Try these fun and educational chemistry experiments at home with your kids! To make it extra special, keep a notebook with the results of each experiment, notes on what you’d try differently next time, and make a list of zany and logical inventions inspired by each experiment.
Polymers are really big molecules, made up of lots and lots of smaller molecules joined together. They can make materials bouncy like a rubber ball, stiff like a plastic toy, or stretchy like a piece of gum. One great way to play around with polymers is to make your own slime. In this experiment, we uplevel your standard green goo to a jet-black magnetic version that will magically move and dance without you even touching it!
What you see happening to the apples in this experiment is a chemical reaction, and in a chemical reaction, the molecules change! Vinegar reacts with baking soda, and one product of that reaction is carbon dioxide gas. This explains the fun fizzy bubbles that erupt from your apples!
