**Question:**

What is the relationship between mass and density for objects of equal volume?

**Learning Tasks:**

*Do Now*– Get out your science notebook and open to pages 56-57. Take out your data table and your graph paper. Work out the following density word problem on the colored paper strip: “*Calculate the density of a cube using the following information: Each side is 2 cm long. The mass of the cube is 16g.*“*Investigation*– What is the relationship between mass and density for objects of equal volume? Check data table and complete graph.*Model & Claim Evidence Reasoning (CER)*– On ISN p. 56, draw a model of the relative size and arrangement of atoms/molecules in metal, plastic, & wooden cubes based on your observations of the mass & density of the cubes. Also on ISN p.56, make a claim about the relationship between mass and density for objects of equal volume. Support your claim with evidence and reasoning.
