10 Quick & Easy Science Experiments for Kids

Did you know there are a ton of fun, simple science experiments you can do at home using everyday household items like marbles, paper, pennies, and apples? These easy experiments are a great way to explore simple scientific concepts like heat expansion, tensile strength, sound waves, chemical reactions, and cloud formation from the comfort of your kitchen table! Guess what will happen, observe the result, then try to explain why what you observed does or doesn't line up with your guess. Lab coats are optional, but encouraged!

    Crackled Marbles

    (Ages 5-10)

    This experiment uses marbles to demonstrate the effect of a thermal shock on glass. Heat a group of marbles in the oven, then transfer them to the freezer, observe, and then try to explain the dramatic changes that take place!

  • Visual aid of how to complete Dancing Sprinkles

    Ever wondered if you can see sound? Well, in this experiment, you’ll use a Ziploc® brand sandwich bag to turn music into motion. It works because sound is a wave: a vibration that travels through the air (or another material) like a wave travels through water. Normally, we only hear these vibrations, and we can't see them. But by using the vibrations to make sprinkles dance, you’ll be able to see sound waves!

  • Visual aid of how to complete Magic Cloud in a Bottle

    Whether they're bringing down rain or snow, making a beautiful sunset, or letting our minds run wild with imaginary shapes - clouds are pretty awesome. Did you know that you can create your own cloud in a bottle with just a few easy steps? Follow along with this simple DIY (or watch the video tutorial) to learn about how clouds form, while creating you own cloud in a bottle!

  • Visual aid of how to complete Apple Oxidation Experiment

    Have you ever noticed that if you slice an apple in the morning, it turns brown by lunch? This is actually a chemical reaction at work! In this experiment, you’ll learn more about how the oxygen in the air around us causes this reaction (also known as oxidation). With a little help from Ziploc® brand bags, test different liquids to see if you can figure out a way to keep apples fresh from morning to noon.

  • Visual aid of how to complete How Strong is Paperr

    Can a flat piece of paper hold the weight of a hardcover book without breaking? What about ten books? Or Twenty? What if you roll the paper into a column? How does changing the structure of the paper effect its tensile strength? Explore basic principles of engineering with this simple household experiment.

  • Visual aid of how to complete Electromagnet

    (Ages 9-16)

    Unlike the magnets that are used on refrigerators, electromagnets are magnets that can be turned on and off depending on the flow of electricity. The electricity that flows through the wire allows the molecules in the nail to attract certain things. Give this experiment a try, and see how many paper clips you can pick up with your electromagnet!

  • Visual aid of how to complete Milk Swirl Experiment

    My kids can't get enough of this super-simple science experiment. I love that it's easy and safe enough for kids of all ages, and uses only ingredients I already have in the kitchen. The end result is an explosion of colors, and it almost looks like magic! Watch our video to see us make the colorful experiment from start to swirling color.

  • Visual aid of how to complete Lava Lamp Science Project

    Have you ever seen a lava lamp? All of the colorful wax that rises and falls, bobbing around--it's mesmerizing! You've probably wondered how to make one. This is an easy science experiment that you can do at home to create your very own homemade lava lamp. And it only takes a few common household ingredients!

  • Visual aid of how to complete Compound Pulley
    Compound Pulley

    (Ages 9-16)

    This setup is a compound pulley, which combine both fixed and moveable pulleys to increase the mechanical advantage.

    In a pulley system, a wheel's job is to let the rope move freely. Here, this set up works with no wheels. The broom can act as the wheel since it's low-friction enough that the rope can easily move over it.

  • Visual aid of how to complete Bright as a Penny

    What's the best way to clean a penny? What chemicals do the best cleaners have in common? The kids and I aimed to find out...

Get inspired!
