Kindergarten algebra is a lot different than high school. In kindergarten math, algebra means grouping like things, or noticing what doesn't belong in a set.

This recipe makes bubbles that not only blow up nice and big, but do tricks and experiments! How do you do it? It's not a secret, it's science!

Consult mechanics, automotive specialists for advice. Build a real engine or a scale model. Test and demonstrate its mechanical properties.

The garden is the perfect place to practice math and science with preschoolers. Get digging (and counting, sorting, observing at the same time!)

Learn about this simple machine and make a pulley of your own to use for fun science trials.
