Physical changes in matter are the focus of this Grade 7 Science worksheet for the Matter and Chemical Change unit. Students examine observable signs of physical change and use evidence to explain what happens to matter without changing its chemical identity.

Build evidence-based understanding by working with examples such as phase changes and dissolving, where matter can change form or appearance without producing a new substance. Students also consider particle rearrangement, energy transfer, and mass evidence to connect observable changes with explanations at the particle level.

What Students Practice

The questions ask students to identify indicators of physical change, distinguish changes in form from changes in chemical identity, and explain why certain observations support a physical-change claim. The resource includes multiple-choice questions, true-or-false statements, short-answer responses, a reading passage, matching, a cloze passage, an essay, and a “Did You Know?” section.

Students specifically work with phase changes, dissolving, particle rearrangement, energy transfer, closed-system mass evidence, and the idea that a substance can change form while retaining its chemical identity.

Included Teacher Support

• ✅ Student Notes & Lesson Summary supplement for reinforcing key ideas
• ✅ Separate Teacher Guide with Learning Objectives and Teaching Tips
• ✅ Discussion Questions to support classroom conversation
• ✅ Common Mistakes section to help address likely misconceptions

Classroom Use

Use this physical changes worksheet for guided practice, independent classwork, review, or written evidence-building within a Grade 7 Matter and Chemical Change lesson. The varied response formats give students opportunities to recall concepts, interpret observations, explain their reasoning, and construct a written response.

The resource is identified with the Alberta framework and fits naturally into instruction focused on recognizing physical changes in matter and supporting scientific claims with observable evidence. The accompanying notes and teacher guide provide additional support for lesson preparation, discussion, and addressing common mistakes.
