In the age of iPads and smartphones, it can be a difficult task making sure that your kid is being properly engaged. Video games, while a lot of fun, don’t always provide the kind of intellectual stimuli that the growing brain requires.

The best science kits for kids are not only educational, but can be just as enthralling as the best video games out there. They also can provide the inspiration and foundation for a lifetime love of science, which can lead to more than just a hobby.

In fact, according to the Pew Research Center, STEM-related jobs have grown by a staggering 79% since 1990. That means that setting your child up for success with STEM skills is something that they may thank you for down the line.

Snap Circuits Classic SC-300 Snap Circuits Classic SC-300 Electronics

There are over 300 experiments available here, which means that there are probably countless hours of entertainment and education all in this small package. While an electronics kit might sound a bit advanced for the recommended age group (8 & up) it is actually tailor made to be safe and easy. All the components snap together, which means that no tools or soldering is needed. And, when your kid inevitably checks off every project on the list, upgrades and expansion kits are available to keep the fun going even longer.

Creativity for Kids Grow ‘n Glow Terrarium

The wonders of nature have perhaps never been closer than they are with the Grow n’ Glow Terrarium from Creativity for Kids. Here is a product that is aged from year 6 and up, though it is safe to say that it can provide both education and entertainment for amateur biologists of any age. Inside the package is everything needed for two full terrarium plant cycles. That means potting mix, chia and grass seeds, river stones, and even a mister to keep everything watered. The real strength of this product is that it’s both scientific and artistic … kids can both design their own ecosystem using the included decorative elements, then grow their own plants inside that ecosystem, learning all about the life cycle of plants in the process.

4M Crystal Growing Experiment

Crystal growing was always one of my favorite experiments growing up, and for good reason. Watching the real-time formation of crystalline structures in your own home is incredibly exciting for all ages. It keeps kids engaged with the process, as they wont be able to help checking in on their crystal’s progress as often as possible. There are seven different crystal growth experiments included in this remarkably well-priced kit. The young geologist-to-be in your family will appreciate learning about mineral structures, while most kids will simply enjoy watching these colorful crystals grow. One top feature that didn’t used to come with these kits is glass display cases for the crystals. Back in the way we had to use mason jars, but these are much cooler and feel more scientific.

That’s because this Mega Gemstone Dig Kit gives kids creative access to 15 different real gemstones, whereas most crystal growing kits only have one or two. This is a more specialized kit that is perfect for the kid who is into rocks or geology, though there is no doubt that this kinds of excavating will likely be a thrill no matter what they happen to be interested in. A full color learning book is included. Kids can learn all about how different crystals are formed and mined, as well as how to identify these more common crystals in the wild. Each kit allows for the expedition of 15 gemstones, so if you have multiple youngsters you might want to invest in multiple kits.

Stomp Rocket Dueling Rockets

Okay, so we have to start by admitting that there is not technically a whole lot of science going on behind the DUELING ROCKETS kit by Stomp Rocket. Sure, there is a very simple lesson about air-powered propulsion, but it’s doubtful that your kids will see this one as a science experiment. Instead, they’re going to see it for what it actually is … hours of fun rocket-based activities. The box claims a full 200ft firing distance, but the motivated youngster will probably be able to beat that. What we have always loved about Stomp Rocket is that it is, as advertised, 100% kid-powered, which is another way of saying that it is actually going to provide some exercise along with all the entertainment.

Insect Lore Deluxe Butterfly Garden

A personal butterfly garden is not something the we ever had access to as children, so the thought of being able to watch live caterpillars transform into butterflies is an exciting one, even now. This kit actually comes with 10 live caterpillars. By putting these caterpillars into the included chrysalis stations, kids can watch as their small bugs transform magically into butterflies over the course of the next few weeks. While this is certainly one of the most exciting toys for kids interested in bugs & biology, there can be some complications in ordering an account of there being live caterpillars in the box. The manufacturer recommends only placing an order if the daytime temperatures in your area are between 55F and 85F, otherwise your little caterpillars might not survive the trip.

Operation Game

It’s pretty amazing to see that one of the oldest and most cherished board games of the last century is still performing well with younger generations. OPERATION, the classic game of playing doctor, gives kids a chance to test their hand / eye coordination by performing mock surgery on a cartoon named Wally. What could possibly be better than that? Operation is a great game to be played with others or by yourself, so it is a popular go-to for rainy days and birthday parties. Whether or not it will inspire a career in the medical industry is somewhat more ambiguous.

The VERDICT: Best Science Kit for Kids in 2023

It’s actually a lot easier to get a kid interested in science than an adult. As we grow up, our minds become more and more set in their ways, to the point where learning new things becomes something of a snore.

Kids, however, have beautiful little minds that act like sponges to the realities and mysteries of the world around them. The best science kits for kids are the ones that take advantage of this mental openness to instill not only a passion for science, but a dedication to scientific thinking and principles.

