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.
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.
The products listed here may contain small parts that are choking hazards for children! Toys can pose a hazard to babies and young children – they can choke, suffocate, or otherwise harm the child. Young children explore their world by putting things in their mouths, but children under three years of age do not have a well-developed coughing reflex and will choke easily on small items. All children, regardless of age, need close supervision with any toys to help prevent accidents from happening. Adult supervision is required at all times!
The best science experiments guide for kids ages 3-9. This is YOUR go-to resource for all things STEM and science all year round!  STEM stands for science, technology, engineering, and math. You can make STEM and science exciting, educational, and inexpensive for young kids. Fun and easy science for kids starts here! Don’t hesitate getting set up for science at home right away.
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.
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. 

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.
If you’ve ever wondered why someone can measure and pour ingredients into a bowl, mix them up, and then bake the batter in the oven to make a cake, you’ve thought about science. The process of mixing certain ingredients together and adding heat causes the ingredients to react and change. For example, baking powder or baking soda in a cake recipe will react with acidic or wet things in the batter to puff it up and make the cake light and fluffy. Scientists tested these reactions so many times that they learned what would happen every time. This is called experimentation, and you can do it, too.
