from this Lab, they must know what density, mass, and volume are and know the comparison to teach other. Mass is the amount of matter in an object and volume is the amount of space that object is occupying. Density is the amount of mass in a given space, which is mathematically defined as mass divided by volume. Problem: How can you use density to determine the identity of materials? Objective: The purpose of this lab is to identify materials using density Hypothesis: In this lab I think we
