What This Standard Means
What Students Need to Do
- Students measure mass with a balance and volume with a graduated cylinder or dimensions. They calculate density by dividing mass by volume and compare materials using correct units.
What Mastery Looks Like
- Given an unknown solid or liquid, students collect reliable measurements and calculate its density. They can explain why sample size changes mass and volume but not density.
Common Misconceptions
- Students may confuse mass with volume or divide volume by mass. They may think a larger sample is always denser. Some misread graduated cylinders or forget to subtract displaced water when finding irregular volume.
How to Assess It
- Exit ticket: A block has a mass of 54 g and a volume of 20 cm³. Calculate its density, show your setup, and include units.

Ways to Teach It
Set out aluminum, wood, plastic, and clay samples for students to measure, calculate density, and rank from least to greatest.
Ask students to write: Why do two aluminum pieces with different masses have the same density?
Run a density card match with separate mass, volume, density, and material cards that teams combine into correct sets.
Have students identify an unknown metal part by measuring its density and matching the result to a reference table.
