Insect hotels can be as simple (just a few sticks wrapped in a bundle) or as elaborate as you’d like, and they’re a great way for kids to get creative making the hotel and then get rewarded by seeing who has moved into the home they built. After creating a hotel with hiding places for bugs, place it outside (near a garden is often a good spot), wait a few days, then check it to see who has occupied the “rooms.” You can also use a bug ID book or app to try and identify the visitors.
There are a lot of science kits for kids out there, so it can be difficult to work out which brands are the best. Some of our favorites for realistic experiments include 4M and National Geographic. For younger kids, the Kids First brand has a lot of good value kits to choose from. The brand Sick Tricks is also a great choice for kids looking to impress their friends or parents with new tricks and experiments. For robotic science kits, Cozmo and LEGO are great options.
This experiment is a great way for young kids to learn about static electricity, and it’s more fun and visual than just having them rub balloons against their heads. First you’ll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly’s wings. The wings will move towards the balloon due to static electricity, and it’ll look like the butterfly is flying.
There are many different types of children’s scientific equipment and learning activities and here we will review some of the best and feature the highlights and reasons to choose one over the other. Some like to use home-made diy type science activities and others prefer the box sets that come all prepared. Both are fantastic and we applaud the parent willing to spend the time going through kitchen worktops and cupboards to make learning enjoyable for their kids.

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.


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!
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. Check out more of Art and Soul's gorgeous eggs over at their blog!

This science kit is perfect for my son. I got it for his 6th birthday and we've been having so much fun doing the experiments. It came with nearly all of the supplies except for simple things you have in your home like baking flour and water. Other kits I've bought have required so many other items which we didn't have, this one is so easy to use. He loves using the test tubes, the dropper, measuring out the components with the scoopers. He said it makes him feel like a real scientist. His 4 year old sister likes doing experiments too. This is the best kit to buy for a young child. So easy for them AND for you.
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.
Adults and kids will learn amazing new things about basic and acidic solutions with the Mind-Blowing Science Kit. Whether erupting an under-water volcano or growing colorful, jiggly crystals, this science kit mixes learning with experimentation in a fun and colorful way for a wide range of ages. Each of the hands-on activities in the science guide is intended to be performed by a young scientist under adult supervision, although these activities can be adjusted to accommodate a range of ages and capabilities while still maintaining the educational excitement of the original experiments.

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.
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. 

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.

Education and science go hand-in-hand and one without the other is a sad time for any child indeed. There are loads of ways to get your children into science and the sooner the better. One way is to have fun with scientific experiments that use hands-on learning techniques. The hands-on approach is ideally what young scientists want to do and the less theory the better, especially when they are so young.
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.
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.
By creating an articulated hand model, you can teach kids about bones, joints, and how our hands are able to move in many ways and accomplish so many different tasks. After creating a hand out of thin foam, kids will cut straws to represent the different bones in the hand and glue them to the fingers of the hand models. You’ll then thread yarn (which represents tendons) through the straws, stabilize the model with a chopstick or other small stick, and end up with a hand model that moves and bends the way actual human hands do.
Fire is fun. Colored fire is even better. These additives are safe. They won't, in general, produce a smoke that is any better or worse for you than normal wood smoke. Depending on what you add, the ashes will have a different elemental composition from a normal wood fire, but if you're burning trash or printed material, you have a similar end result. In my opinion, this is suitable for a home fire or campfire, plus most chemicals are found around the house (even of non-chemists).

You’ve probably seen the label that says “fortified with iron” on your cereal box, but how much iron is actually in your cereal? Is there enough to cause a magnetic reaction? This super easy experiment doesn’t require too many fancy ingredients (cereal + magnet) which means you and the kiddos can try it right away. The results may surprise you! Get the how-to at Rookie Parenting and get started!

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.
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.
It’s important to get kids involved in science early so they understand the world around them. These science kits focus on critical thinking skills that will give your kid’s hands-on experience to build their curiosity and interest. Help your children discover the fun in learning by checking out these kits that teach them how to conduct their own experiments through the many different fields of science.
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!

