Like the popular baking soda and vinegar experiments, this film canister rocket literally takes it to the next level by using that creation of gas and energy to jet off into the sky. If your explorer has seen videos of mountain tops getting blown off during a volcanic eruption, this science project is pretty much any space lover’s version. Get the building instructions over at kids science activity blog The Science Kiddo.

Each of our crates presents kids with a multi-faceted experience that can last for hours, or even days! Our crates include a magazine with additional science experiments and activities, and lots of rich content to dig deeper into the theme. We also provide online resources and video content for every project, all designed to allow kids to explore further.


It takes a few hours to see the results of this leaf experiment, but it couldn’t be easier to set up, and kids will love to see a leaf actually “breathing.” Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you’ll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.

This blood model experiment is a great way to get kids to visual what their blood looks like and how complicated it really is. Each ingredient represents a different component of blood (plasma, platelets, red blood cells, etc.), so you just add a certain amount of each to the jar, swirl it around a bit, and you have a model of what your blood looks like.
Any one of these simple science experiments for kids can get children learning and excited about science. You can choose a science experiment based on your child’s specific interest or what they’re currently learning about, or you can do an experiment on an entirely new topic to expand their learning and teach them about a new area of science. From easy science experiments for kids to the more challenging ones, these will all help kids have fun and learn more about science.
How are some dinosaur tracks still visible millions of years later? By mixing together several ingredients, you’ll get a claylike mixture you can press your hands/feet or dinosaur models into to make dinosaur track imprints. The mixture will harden and the imprints will remain, showing kids how dinosaur (and early human) tracks can stay in rock for such a long period of time.
There are many fun ways to get your children into natural science and Geodes are one way. This starter kit has 7 unique and fascinating ways to get discovered the mystery of the earth crust. Geodes are natural and a wonder to many who like to collect, but even as a one-off this is a great way to get kids thinking. This is fun and the breaking aspect always makes things interesting for those that need some initial enthusiasm.
With just a package of Starbursts and a few other materials, you can create models of each of the three rock types: igneous, sedimentary, and metamorphic. Sedimentary “rocks” will be created by pressing thin layers of Starbursts together, metamorphic by heating and pressing Starbursts, and igneous by applying high levels of heat to the Starbursts. Kids will learn how different types of rocks are forms and how the three rock types look different from each other.
Kids will love shooting pom poms out of these homemade popsicle stick catapults. After assembling the catapults out of popsicle sticks, rubber bands, and plastic spoons, they’re ready to launch pom poms or other lightweight objects. To teach kids about simple machines, you can ask them about how they think the catapults work, what they should do to make the pom poms go a farther/shorter distance, and how the catapult could be made more powerful. 

If you do this sidewalk constellation craft, you’ll be able to see the Big Dipper and Orion’s Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.
If your kids are curious about how animals like polar bears and seals stay warm in polar climates, you can go beyond just explaining it to them; you can actually have them make some of their own blubber and test it out. After you’ve filled up a large bowl with ice water and let it sit for a few minutes to get really cold, have your kids dip a bare hand in and see how many seconds they can last before their hand gets too cold. Next, coat one of their fingers in shortening and repeat the experiment. Your child will notice that, with the shortening acting like a protective layer of blubber, they don’t feel the cold water nearly as much.
Koala Crate is our line of science kits for kids ages 3-4. Introducing science and math to preschoolers may seem early, but in fact, it is crucial to building a strong foundation in STEM — science, technology, engineering, and math. Our crates introduce young learners to concepts like physics — through the science of rainbows — and biology — through learning about animals like reptiles and marine life.
Every child has different tastes and interests, but the products shown here were consistently popular with kids of all ages. We researched and reviewed over a hundred science kits and kids science experiments (and yes, had way too much fun doing it) and selected the very best ones. So no matter what kind of science lab kit for kids you're looking for - we've got you covered!
Chemistry Kits – Perhaps the most classic of the science kit options, these are great for kids who are interested in learning about how things work. There is a huge range of kits in this bracket, ranging in features and suitability. There is a chemistry kit for just about any child, and with a bit of research it’s easy to find one to suit your child’s age and ability.

This is the most kid friendly and fun lab kit you can get. My kids are ages 2 and 4 and cannot get enough of this. Everything in the kit is high-quality, and this kit lasts a very long time. We have done these experiments over and over for 3 months and only recently have used an entire bag of something. I admit to even being impressed by how cool the activities are. This is worth every single penny. I will 100% be ordering another kit when we deplete all the things in ours.
