Collection: STEM Toys & Science Experiments

Science toys for kids do not need a kit with 40 parts. The best ones demonstrate a single idea so clearly that a child can explain it back to you. That is the test for this collection.

Physics toys. The balancing bird balances on a fingertip, a pencil, a nose: center of mass, in one object. The gyro wheel and rail twirler show magnetism and angular momentum, and light up while they do it.

Electricity. A plasma ball is a science lesson that lives on a desk. Touch the glass and the lightning follows your finger. Ours come in 3, 6 and 8 inch sizes.

Chemistry and biology. Water growing toys absorb water and expand up to 600 percent, then shrink back when dry. Measure them each day and you have a growth chart.

Ages 6 and up for the physics toys, 8 and up for the plasma balls. All of them make good science fair starters and STEM classroom prizes.
