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.
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.
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.
Find out how plants “drink” water with some food coloring. Use carnations, roses, or stalks of celery submerged in the colored water and watch the liquid slowly seep through the plant’s “veins” and towards the leaves. Keep an eye out -- you could have a very colorful bouquet just after the first day. Get the rundown by Dad’s Book of Awesome Science Experiments over here.
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!

Science is a wonderful thing for kids! There is so much to learn and discover right around us. Many science concepts start in the kitchen with simple materials you already have on hand. Fill a plastic tote with easy to find supplies and you will have a homemade kids science kit filled with learning opportunities that are sure to keep them busy all year long!
It takes a few hours to see the results of this leaf experiment, but it couldn’t be easier to set up, and kids will love to see a leaf actually “breathing.” Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you’ll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.
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.
Disgusting Kits – These kits are great for young boys especially, who love everything gross! They will love to create horrible slime and sludge to gross out their friends, and parents! They tend to feature things like brains and snot – sure to be popular with little ones! Parents will love that their kids can explore disgusting substances in a fun, safe and educational way.
Chemistry Kits – Perhaps the most classic of the science kit options, these are great for kids who are interested in learning about how things work. There is a huge range of kits in this bracket, ranging in features and suitability. There is a chemistry kit for just about any child, and with a bit of research it’s easy to find one to suit your child’s age and ability.
