35 Online Resources for Fantastic Free Science Videos for Kids and Teens

Because seeing is believing, especially when it comes to science.

Teachers know that the easiest way to understand new concepts is to see them in action. But you can’t always do hands-on experiments or demos in the classroom. Plus, some things just aren’t possible—like a trip to outer space or a deep dive into the ocean. That’s when you need a good source for free science videos. Our picks include short and long options for students from pre-K through high school. Enjoy the show!

With lots of quick clips, especially of fascinating animals, Discovery’s Instagram videos are winners for multiple ages.
