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.
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!
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. 

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.
Koala Crate is our line of science kits for kids ages 3-4. Introducing science and math to preschoolers may seem early, but in fact, it is crucial to building a strong foundation in STEM — science, technology, engineering, and math. Our crates introduce young learners to concepts like physics — through the science of rainbows — and biology — through learning about animals like reptiles and marine life.
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.
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.
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).
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.
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. 

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.
Have fun exploring science around your house and backyard. Take pictures of your experiment steps and make a science experiment notebook to record your findings. It’s safest to work with a parent or other adult when performing science experiments, though. Always get permission before you work like a scientist, and ask an adult to help you with the experiment steps.

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.

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.

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.

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. 

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 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.
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.
