Use these free science lessons, experiments, and activities to teach K-12 students about density.
Sometimes students wrongly think that an object's density is the same as its weight or its mass. Instead, density refers to an object's mass in a given volume. Two objects that have the same shape and size (volume) but have a different mass (like two same-sized balls with different weights) have different densities.
As a physical property of…
