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!
Dancing Sprinkles(Ages 9-11)
Ever wondered if you can see sound? Well, in this experiment, you’ll turn music into motion.

Apple Oxidation Experiment(Ages 3-4)
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 bags, test different liquids to see if you can figure out a way to keep apples fresh from morning to noon.

How Strong is Paperr(Ages 3-8)
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.
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!
Milk Swirl Experiment(Ages 3-11)
See how a drop of soap can create an explosion of color with this easy experiment!

Fizzy Lava Lamp(Ages 5-16)
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!

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.
Bright as a Penny(Ages 3-8)
What's the best way to clean a penny? What chemicals do the best cleaners have in common? Give this experiment a try and find out.
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!
