Can you make water float? We bet you can. No, you don’t need to be a wizard or a witch. You don’t need to cast a spell. There’s nothing magic about it at all, in fact. You can make water float using good, ol’ fashioned, awesome science. The “trick” to this experiment is air pressure. Get everything you need and the how-to, right here, thanks to Mike Adamick and his book, Dad's Book of Awesome Science Experiments.
Making a borax snowflake is a crystal-growing project that is safe and easy enough for kids. You can make shapes other than snowflakes, and you can color the crystals. As a side note, if you use these as Christmas decorations and store them, the borax is a natural insecticide and will help keep your long-term storage area pest-free. If they develop a white precipitant, you can lightly rinse them (don't dissolve too much crystal). Did I mention the snowflakes sparkle really nicely?
This grow-your-own experiment that lets you grow crystals inside an egg shell. Be sure to get alum powder that contains potassium, or else you won't get any crystal growth. Adding drops of food dye to the growing solution yields some super cool crystals. A perfectly formed geode takes about 12-15 hours to grow, making this a great weekend project.

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.
Below are 37 of the best science projects for kids to try. For each one we include a description of the experiment, which area(s) of science it teaches kids about, how difficult it is (easy/medium/hard), how messy it is (low/medium/high), and the materials you need to do the project. Note that experiments labelled “hard” are definitely still doable; they just require more materials or time than most of these other science experiments for kids.
If your snacker has noticed how their apples have turned brown after being left out for too long, then they’ve seen oxidization in action (loss of electrons and nutrients when in contact with oxygen). Fortunately, lemon juice only oxidizes when in contact with heat. This method works with baking soda and milk too. Click here to find out how to write secret messages with your little spy.
There is a clear line between experimenting with a homemade science kit and one that is paid for. I like both, but it is easier for children to use and be left to their own devices with the kits that come boxed up. These have all the equipment needed, usually labeled and comes with clear, distinctive and easy to use manuals for conducting the experiment.
Your whistler has the basics of air pressure down just by using their mouth to blow. And now you can amaze them with this egg-cellent experiment. There is a little fire play involved (dropping a lit paper into the bottle), but that’s what causes the unbalanced air pressure, which pushes the egg into the bottle. Want to test it out? Head over to The Scientific Mom and get the step by step.
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.
This experiment teaches kids about weather and lets them learn how clouds form by making their own rain cloud. This is definitely a science project that requires adult supervision since it uses boiling water as one of the ingredients, but once you pour the water into a glass jar, the experiment is fast and easy, and you’ll be rewarded with a little cloud forming in the jar due to condensation. 

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.

You won’t want to do this experiment near anything that’s difficult to clean (outside may be best), but kids will love seeing this “elephant toothpaste” crazily overflowing the bottle and oozing everywhere. Pour the hydrogen peroxide, food coloring, and dishwashing soap into the bottle, and in the cup mix the yeast packet with some warm water for about 30 seconds. Then, add the yeast mixture to the bottle, stand back, and watch the solution become a massive foamy mixture that pours out of the bottle! The “toothpaste” is formed when the yeast removed the oxygen bubbles from the hydrogen peroxide which created foam. This is an exothermic reaction, and it creates heat as well as foam (you can have kids notice that the bottle became warm as the reaction occurred).

Biology is an important area of science because it teaches us about our bodies and the environment around us. With this Thames & Kosmos Biology Genetics and DNA Kit, your child will jump into the world of heredity and variation of organisms by using a test tube to isolate tomato DNA. This in-depth kit is fun and it covers so many areas of biology that most kits don’t cover.


Is it a liquid or solid? The answer is both! This DIY slime—made from glue, borax and water—is also known as a polymer (molecules that can stick close together to be a solid or spread apart and take liquid form). And it’s all thanks to borax, which acts as a binder to prevent the glue from going completely liquid. Check out Explorable’s recipe on mixing the ingredients. Prolong the life of your goo by keeping it in an airtight container in the fridge.
This is an easy experiment that’ll appeal to kids of a variety of ages. Just take a zip-lock bag, fill it about ⅔ of the way with water, and close the top. Next, poke a few sharp objects (like bamboo skewers or sharp pencils) through one end and out the other. At this point you may want to dangle the bag above your child’s head, but no need to worry about spills because the bag won’t leak? Why not? It’s because the plastic used to make zip-lock bags is made of polymers, or long chains of molecules that’ll quickly join back together when they’re forced apart.

