Ten great science projects you can do with your kids

Throughout elementary, middle, and high school, science class was always the place we could count on having a little fun. Where else would we get the chance to build a volcano with vinegar and baking soda, conjure electricity from a pickle, or launch potatoes out of an air cannon?

Right now, though, children are at home all day, and parents and caretakers may be desperate for ways to keep their little gears turning. So we’ve prepared a full slate of activities to help you out: 10 hands-on science projects you can do with your kids. If you do one a day, that’s almost two weeks of educational fun.

Beyond the classic how-to, every experiment will come with an explanation of the scientific principles involved. That way, when your kid asks you why you’re making them cover their hands in shortening, you’ll have a good answer.

And don’t worry if you don’t have a potato cannon lying around: We’ve made sure everything you’ll need is both cheap and easy to find on your next trip to the grocery store. That is, if you don’t have supplies in the house already.

Check out the full shopping list below, plus the project schedule and the tools you’ll need for each one.
