Identify states of matter
Free printable Grade 6 science worksheet for "Identify states of matter" — practice matter and particles. No-prep, print or assign online.
Students in middle school identify the defining characteristics of each state of matter — solid, liquid, and gas — at the particle level in this hard-level Physical Science worksheet on matter and particles. Teachers can use it to push students beyond surface-level observation toward a molecular explanation of why matter behaves differently in each state. It belongs in a Matter and Particles unit and prepares students for more advanced topics in chemistry and physics.
Learning objectives
- Identify the states of matter and describe their properties at the particle level
- Explain how particle arrangement and motion differ among solids, liquids, and gases
