Adaptive teaching
Pupils needing extra support
Should use the Activity: Modelling natural selection: support version that provides prompts for summarising results and a writing frame for completing an evaluation.
Pupils working at greater depth
Could use the additional row in the results table to test another model beak (e.g. alternative tweezers, chopsticks or tongs) and compare further data; should consider other factors that may affect which bird will survive when discussing or writing a conclusion (including other animals competing for the same food or a predator that hunts the animal as its prey); could design a beak shape that is even better adapted to the rice-shaped food.

Knowledge outcomes
- I can describe variation in a given population, such as the different shaped beaks of finches.
- I can explain how variation may affect survival within a population, such as some beaks being better adapted to pick up food than others.
- I can recall that natural selection is the process where living things better adapted to their habitat are more likely to survive, whereas those less well adapted are more likely to die.

Vocabulary definitions
-
competition
When an organism is trying to be more successful at something, such as escaping predators or finding food.
-
natural selection
