Course

States and Changes of Matter

A Grade 2 science course about sorting matter into solids, liquids, and gases, noticing material properties, and describing simple changes in materials.

States and Changes of Matter

Course overview

This course helps Grade 2 students sort solids, liquids, and gases, notice simple properties of materials, and describe everyday changes they can observe.

What students will learn

  • Classify common objects and examples as solids, liquids, or gases.
  • Describe materials by properties like hard, soft, flexible, magnetic, conductor, and insulator.
  • Explain simple physical changes such as melting, freezing, bending, and evaporating.
  • Use science words to tell what changed and what stayed the same.

Lessons

Parent guide

Use small household examples such as a spoon, water, air in a balloon, a sponge, foil, ice, and paper. Ask children to say what they see, what changes, and what stays the same. Keep the talk concrete and let them sort or describe objects before giving the science term.

Completion

A student finishes when they can sort examples into solids, liquids, and gases, name a few material properties, and explain one simple change in a material.
