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!
A lesson in: Polymers.
Is it a liquid or solid? The answer is both! This DIY slime—made from glue, borax and water—is also known as a polymer (molecules that can stick close together to be a solid or spread apart and take liquid form). And it’s all thanks to borax, which acts as a binder to prevent the glue from going completely liquid. Check out Explorable’s recipe on mixing the ingredients. Prolong the life of your goo by keeping it in an airtight container in the fridge.