Let’s be honest, we’re all secretly waiting for the hovercraft to be a bonafide mode of transport, but in the meantime why not try this Balloon Hovercraft experiment at home? Using just a balloon, a bottle cap and a CD, you’ll be able to create a hovercraft that glides across the table to move, and with just 3 easy steps to follow, it’s perfect for a quick at-home activity.
It’s natural to have a lot of questions about the world. As you wonder about these things and ask questions, you are learning. Curiosity about science helps you become an explorer finding out how things work and why things happen. Anyone can be a scientist, performing experiments to ask questions and get answers. You can even be a scientist at home, working on experiments with ingredients you probably have in your kitchen or laundry room. Always get a parent’s permission before you conduct experiments. Working as a team with an adult is best for safety.

Sir Isaac Newton discovered many integral concepts that are important for scientific discovery today, and this kit teaches them all: inertia, momentum, kinetic energy, and potential energy. This Engino Newton’s Law Kit is perfect for the kids who are very hands-on and like to build things. Your kids will understand how classical mechanics works by constructing their own catapult, balloon powered plane, drag racing car, crash car, and more.

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.
Younger children are most likely to be interested in something which is very hands-on, and gives results quickly. They probably won’t be interested in growing a crystal, and are probably a bit young for something like a robot building kit. Young kids will be most likely to enjoy a gross science kit, or a volcano kit. Also think about safety features when buying for younger children. Make sure they won’t eat anything they shouldn’t, or there are no small parts which could be dangerous.

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.
You could even step into the living room to have more scientific fun. Learn about static electricity with some tiny scraps of paper and a balloon. Blow up the balloon and tie it closed. Make a small pile of paper scraps on the floor, and rub the balloon back and forth several times on your hair or on a sweater. Immediately move the balloon to the paper and watch as the paper scraps cling to the balloon. Rub the balloon on your head or sweater again and then place it against the wall to see it stick there. This surprising sticking happens because you have moved electrons around and the balloon now has more of a negative charge, while the paper or the wall has more of a positive charge. Putting the two surfaces together makes the opposite charges stick to each other.

It takes about a week for the crystals of this rock candy experiment to form, but once they have you’ll be able to eat the results! After creating a sugar solution, you’ll fill jars with it and dangle strings in them that’ll slowly become covered with the crystals. This experiment involves heating and pouring boiling water, so adult supervision is necessary, once that step is complete, even very young kids will be excited to watch crystals slowly form.

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.


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.

For this saltwater density experiment, you’ll fill four clear glasses with water, then add salt to one glass, sugar to one glass, and baking soda to one glass, leaving one glass with just water. Then, float small plastic pieces or grapes in each of the glasses and observe whether they float or not. Saltwater is denser than freshwater, which means some objects may float in saltwater that would sink in freshwater. You can use this experiment to teach kids about the ocean and other bodies of saltwater, such as the Dead Sea, which is so salty people can easily float on top of it.

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.
'Tis the season for gumdrops and this classic structural engineering challenge uses just two ingredients: toothpicks and candy. We’re particularly fond of this one from The Homeschool Scientist because it helps you explain what the concepts (engineering, load distribution, physics, shape comparison) are to your kiddos while they are building it. doing it. Visit The Homeschool Scientist to get going. And click here for five more gumdrop-themed challenges. 

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.


If your kids are learning about genetics, you can do this edible double helix craft to show them how DNA is formed, what its different parts are, and what it looks like. The licorice will form the sides or backbone of the DNA and each color of marshmallow will represent one of the four chemical bases. Kids will be able to see that only certain chemical bases pair with each other.

By mixing just flour, salt, and water, you’ll create a basic salt dough that’ll harden when baked. You can use this dough to make homemade dinosaur bones and teach kids about paleontology. You can use books or diagrams to learn how different dinosaur bones were shaped, and you can even bury the bones in a sandpit or something similar and then excavate them the way real paleontologists do.
Geode Kits – For any child who thinks rocks are boring – a kit where they can break open their own geode is a great way to change their mind. National Geographic is a great choice if this is the type of kit you are looking for. Their products include hand-picked geodes and come with safety goggles and a stand for your child to proudly display their treasures. A great choice for children aged around 6 years old and above, they’re sure to be more interested in Earth science after this experiment.
