Quite A Kit
WARNING: CHOKING HAZARD-Small Parts. Not for children under 3 yrs.
We're really charged up about this modular Electronic Lab from Maxitronix(tm) that appeals to both girls and boys. The 4-in-1 set of interactive action kits includes colorful 5-1/2" x 3" x 1-1/8" plastic housings and components to build an electric bell, motor, generator and meter. As the manual says, they're "safe, solderless, educational and fun!" And the manual is the best we've ever seen. Every part and every step is illustrated and labeled (it doesn't presume you can tell an egg lug from a tapping screw), and it explains HOW each experiment works. Kids trying out the 10 suggested experiments learn to reverse a motor's direction, operate the bell or motor with the generator, use the meter to measure electricity and more. Requires (2) "AA" batteries (not included). This is an exceptional set for boys and girls aged 10 and up.

Magic Rocks
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.
