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. 

Hi Jean, I too just love doing science experiments with the kids. I ran a science party for my son’s 6th birthday and I’ve also run science art workshops during the holidays. If you send me your email address I’m happy to email you my notes and experiments. Here’s the link to my post about the party last year : http://sunnysidearthouse.blogspot.com.au/2013/07/mad-science-party.html
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.

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. 

Adults and kids will learn amazing new things about basic and acidic solutions with the Mind Blowing Science Kit. Whether erupting a color-changing volcano, creating a sunset in a test tube, 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. In addition to providing detailed instructions, the science guide makes it possible for those adults who might not have a background in science, or even any exposure to scientific experimentation, to knowledgably perform experiments successfully. The dynamic, colorful nature of the experiments included in this kit make it great for pleasing a crowd at family gatherings, parties, or science fairs.
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!
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.
Learn interesting science and technology facts by experimenting with different materials that react in surprising ways. You'll find a lot of experiments can be done using simple ingredients found around your house (with adult supervision of course). Basic materials can help you perform experiments that are simple, safe and perfect for kids. Enjoy our fun science experiments, make cool projects with easy ideas for children, show friends & family what you've discovered and most importantly, have fun!
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.
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.

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.

'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. 


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.

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.
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.

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.

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. 

This is one of the quick and easy and science experiments for kids to teach them about weather. It only takes about five minutes and a few materials to set up, but once you have it ready you and your kids can create your own miniature tornado whose vortex you can see and the strength of which you can change depending on how quickly you swirl the jar.
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. 

Making an electromagnet at home is fun and easy. Most magnets, like the ones on many refrigerators, cannot be turned off; they are called permanent magnets. This one can be and is therefor called an electromagnet. They run on electricity and are only magnetic when the electricity is flowing. The electricity flowing through the wire arranges the molecules in the nail so that they are attracted to certain metals.

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.

Call the emergency services straight away if anything goes wrong. However these are all well-tested and very safe for the ages provided by the manufacturers, so rest assured this is only a formality, but it is good to be safe and start young with proper preventative measures. After all, what you start now will set the example for what they grow up to be.
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.
3. Now remove about an inch of the plastic coating from both ends of the wire and attach the one wire to one end of a battery and the other wire to the other end of the battery. (It is best to tape the wires to the battery – be careful though, the wire could get very hot!) Now you can experiment by picking up paper clips and small non-aluminum objects.

Ah, slime. It’s the one thing that parents across the UK have been being pestered to make, so why not turn it into a science activity? For our concoction, we mixed shaving foam, PVA glue and a little bit of air freshener (fabric conditioner can work too!), to create a slime that you can swirl, stretch and crack, providing hours of fun. Try changing the quantities to see how the mixture changes, and ask the kids to explain the differences.
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.

In this quick and fun science experiment, kids will mix water, oil, food coloring, and antacid tablets to create their own (temporary) lava lamp. Oil and water don’t mix easily, and the antacid tablets will cause the oil to form little globules that are dyed by the food coloring. Just add the ingredients together and you’ll end up with a homemade lava lamp!
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!

My nieces are seven years old and into science. The experiments were easy and straightforward - easily read and done by the kids but adult supervision is probably a good idea. Mind blowing? Not so sure about that but very cool for the budding scientist. Perfect kit to start with. I think it's a cool way to encourage girls to love science and math. Boys will love it too - an exploding volcano! - so it really is great for the whole family. Younger kids could definitely participate with the aforementioned supervision. We LOVED it!

Scientific Explorer's Mind Blowing Science Kit makes it possible to create your very own science lab at home. This smartly designed science kit allows young scientists to perform several amazing science experiments that range from erupting a color-changing volcano to growing colorful, jiggly crystals. Young scientists will learn about basic principles behind the science including the difference between acids and bases, and how to use a test tube and pipette. Although designed for use by children ages four and older, adult supervision is needed for safety and to ensure that young scientists get the most out of the Mind Blowing Science Kit.
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 light refraction experiment takes only a few minutes to set up and uses basic materials, but it’s a great way to show kids how light travels. You’ll draw two arrows on a sticky note, stick it to the wall, then fill a clear water bottle with water. As you move the water bottle in front of the arrows, the arrows will appear to change the direction they’re pointing. This is because of the refraction that occurs when light passes through materials like water and plastic.

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.

Note that there are some ingredients not included that can be found in the house (like soda).
It happens to the Statue of Liberty and it happens to the change in your pocket! Create your own home lab with just a few household ingredients (this experiment will literally cost you just pennies). It’s also a chemical reaction with very non-toxic ingredients, so it’s safe and fascinating even for young kids. Click over to Buggy and Buddy to get the simple how-to.
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.
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.

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.
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.
What better way to teach your kids about science than with more than 70 experiments in a big bag? The Big Bag of Science contains scientific ingredients and a book of 30 pages filled with experiments like soda geysers, twisting tornadoes, growing jelly marbles, vanishing liquids, and more! The instructions are easy-to-follow and color-coded so your child will easily complete the experiment without any trouble. The book explains what’s going on in each experiment so they understand why and how things work.
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.
