What Is Matter?

What Is Matter?

What students learn

Students learn that matter is anything that has mass and takes up space. Start with Matter: See That Matter Is Everywhere and ask students to name objects around them that count as matter.

Why it matters

Matter is the starting point for studying materials, weather, cooking, water, and many everyday changes. Use States of Matter Song: Freeze, Flow, and Float as a quick memory hook for the forms matter can take.

Learn the idea

Matter can be tiny or huge, soft or hard, visible or invisible. Scientists describe matter by its properties, including shape, volume, and how its particles behave. Watch Matter: Notice How Particles Are Arranged before drawing a simple particle sketch.

Try it

Make three columns labeled solid, liquid, and gas. Have students sort classroom examples into each column. If they get stuck, replay States of Matter: Review Solid, Liquid, and Gas and let them revise their choices.

Parent guide

Ask your child to find five examples of matter at home. Include one object they can hold, one liquid, and one gas example such as air in a balloon. Keep the focus on the question, "Does it take up space?"
