There are so many different kinds of science kits available for kids these days. Here, we will outline the main types so you can make a decision as to what best suits your child’s needs, interests and skill level. Children aged 5 years old want different science experiments and games than a child of 8 to 10 years old. The manufacturing guidelines are usually strict with what age groups can use these kits, so make sure that you don’t get your teen child something that should have been for a younger child.
This is an easy and fun kit to learn about science. Got it for a five year old. The concepts are easy to follow and so are the directions. Everything is pretty much provided in the kit in order to make the science experiments with the exception of some ingredients like vinegar or other acidic ingredients that can be easily found in one's pantry or fridge. You will need one paper plate and some Ziploc bags to store the powders provided after opening the package. For example - baking soda. Overall, we've enjoyed this science kit. My five year old asks to make a science experiment each day! Very fun and educational.
Penguins, and many other birds, have special oil-producing glands that coat their feathers with a protective layer that causes water to slide right off them, keeping them warm and dry. You can demonstrate this to kids with this penguin craft by having them color a picture of a penguin with crayons, then spraying the picture with water. The wax from the crayons will have created a protective layer like the oil actual birds coat themselves with, and the paper won’t absorb the water.
Refraction is when light changes direction and speed as it passes from one object to another. Only visible objects reflect light. When two materials with similar reflective properties come into contact, light will pass through both materials at the same speed, rendering the other material invisible. Check out this video from BritLab on how to turn glass invisible using vegetable oil and pyrex glass. 

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!

Did you know that a simple potato can produce enough energy to keep a light bulb lit for over a month? You can create a simple potato battery to show kids. There are kits that provide all the necessary materials and how to set it up, but if you don’t purchase one of these it can be a bit trickier to gather everything you need and assemble it correctly. Once it’s set though, you’ll have your own farm grown battery!
A step up from silly putty and Play-Doh, magnetic slime is fun to play with but also teaches kids about magnets and how they attract and repel each other. Some of the ingredients you aren’t likely to have around the house, but they can all be purchased online. After mixing the ingredients together, you can use the neodymium magnet (regular magnets won’t be strong enough) to make the magnetic slime move without touching it!
This simple experiment teaches kids about inertia (as well as the importance of seatbelts!). Take a small wagon, fill it with a tall stack of books, then have one of your children pull it around then stop abruptly. They won’t be able to suddenly stop the wagon without the stack of books falling. You can have the kids predict which direction they think the books will fall and explain that this happens because of inertia, or Newton’s first law.
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.
These sound like big words for our little ones, but there’s an easier way to break it down. Water and oil won’t mix because they’re not the same “weight” or substance (just like clay and LEGOs won’t become one). Now add a drop of food coloring (which is heavier than oil) and a fizzy tablet and watch the air bubbles take coloring with them to the top. Head on over to S. L. Smith’s blog to see how it’s done.
Watching a jet of foamy soda erupt from a bottle is not only fun, but also hysterical and will impress everyone around you… while hopefully not getting them (and yourself) too messy in the process. This also happens to be a really inexpensive home experiment, but you might want to invest in several bottles of soda and a bunch of rolls of mints just in case.

Homemade Kits – There are probably loads of objects around your home already, which can be used to set up your own science experiments. These include things like salt, baking soda, vinegar, soap, cornstarch and of course food dye to make things more interesting! You’ll also need some basic equipment like tweezers, ramekins or small tubs, a funnel and a dropper for example. There are too many home science experiments to discuss here, but with these basic supplies you’ll find you can perform some really cool experiments to amaze the kids!
A nature journal is a great way to encourage kids to be creative and really pay attention to what’s going on around them. All you need is a blank journal (you can buy one or make your own) along with something to write with. Then just go outside and encourage your children to write or draw what they notice. This could include descriptions of animals they see, tracings of leaves, a drawing of a beautiful flower, etc. Encourage your kids to ask questions about what they observe (Why do birds need to build nests? Why is this flower so brightly colored?) and explain to them that scientists collect research by doing exactly what they’re doing now.
The word “oobleck” comes from a Dr. Seuss story where a young boy must rescue his kingdom from a sticky substance. But the neat part of this experiment is how oobleck reacts to vibrations. Put the oobleck over a subwoofer (on top a cookie sheet!) and watch it dance to difference frequencies. Your dancer will see how sound isn’t just about volume! Check out more of this awesome experiment from Tammy of Housing a Forest.
The kit includes components that can be used to breed bacteria and experiment with genetic engineering. If you know a child who’re itching to investigate the field of genetics, then this product might serve as a great gift. The Thames & Kosmos Biology Genetics and DNA kit takes children on a journey through reproduction biology, chromosomes and cell components.

