The Standard

matter has mass and takes up space

Virginia Standards of Learning for Science

Teacher's field guide

What Students Need to Do: Students identify solids, liquids, and gases as matter. They use a balance, container, or syringe to gather evidence that each has mass and fills space.
What Mastery Looks Like: A student can classify a rock, water, and air as matter and give evidence for each. The student chooses a suitable test using a balance or container.
Common Misconceptions: Students may think only solid objects are matter, or that air is nothing. They may confuse mass with size and assume larger objects always have more mass.
How to Assess It: Show a rock, a cup of water, and air trapped in a syringe. Ask, “Are all three matter? Name one observation or test that supports your answer.”

Lesson moves

Weigh a flat ball before and after inflation, then use a capped syringe to show that trapped air resists being squeezed.
Ask students to answer, “A classmate says air is nothing. What evidence from a balloon or syringe proves otherwise?”
Play Matter Evidence Match by pairing solid, liquid, and gas picture cards with balance, syringe, or container test cards.
Read a grocery package’s net weight and container size, then explain what each tells a shopper about the matter inside.
