Teacher notes

- Project the whole-class version and poll answers before revealing the explanation.
- Pair the results with the Core Rules of Ecosystems worksheet for targeted written practice.
Common student mistakes
- Confusing core rules of ecosystems with a neighbouring idea in ecosystems.
- Reaching for a rule that belongs elsewhere in ecosystems.
