Chemical reactions worksheets for Grade 6 Science focus on using evidence to decide whether new substances formed during a reaction. Students examine qualitative observations and quantitative measurements to identify evidence of chemical change within the context of Matter and Its Interactions and NGSS.

Build Evidence-Based Chemical Reaction Reasoning

Students identify visible indicators such as color change, gas production, and precipitate formation, then use mass and temperature changes to interpret what happened before and after a reaction. The resource moves beyond simply recognizing signs of change by asking students to connect observations and measurements with the formation of new chemical species.

What Students Practise

• Recognize qualitative evidence that may indicate a chemical reaction.
• Interpret pre-reaction and post-reaction mass and temperature measurements.
• Use evidence to determine whether new substances were formed.
• Explain conclusions about chemical reactions using observations and data.

The worksheet includes multiple-choice questions, true-or-false statements, short-answer responses, a dialogue, matching, a cloze passage, a labeled diagram, a reading passage, and an essay. This variety gives students opportunities to recognize evidence, interpret information, communicate reasoning, and apply the central concepts in different ways.

What You Receive

• Worksheet covering evidence of chemical reactions and interpretation of reaction data
• Separate Teacher Guide PDF with Learning Objectives, Teaching Tips, Discussion Questions, and Common Mistakes

Practical Classroom Use

Use this Grade 6 chemical reactions activity for focused classroom practice, independent work, review, or assessment of students' ability to interpret evidence of chemical change. The teacher guide supports instruction before or alongside the worksheet, while its discussion questions and common-mistake notes can help guide classroom conversations about how observations and measurements support scientific conclusions.

For teachers covering Matter and Its Interactions, this resource provides targeted practice with chemical reaction evidence rather than relying on memorization alone. Students are asked to interpret what the evidence means and decide whether a reaction produced new substances, making it useful for reinforcing scientific reasoning around chemical changes.
