Pure Substances and Mixtures Worksheets give Grade 6 science students structured practice with classifying substances, comparing mixture types, choosing separation methods, and supporting scientific claims with evidence. The review moves beyond simple definitions by asking students to apply what they know to familiar substances and multi-step separation situations.

What students practise

• Classifying substances as elements, compounds, or mixtures
• Distinguishing homogeneous and heterogeneous mixtures
• Identifying physical properties useful for separation
• Selecting methods such as filtration, magnetism, evaporation, and distillation
• Sequencing a procedure for separating components of a mixture
• Using claim, evidence, and reasoning to identify a pure substance

What is included

The resource includes a printable science worksheet with a complete answer-key version. Students work through classification tables, multiple-choice questions, short explanations, mixture-separation scenarios, procedural sequencing, and a final challenge involving iron filings, paper pieces, salt, and water.

Why the final challenge matters

Students must connect several ideas rather than answer isolated vocabulary questions. They identify distinguishing properties, choose an order of separation, explain why each method works, and use evidence about boiling and physical changes to support a claim. This makes the resource useful for checking whether students can apply pure substances and mixtures concepts in new situations.

Classroom use

Use this Grade 6 physical science review for independent practice, homework, a lesson wrap-up, small-group discussion, or science test preparation. The answer-key version also supports efficient checking and discussion of the reasoning behind each separation method and classification decision.

This worksheet focuses on the specific vocabulary and thinking students need for mixtures and solutions review, separating mixtures practice, and physical properties of matter instruction. :contentReference[oaicite:0]{index=0}