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.
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.
As you wonder and ask questions, experiments will let you watch chemical reactions as they happen. Even something as simple as writing a secret message on the bathroom mirror with a cotton swab and dish detergent can teach you about science. When the bathroom fills with warm steam from a shower, your message will appear like magic on the mirror. It’s not really magic, though. The dish detergent on the mirror is preventing water molecules in the steam from sticking together, so you can see the letters you wrote earlier.
Scientific Explorer's Mind Blowing Science Kit includes almost everything you need to set up exciting, colorful experiments with your young scientist. Included in this dynamic kit are the following components: red cabbage juice powder, citric acid, color tablets, polyacrylamide crystals, a pipette, small and medium scoops, and three plastic cups. Only basic supplies are required but not included, such as water, towels, a plate or tray to catch spills, and a stirring spoon. Although none of the experiments included in this kit are especially messy, each one should be done on a flat surface that can be easily wiped clean in case of spills.
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.
Have you ever gone into a cave and seen huge stalactites hanging from the top of the cave? Stalactites are formed by dripping water. The water is filled with particles which slowly accumulate and harden over the years, forming stalactites. You can recreate that process with this stalactite experiment. By mixing a baking soda solution, dipping a piece of wool yarn in the jar and running it to another jar, you’ll be able to observe baking soda particles forming and hardening along the yarn, similar to how stalactites grow.
While The Big Bag of Science included some fun chemistry experiments, My First Mind Blowing Science Kit focuses solely on chemistry and chemical reactions. Want to witness a sunset in a test tube? What about a color-changing (or even underwater) volcano? This kit includes ingredients your child will need to conduct these colorful experiments over and over again—or at least until the powders, polymers, and oils run out.
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.

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.

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.
The latest science kits come kitted with all sorts of lab equipment like utensils, beakers, test tubes, filter funnels, safety glasses and a range of devices to make learning and experimenting exciting. One of my favorite ones is how to grow and watching how a caterpillar turns into a butterfly, which is very beautiful. With so many to choose from, one is definitely going to fit your child’s needs.
This experiment is a great way for young kids to learn about static electricity, and it’s more fun and visual than just having them rub balloons against their heads. First you’ll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly’s wings. The wings will move towards the balloon due to static electricity, and it’ll look like the butterfly is flying.

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?

'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. 
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.
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.

Wonderful ideas! As a former science teacher, science department chair and system-wide science supervisor,; I salute you! It is mothers like you who keep the spark of investigation going in the eyes of our children. I love, love love hands-on science! You are training the scientists of tomorrow…or maybe the artists…doesn’t matter, we need both! Suggestion: let them see how many drops of water they can get on a penny. All you need is a penny, a medicine dropper and water. Oh, and a very steady hand and table that doesn’t shake. Then fill a jar with water (almost to the top) and predict how many pennies they can put in until the water overflows. Good lesson in surface tension and cohesion. You will need a steady hand, sturdy surface and a lot of pennies! I have some others, but no enough space.
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.
Adults and kids will learn amazing new things about basic and acidic solutions with the Mind-Blowing Science Kit.

This Rainbow Skittles science experiment can be done in seconds, making it a great way to try science at home even with the most easily distracted of toddler-sized assistant. All you’ll need to do is arrange Skittles in a circle on a plate and fill the middle with warm water. Then sit back and watch as the colours drain and mix with the water, creating a cool rainbow pattern in front of your eyes. Plus, any bonus Skittles = a tasty treat for you.
Rock kits – This area tends to include those already covered such as geodes and geology kits, as well as crystal growing sets. They might also include rock collections, which your child can identify then how off their knowledge. Another great product coming under this category is the rock tumbler. Using this special machine, kids can turn ordinary rocks into shiny gemstones. Kids can then get creative and turn their new rocks into keychains, jewellery, or anything they fancy. A great way to combine science and art.
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.
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). 

The good news is that your white lab coat doesn’t have to sit in the closet collecting dust. There are a lot of fun, simple, and hands-on science projects families can do together to learn and understand some of the basic principals of the natural world. And they’re not just for kids: even moms and dads will get a kick out of these 10 family-friendly science experiments!
Children aged 9+ start to want more detailed experiments and activities, which shows they are ready to begin real-science. Whether they have interests in physics, chemistry or robotics there is always something to get them started on their way. Some tops are harder than others and make sure you read all the features and facts so that you find the ideal gift for your child.

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.
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.
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.
This mechanical weathering experiment teaches kids why and how rocks break down or erode. Take two pieces of clay, form them into balls, and wrap them in plastic wrap. Then, leave one out while placing the other in the freezer overnight. The next day, unwrap and compare them. You can repeat freezing the one piece of clay every night for several days to see how much more cracked and weathered it gets than the piece of clay that wasn’t frozen. It may even begin to crumble. This weathering also happens to rocks when they are subjected to extreme temperatures, and it’s one of the causes of erosion.
