Home Science Experiments

Home science experiments are great for a rainy afternoon when the kids are bored. There are always a lot of things around the house that can be used for a science experiment.

One such experiment is to see why some cans of pop float while others do not. You have probably notice that when you open a cooler to grab a can of pop that some cans of pop are floating and some are at the bottom. This experiment will help you to understand why.

I recommend these printable science project plans for K-12 for hundreds of great project blueprints and this step-by-step guide for doing an award winning science fair project. Also be sure to check out these fun science kits as a fast, simple way to get started on your science experiment.

All you need for this experiment are several cans of different brands of unopened pop, several cans of different brands of unopened diet pop and a large aquarium or a sink. Fill the sink or aquarium about ¾ full of water and place all of the cans in the water, while making sure there are no air bubbles caught under the bottom of any of the cans. Which ones float and which ones don’t? Do the diet pops float or sink more often? Are there some brands of normal pop that float or do they all sink? The cans of soda have the exact same volume or size, so why do some float and some don’t? It all depends on what is dissolved in the soda. Regular pop has a lot of sugar to make it sweet, while diet pop has artificial sweeteners that affect their density. See what else you can find around the house to experiment with. There are many experiments involving eggs that you can do with materials from around the house.
