Rearrangement of atoms in reactions in Year 7 Science
Start here
Focus on how atoms rearrange in chemical reactions. Start with “Apply the Law of Conservation of Mass to Equations”, then explain the idea in your own words.
Year 7 learners practise how atoms rearrange in chemical reactions.
The activities include Apply the Law of Conservation of Mass to Equations, Understand How to Represent Atoms in Chemical Reactions. The checked support below includes video, lesson, teaching, worksheet. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
Activities covered
- Apply the Law of Conservation of Mass to Equations
- Understand How to Represent Atoms in Chemical Reactions
