My children and I have worked our way through a LOT of science projects over the past few years, so I compiled them into one easy-to-find spot. If you’d like more ideas like this, you’ll love my best-selling book, TinkerLab: A Hands-on Guide for Little Inventors.

Most of these science projects and experiments will be engaging for children ages 3 and up, although I did MANY of them with my 2-year olds.

Enjoy!

    Hi Rachell
    I tried to get the recipe for the lava lamp, but couldn’t when I clicked on it. Can you send it to me? The one above with the oil and colors.
