One of the best ways to channel kids’ innate curiosity is through the wide world of science. Why is the sky blue? What makes WiFi work? I could go on, but I don’t need to because there are so many awesome science websites for kids out there just waiting to be explored!

We can all agree that it’s important to encourage kids to find answers, even to big questions, and you never know: they could stumble upon something that inspires them to learn even more. 

Of course, these days many parents are looking to have less screen time, and with so many tools to juggle for virtual learning, we don’t want to pile on more tech to track. 

But that’s the beauty of these science websites—they are free (or mostly free) to use, and their interactive resources are designed to get kids and teens excited about the world around them. Not only is the screen time educational, it’s designed to get kids thinking about the natural world and innovations beyond just flipping through social media or Netflix. 

Best Science Websites

Not sure where to start?

Enrichment activities like taking a virtual science field trip or watching a powerful documentary with your student might help identify what branch of science they’re most interested in. Plus, an amazing virtual expedition or awe-inspiring documentary can be motivating and make the science real for kids. 

Best Science Websites for Elementary and  Middle School Students

From learning why dogs wag their tails to online tours of paleontological digs and spaceships, these websites are sure to intrigue elementary and middle school students. 

They also present plenty of academic content in a fun way, so why not try a game or interactive investigation to supplement what they’re learning in school?
