Teaching Density Density is mass divided by volume. d=m/V or ρ=m/V But what does that mean? The simple answer is how heavy something is for its size. If something seems very heavy for its size (like a ...

If you’re looking for a fun way to explore the physical properties of density with your elementary-aged kids, this experiment is for you!

Researchers have created a never-before-seen form of ice with a disorganized structure and a density almost exactly that of liquid water.
