Question:

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

2. Science FridayForecasting Avalanches
3. Investigation– What is the relationship between volume and density for objects of equal mass?  Complete calculating the densities and identifying the samples using the densities. Answer question 5. Tape the Activity handout as flip page to ISN p.59. Review data as a class. On ISN p.58, model relative size & arrangement of atoms/molecules in plastic & metal cylinders and write a Claim-Evidence-Reasoning (CER) regarding how the volume of cylinders of the same mass affects density.

Question:

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

1. Do Now– Copy down today’s homework assignment in your planner. 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 3 cm long. The mass of the cube is 54 g.
2. 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. Tape data table as flip page to p.57 and tape graph paper as flip page to p.56.
