodic table of elements printed on the side to about half a cup. It's printed in color on both sides, actually, in case you're left-handed. The atomic numbers and weights are a trifle small, but then they are atomic.
