20 Awesome Science Kits for Kids to Build, Explore, and Experiment at Home
We've been told for years that we need to give our children STEM toys to make them successful in life, but what does that mean after we've bought them Lego sets, robots, and dolls dressed as doctors? If you're really interested in piquing their curiosity about science, a kids' science kit is the way to go. When they're able to make a volcano erupt, hatch butterflies, and grow crystals—with an adult's help, usually—kids will start to love biology, physics, and other sciences as much as they love cars, video games, magic, and mermaids.
Kids' science experiment kits not only provide hours of at-home entertainment, but your kids will actually learn about stuff like chemistry, paleontology, electrical currents, crystals and geodes, and even climate change—all while having fun.
Since you probably don't want your 5-year-old to be mixing chemicals and your sixth grader may be so over dinosaurs, we've found kindergarten science kits, molecular chemistry models, and more kits for kids of all ages. Some may want to do the grossest possible experiments at home, while others want to create beautiful things by way of science. If, after enjoying one of these kits, your kid gets really into these subjects, you may also want to look into getting a science subscription box from KiwiCo. That way the fun (and learning) never has to stop.
Have a look at our 20 top picks for the best science kits for youngsters of all ages.
Note: Some of these activities contain chemical substances and require adult supervision.
Ivy Step Dinosaur Fossil Dig Kit
Encourage your budding paleontologists to chisel away at eggs to discover 12 (miraculously preserved) tiny dinosaurs. To make this less frustrating for younger dino fans, you can soak the eggs in water and make the egg substance a little easier to hack away at. The kit includes chisel tools, a magnifying glass, a flashlight, and full-color excavation cards with facts about each species of dinosaur they'll uncover. Ages: 4 to 8.
KiwiCo Science of Cooking: Ice Cream
KiwiCo's monthly subscription kits are one great way for your kids to get a regular dose of STEM learning disguised as play. But if you're not into that kind of commitment, they also sell one-off kits like this ice cream-making project. They'll learn about crystals, freezing points, and food stabilizers while also making some delicious dessert to share with the family. Instructions and equipment are included, but you'll need to buy the ingredients separately. Ages: 5 and up.
National Geographic Super Gross Chemistry Set
Some kids are just more motivated to pay attention when there's the promise of something gross—and if you have one of those, you already know this. National Geographic harnesses that interest in this kit that contains instructions and equipment for 15 different gross experiments with themes like boiling boogers, farting slime, and test-tube vomit. The booklet also has instructions for an additional 30 experiments, for those whose scientific curiosity keeps on going. Ages: 8 and up.
Abacus Brands Bill Nye's VR Science Kit
While we can't exactly have Bill Nye over to our homes to teach science to our kids, the VR headset in this science kit provides the next best thing. Download an app to your phone and Nye will pop out of the included spiral-bound project book to explain the scientific principles behind each of the 30 science projects. Not to downplay your own instructional skills, but it really is more fun when he does it. Much of the necessary equipment is included, but you will need to use some typical household items as well. Ages: 8 to 12.
Old Nobby Organic Chemistry Model Kit
The words "organic chemistry" may strike fear into the hearts of most adults who weren't science majors. That's because we never had a toy/study aid like this kit from Old Nobby. The snap-together three-dimensional models are originally meant for high school and college-level students to learn and remember specific molecular structures, but the beauty of a kit like this is that even younger kids can understand and have fun with them on a very basic level. That means they can approach chemistry without fear in the years to come.
