Do you love science experiments for kids? We totally do and want to help you love them too!
Doing simple science experiments at home or in your classroom is the easiest way to teach kids to be problem solvers and critical thinkers and help them develop a curiosity about the world around them. These skills empower kids to be confident in their ability to handle life’s challenges which is a life skill that cannot be overrated!
Plus they are a ton of fun to do and a great way to make memories with your family. Ready to get started? Here are some of our most popular and very favorite science experiments for kids to do!
If you are a long time reader of Coffee Cups and Crayons (high five!) then you already know that we strongly believe in simple fun and learning. You probably already have most of the supplies needed for these experiments in your kitchen cupboards right now. Which is important because it doesn’t matter how cool the science experiment is, if it’s not do-able it will just end up being an image that sits on your Pinterest board forever.
Speaking of Pinterest, you’ll want to make sure to pin this page to your favorite board. There’s a ton of experiments on here that you can keep coming back to when you’re looking for a new idea. We’ll also continue to add to this list as we post new ones to make this the best list of science experiments ever!
