Science for kids doesn’t need special equipment or a PhD. Easy, at-home science experiments can be done right in your own kitchen (or yard) and usually with ingredients you already have at home or can easily get. We’ve rounded up 24 classic concoctions, perfect for your curious crew. So get ready to make lightning, grow crystals and make slime. Plus, we’ve rated each experiment from one to five sponges so you know the messiness factor ahead of time. Click through the gallery to get cooking!

Film Canister Rocket 

A lesson in: Rocket science.
Like the popular baking soda and vinegar experiments, this film canister rocket literally takes it to the next level by using that creation of gas and energy to jet off into the sky. If your explorer has seen videos of mountain tops getting blown off during a volcanic eruption, this science project is pretty much any space lover’s version. Get the building instructions over at kids science activity blog The Science Kiddo.
