Top 7 Science Websites for Kids

Science websites can give kids a great introduction to the exciting world of science, and there are many wonderful kid-friendly ones to check out. The best of these educational websites have kids learning about the world around them while having fun—and get them hooked on science and creative thinking in the process. Kids will discover lots of hands-on experiments to try, too.

4-H Stem Lab is a great first stop on your kid's science journey. There are dozens of experiments in areas such as chemistry, biology, math, and engineering. You'll find activities clearly marked for the intended grade level, as well as how long each one takes.

Each project also includes detailed, easy-to-follow, age-appropriate instructions, options for extensions, and challenge questions. Parents will love that each project includes a "messy meter" so you'll know what level of clean-up to expect, too.

How Stuff Works

How Stuff Works covers all sorts of interesting topics, from tech and culture to animals and quizzes, but head to the robust science section for articles on space, earth science, life science, engineering, and even paranormal science. Explore tornadoes, hair coloring, UFOs, radar, and lunar landings.

The site is geared more towards older audiences—the explanations may be too complex for younger kids on their own—but it's a great resource for families. Check out the "Science vs. Myth" area to dive into the truth about such topics as vampires and crop circles.

Since How Stuff Works isn't specifically intended for the youngest family members, parental guidance is suggested.

The Exploratorium

Whether or not you can visit the real Exploratorium in San Francisco, it's well worth a virtual trip. Part science museum, part art exhibit, the physical Exploratorium encourages you to touch, listen, see, smell, and sometimes even taste the world around you and their website takes that infectious, hands-on exploration online. It's a fabulous and fun resource for science learning and experimentation.

One favorite section is the "Accidental Scientist" area on the Explore tab. There you can learn more about the science of food—kids will especially love the section on candy. If you're looking for a different kind of treat, visit the "Snacks" section on the Education tab where you'll find bite-sized (non-edible) science experiments you can do at home.

Science Toys

Science Toys has instructions for crafting all manner of amazing gadgets from a solar-powered marshmallow roaster to the "World's Simplest Steam Boat." Most of them are best for high school students and above, although middle school students can enjoy them with some adult supervision as well.

These activities typically use inexpensive materials, but you may not always have them lying around your house (i.e., copper tubing, simple electrical components, etc.). Plan ahead when using this site and you'll certainly be in for a lot of fun.

Bill Nye

No list of science sites for kids would be complete without a link to Bill Nye, the Science Guy. His website helps reinforce the lessons learned on his iconic television show with experiments, explanations, and a dose of humor as well.

Click on the "Home Demos" section for a range of engaging experiments with cheeky names, such as "A Slice of Apple Fly," "How the Time Flies," and "Merry Poppings." All can be done with supplies you'll likely have on hand and are geared to kids of all ages.

Chemistry Activities for Kids

ThoughtCo's Anne Marie Helmenstine has compiled a great list of well-vetted, basic chemistry projects that are perfect for kids. Favorites include creating lava-filled volcanoes, liquid nitrogen ice cream, rock candy, and edible slime.

Make sure to read the directions first, as some activities will require special ingredients, need to be done outside, and/or require the help of an adult.

Science News for Students

Science News for Students keeps kids up-to-date on scientific trends. Written in an accessible, kid-friendly voice, the engaging articles help kids understand topics like the decline of the honeybee population and how police use forensics to solve crimes.

The site is most appropriate for upper elementary students and above, as some of the topics are too complex for younger children. But it's also a great way for parents to learn what's happening so they can help explain concepts to curious children. Plus, there's a lot of relatable science "magic" for little ones to love, too, such as an article on how to create snow like Elsa does in Frozen.
