Variation in Species
Explain variation within and between species, distinguishing between continuous variation (e.g. height) and discontinuous variation (e.g. blood group), and between genetic and environmental causes

Teaching Table
Set out your lesson
Practise the bounded task in Variation in Species; see exact limits before inferring broader coverage.
Read frequency counts; discuss differences without ranking people.
Exact directed source edges retained; earlier authorship is not learner attainment.
These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate
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.
Use the supplied screen cards; copying the exact task to paper is optional, not required.
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. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
No causal experiment, genetic diagnosis or personal measurements; human examples remain explanatory only.
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.

Check understanding
- Gives examples of continuous and discontinuous variation in humans
- Distinguishes between genetic causes of variation (inherited differences) and environmental causes (diet, sunlight, etc.)
- Explains why sexual reproduction produces greater variation than asexual reproduction
- Draws or interprets a frequency graph showing continuous variation
“If your child looked around a classroom and noticed that everyone has slightly different heights, hair colours, and eye colours, could they explain why these differences exist — and which ones are inherited, which are down to the environment, and which are both?”