In terms of overall STEM value, we absolutely love the Big Bag of Science Works by BeAmazing! Toys. It has a lot of components to keep the kids busy and is super portable and easy to work with.

However, if your child is becoming more interested in science and you think that you’d like to encourage them further, the AmScope Beginner Microscope is a great way to help them along their scientific journey.

Buying Guide: How to Choose a Science Kit for your Kids

The 20 science kits for kids that we have reviewed here constitute only a small fraction of what is available on the market. In fact, the business of kids science toys is actually experiencing a big boom, which is a good thing for any parent concerned for their child’s intellectual development.

The hard part is finding the right kit for your own child. We’re taking a closer look at what exactly it takes to make a great science kit, and the things you should consider before you make your purchase.

Recommended Age Rating

With science experiment-based kits, it is very important to double check the recommended age for each product before you buy. The reasons for this are twofold.

Firstly, some young children should not be exposed to the small parts and chemicals that are often included. Because many things are hazardous to younger children, it becomes very important to keep certain things away from them.

Secondly, you don’t want to go too far the other way, either. A child who is not challenged by their science experiments will likely not be engaged with them, the the chances that they abandon science altogether goes up.

Ages 3 to 6

Kids at this are more likely to be engaged by activities that grab their immediate and physical attention. They like to smell, hear, taste, and touch, so getting them a kit to go along with that is a good idea. Baking soda volcanoes and slime kits are both easy to enjoy and safe for even youngsters, and with adult supervision, some basic crystal experiments as well.

Ages 7 to 10

At this age, you’re going to want to find a science kit that helps prepare your child for the science classes that they will most certainly be taking in middle school, high school, and beyond. Generally this means looking for experiment kits that teach things like the scientific method, or that have included educational workbooks that help explain the concepts behind the experiments themselves.

Ages 11 and up

When your kid reaches this age they might need some slightly more advanced projects in order to keep them engaged with the material. Things like electronic kits are a good option because they require increased hand coordination and dexterity, two things that are in development in the brain during these years.

Other Materials You’ll Need

You should be advised that many of the science kits listed on our review do not come with 100% of the things needed to complete the experiments. For instance, many kits require common household items like baking soda, distilled water, cups & plates, or even lemons & potatoes to get the experiment done properly.

You don’t want to wait until play day to find out that you’re missing something important, so be sure to check the product specifications, and if available, the experiment handbook to see what it is that you’ll be needing.

The Different Types of Science Kit

As you have probably picked up on by now, there are more than a few different areas of specialty that are available with science kits. Whether you’re looking for an all-around science kit that has a bit of everything, or you need that perfect kit for the kid that knows exactly what they want, it helps to know a bit about what kind of experiments are available.


For the rock & mineral oriented youngster, there are a few different popular experiments that you can choose from. The most popular include crystal kits in which simple salts are blended with solutions to create a self-growing crystal formation. These are great for kids of all ages. And rock candy, of course, is delicious.


Our favorite astronomy science kit of the year is the Solar System Planetarium from 4M. It lets the kids build and decorate a scale model of the solar system, or, if they prefer, create an entirely new solar system of their own.

In addition, there are a lot of stargazing kits out there that teach about constellations, navigation, and more.


Children are natural born biologists. They have a built-in curiosity for all things slimy, creepy-crawly, and wild. A biology based science kit is a great way to stimulate and encourage your child’s natural wonder for the world around them.

Butterfly kits, jar gardens, and simple aquariums are a great place to start, though be mindful if you are ordering any live insects through the postal system … they often times do not survive extreme temperatures.


You’ll be hard pressed to find a young boy or girl who isn’t interested in seeing explosions, and that (to a safe extent) is what you get through the magic of chemistry. Everything from foaming volcanoes to fizzy rocket launchers are available to teach about simple chemical principles and reactions.

For the slightly more advanced youngster, a beginner’s microscope is a heck of a gift indeed.

Frequently Asked Questions (FAQ)

Q: What is a good age to introduce children to science?

A: It is never too young to start teaching your child about science! While there are certain experiments and toys that are not appropriate for very young children or infants, there are products designed especially for this age range that do not feature swallowing hazards or anything like that.

Q: What’s a good science kit that both boys and girls will like?

A: It used to be common thought that what would be popular with boys would not be popular with girls, and vice versa. However, this mode of thinking has become outdated, and it is likely the reason that girls have been less interested in pursuing STEM-related careers for so long.

In fact, in most studies on the subject, girls performed as well or better than their male counterparts in math & science, despite the discrepancy.

Q: Can kids use these science kits without adult supervision?

A: While some of these experiments and kits are much simpler than others, it is always best practice to review the experiments and materials yourself before allowing your child to perform them unobserved.

Generally speaking, these kits are made to be as safe as possible and rarely have any toxic or dangerous chemicals. Still, kids can be kids, and they can make a mess of just about anything if you’re not paying attention.
