Density And Volume
Sixth graders explore the concept of density as a relationship of an object's mass to its volume. Densities of a variety of objects are compared and used to identify an unknown object.
Curated OER
Density
Learners find the mass, volume, and density of various objects. In this density measurement lesson plan, students observe how same-sized objects can have different masses, then use water displacement to find the density of each object...
