Density is a measure of mass per volume. Items that are more dense have more mass per unit of volume than items that are less dense.
For example, one cup of freshwater has less mass than one cup of salt water. This is because the salt adds mass to the water. Fresh water will float on top of salt water because fresh water has less mass than the salt water. But you can float other things in salt water too! A common science demonstration is seeing how an egg floats in salt water compared to how it floats in fresh water. You may have even experienced this yourself - by floating in a mineral spa!
This demonstration uses fresh and salt water to explore density by observing how colors do or do not combine with each other! Check it out!
