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.
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 My First Mind Blowing Science Kit is your junior chemist’s introduction to the world of scientific exploration. Learn the basics of science from chemical reactions to the use of science tools. With mind blowing experiments such as creating a sunset in a test tube and making a color-changing volcano, children will love learning fascinating facts about their natural world and this kit will keep them engrossed with interactive experiments. Includes Red cabbage powder, citric acid, baking soda, 3 color tablets, crosslinked polyacrylate copolymer, vegetable oil, corn starch, 2 cotton swabs, 3 test tubes with stand, 3 plastic cups, pipette, 2 sticks, 2 measuring scoops and activity guide. Recommended for children 6 years of age and older with adult supervision.

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.

'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.

Have you noticed that science seems to be a hot topic recently? Wondering how you can help at home? As busy moms of three kids and former elementary school teachers we’ve shared over 30 science experiments for you at The Educators’ Spin On It.  Our biggest tip is to simply allow time for it.  Encourage your child to use those “wh” questions to explore their world through a scientific view…What, Why, How, Where, When. Take a peek below at our science activities and let us know which one you want to do first!
If you do this sidewalk constellation craft, you’ll be able to see the Big Dipper and Orion’s Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.
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.
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.
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!

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. 

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.
Ever got an electric shock off something? Demonstrate the science behind the shocks with this jumping frogs experiment. With just a balloon, some sugar paper and a woolly jumper, you’ll have frogs leaping in no time demonstrating the power of static electricity. It doesn’t have to be frogs either, let your imagination run wild to create some other jumping stars of this easy science experiment!
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.
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.
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.
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.
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.

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.
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.

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 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.

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.
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.

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.
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.

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.

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 kitchen can be an ideal place for performing science experiments, with an adult’s help. For instance, with a few stalks of celery and some food coloring, you can watch capillary action happen almost before your eyes. Capillary action describes what happens as plants move water up from their roots to their leaves. Get four stalks of celery and cut off the bottoms so each stalk is 10 inches long. You’ll also need four identical cups, each filled with a half-cup of cool water. Decide what color you want to make the water, and then add the same number of drops of food coloring to each cup of water. Stir the water well with a spoon. Place one stalk of celery into each cup. After two hours, remove one stalk and label this one “two hours.” After four hours, remove another stalk and label it the same way. Do the same with the next stalk at six hours and the final stalk at eight hours. After you finish, compare the celery stalks to see how each one changed color, depending on how long it was in the colored water.
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.
You’ve probably tried a salt crystal growing kit at some point in your life (5th grade Science Fair perhaps?) but Schooling a Monkey takes the idea to a new level with these Salt Crystal Feathers. This awe-inspiring project is deceptively simple and inexpensive to achieve, and requires just a wee bit of patience to see the results—kids will love checking in on the progress. Visit Schooling a Monkey now to get started.
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.
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.
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.
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!
