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. 

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.
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.
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.
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.

a tube, yeast, sugar and warm water, a deflated balloon over the top shake the yeast “farts” which causes the balloon to inflate. I did this at a sleep over with boys 7 to 9 they loved it. you can use an empty water bottle, 1 packet of active yeast, 1/4 cup warm water 1 tsp sugar, large balloon, ruler to measure. measure in 5 min increments. The water wakes the sleeping yeast up. they wake up hungry, you feed them the sugar and their waste/farts are gas that fill the balloon. As they eat the more gas they produce thus filling the balloon. It doesn’t blow all the way up, but it is cool. – Jackie


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!

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.
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.
When a substance passes directly from a solid phase to a gas phase without ever becoming a liquid, it sublimates. Add a little dry ice to bubble solution and the contents of an activated glow stick and get ready to rock the glow-in-the-dark scene in your neighborhood. Owlcation whipped up this awesome experiment to create glowing bubbles, and The Maker Mom thought to add dry ice to the same experiment here. The bubbles are out of this world—they glow and rise from the smoke. Naturally, we recommend an adult to handle the dry ice (skin contact can burn) and supervise this experiment.
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.
Invisible inks either react with another chemical to become visible or else weaken the structure of the paper so the message appears if you hold it over a heat source. But we're not talking about fire here. The heat of a normal light bulb is all that's required to darken the lettering. This baking soda recipe is nice because if you don't want to use a light bulb to reveal the message, you can just swab the paper with grape juice instead.
We have categorized by age to make things really easy when deciding which type of experiment kit to go for and start experimenting with. There is everything from geology rock experiments, ocean discovery kits, volcano boxed experiments, butterfly and insect garden kits, robotics activities and kits, human biology box sets and chemistry sets that bring the obscure into light making learning loads of fun and super exciting for everyone involved.  These mentioned are only in the 3 years old and over a section, but we also have a 6 years old and above, because we understand the capabilities of children. The section for 8 years old and above come under one section to help make a clear distinction.
Insert a little plant science into the mix by re-growing food from scraps. Think onions, potatoes, and lettuces for this one (psst… green onions are a super easy, fast option). Get the low down on all that recycled goodness at Mrs. Happy Homemaker. Since plants need water and sunlight to grow, exposing scrap roots to that winning combo helps them recharge.
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.
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.
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 solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)
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.
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!
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.

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.

This kit also teaches your kids about the influential scientists who paved the way in the field, such as Francis Crick, James Watson, and Gregor Mendel. From genes, heredity, traits, and inheritance, to reproduction, cellular components, DNA sequencing, and genetic engineering—this kit will teach it all in a fun and educational way that your kids are sure to love.
Are you looking for cool science experiments for kids at home or for class? We’ve got you covered! We’ve compiled a list of 37 of the best science experiments for kids that cover areas of science ranging from outer space to dinosaurs to chemical reactions. By doing these easy science experiments, kids will make their own blubber and see how polar bears stay warm, make a rain cloud in a jar to observe how weather changes, create a potato battery that’ll really power a lightbulb, and more.
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.
Any one of these simple science experiments for kids can get children learning and excited about science. You can choose a science experiment based on your child’s specific interest or what they’re currently learning about, or you can do an experiment on an entirely new topic to expand their learning and teach them about a new area of science. From easy science experiments for kids to the more challenging ones, these will all help kids have fun and learn more about science.

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 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.
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. 

When these nails and copper wires collide, heat is generated (psst ... heat is a result of expended energy, so you can explain to your little runner why he feels warmer after a race around the house). But with some potato magic, the properties of the nail and copper stay separated, allowing the heat to become the electric energy needed to power up your devices. Build your own potato battery with this tutorial from PBS Kids.
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.
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.
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!
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.
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 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.