Don’t be crodsquinkled, as these dream potion experiments are the best way to bring the bizarrely brilliant world of the BFG to life. These easy to make concoctions will whizz, fizz and pop before your eyes, creating exciting chemical reactions that will have all kids squealing with delight. Again made using things you’ll find at home or can pick up from the supermarket, this is an easy project to try with the kids. Be warned though - this is one of the messiest science experiments for kids on the list!
Everyone can get ahold of a few potatoes, and what better way to use them (aside from consumption, that is) than to make them into an operating clock? It’s easy and only requires the use of a few things many people have handy, or, if you need to go to the electronics store to purchase an LED clock anyway, you can get the alligator clips and electrodes there, as well.
By building a lung model, you can teach kids about respiration and how their lungs work. After cutting off the bottom of a plastic bottle, you’ll stretch a balloon around the opened end and insert another balloon through the mouth of the bottle. You’ll then push a straw through the neck of the bottle and secure it with a rubber band and play dough. By blowing into the straw, the balloons will inflate then deflate, similar to how our lungs work.
Another physics kit that is sure to interest your child if they enjoy the Engino Newton’s Law Kit is the Klutz LEGO Chain Reactions Kit. This one teaches your kids about chain reactions and moving machines while also encouraging creativity and ingenuity by building their own. Plus it uses LEGO bricks they can play with when they’re done experimenting.

OST experiences also promote an appreciation for, and interest in, the pursuit of STEM in school and in daily life. They help learners understand the daily relevance of science to their lives, the depth and breadth of science as a field of inquiry, and what it might be like to choose to do science in the world, either as a professional or a citizen scientist.

The "volcano" was basically a miniature mound that fizzled. Could get a bigger reaction from dropping an Alka Seltzer in water or mixing baking soda with a little vinegar. The "giant crystals" only grew a couple of centimeters. All the experiments are on such a miniature scale it doesn't have any of the wow factor we were looking for. I will go back to googling fun experiments to do with my son.
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.
Lightning is essentially electrons moving uber fast between the sky and the earth—and with a few simple materials, you can use homemade static electricity (the reason behind your hair sticking up when you rub a balloon or go through a tunnel slide super fast) for DIY lightning. Figure how to recreate a family-friendly version of this spark by visiting activity blog Learn Play Imagine.
With a combination of a solid fuel source and a liquid oxidizer, hybrid rocket engines can propel themselves. And on a small scale, you can create your own hybrid rocket engine, using pasta, mouthwash and yeast. Sadly, it won’t propel much, but who said rocket science ain’t easy? Check out this video from NightHawkInLight on how to make this mini engine.
Ideal for introducing science-based activities to young children, Cassie’s experiment for mixing colours and water is a simple science experiment designed for preschoolers. Let your little one choose which colour to use when, ask them to describe the colourful shapes they’ll see dancing in the water and see what happens when you mix more than one colour together.
Science is a wonderful thing for kids! There is so much to learn and discover right around us. Many science concepts start in the kitchen with simple materials you already have on hand. Fill a plastic tote with easy to find supplies and you will have a homemade kids science kit filled with learning opportunities that are sure to keep them busy all year long!

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.
The products listed here may contain small parts that are choking hazards for children! Toys can pose a hazard to babies and young children – they can choke, suffocate, or otherwise harm the child. Young children explore their world by putting things in their mouths, but children under three years of age do not have a well-developed coughing reflex and will choke easily on small items. All children, regardless of age, need close supervision with any toys to help prevent accidents from happening. Adult supervision is required at all times!
My First Mind Blowing Science Kit also comes with cool scientific tools like test tubes, pipettes, stirring sticks, and measuring scoops that will make your child feel like a real chemist. Not only will they learn important skills in conducting experiments, they will also learn the basics of acids and bases. While none of the experiments are particularly messy, it’s safer to perform them on a flat surface with adult supervision.

There is a wide range of price and quality, which is normally reflected on each other and the higher the price the better the quality. However, kids are surprisingly happy with what they get and if the budget is low to make sure you’re enthusiasm is high. Kids love when you get involved and make the science magic happen, so ideally get enthusiastic.

Find out how plants “drink” water with some food coloring. Use carnations, roses, or stalks of celery submerged in the colored water and watch the liquid slowly seep through the plant’s “veins” and towards the leaves. Keep an eye out -- you could have a very colorful bouquet just after the first day. Get the rundown by Dad’s Book of Awesome Science Experiments over here.
Tinker Crate develops kids' natural creativity and curiosity using STEM ("Science, Technology, Engineering, and Math") principles while saving time for busy parents. Our mission is to help kids use STEM as a key to creative problem solving, a foundation for critical thinking, and a pipeline to innovation. Your monthly crate includes all the materials and inspiration for science and engineering projects such as: trebuchet, paper circuits and zoetrope.
Kids ages 5-8 are at a crucial time in their understanding of science, math, and engineering. They're old enough to grasp how big ideas like the solar system and flight, things that perhaps once seemed magical, have scientific properties that allow us to explore outer space and build rocket ships. Kiwi Crate allows children in 1st, 2nd, and 3rd grade to begin a hands-on discovery of physics, chemistry, biology, and more, with fun projects that they can assemble themselves.
Baking soda volcanoes are one of the classic science projects for kids, and they’re also one of the most popular. It’s hard to top the excitement of a volcano erupting inside your home. This experiment can also be as simple or in-depth as you like. For the eruption, all you need is baking soda and vinegar (dishwashing detergent adds some extra power to the eruption), but you can make the “volcano” as elaborate and lifelike as you wish.
This celery science experiment is another classic science experiment that parents and teachers like because it’s easy to do and gives kids a great visual understanding of how transpiration works and how plants get water and nutrients. Just place celery stalks in cups of colored water, wait at least a day, and you’ll see the celery leaves take on the color of the water. This happens because celery stalks (like other plants) contain small capillaries that they use to transport water and nutrients throughout the plant.
