6. The Shiny Pennies Experiment

We included one classic experiment to our list of science activities for toddlers and preschoolers. Together with your kid, collect as many old tarnished pennies you can find and put them all in one container. Pour in the vinegar and soak the pennies. Pretty soon, they will become shiny and will look new. This experiment might also work with other solutions like lemon juice so you can try that one, too.
