Species Distribution & Change

Explain how environmental change (climate change, habitat loss, pollution) affects the distribution of species, including range shifts, local extinction, and invasive species

Lesson

Set out your lesson

Practise the bounded task in Species Distribution & Change; see exact limits before inferring broader coverage.

Before teaching

Use this short check, then start teaching.

Activity

Understands a species range as where it occurs; maps and cases below are labelled fictional/projected.

Policy

Exact directed source edges retained; earlier authorship is not learner attainment.

Printer, credit, and teaching notes

Exact directed source edges retained; earlier authorship is not learner attainment.

Materials

These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate

Sequence

Read readiness and decide on support without treating prerequisite authoring as learner readiness.
Open Show first and explain its model.
Use Guided Try with support and its separate adult key.
Close Show and guided keys before Try, unless this Try is explicitly supported.
Reflect on an actual attempt, including help used.

No Printer

Use the supplied screen cards; copying the exact task to paper is optional, not required.

Privacy

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view.

Before you open

Ask the learner one fact they learned and one question they still have.

Check understanding

Describes at least two ways environmental change can affect species distribution
Gives a real example of a species whose range has shifted due to climate change
Explains what an invasive species is and how environmental change can enable invasions
Discusses why some species are more vulnerable to environmental change than others

“If your child heard that wild plants in the UK are now flowering weeks earlier than they did 50 years ago, could they explain why that happens and what problems it might cause for the other animals that depend on those plants?”
