Misconceptions: Adaptation

Subject: Science | Year: 6

Class/Set: ____________ Date: ____________

Scope: Students frequently struggle with the mechanism of adaptation, often attributing 'intent' or 'choice' to animals rather than understanding it as a process of natural selection over time.

Misconception (What they think)	The Truth (The Correction)	Pedagogical Fix (Activity/Analogy)
"An individual animal decides to change to fit its environment."	Adaptation is a process that happens to populations over many generations, not to a single animal during its lifetime.	Model: Use the 'Peppered Moth' simulation. Show how the population's colour shifts over years, rather than a single moth changing its own wings.
"Adaptation happens because an animal 'needs' a certain trait to survive."	Traits appear through random genetic variation. Nature then 'selects' those best suited; the animal cannot conjure a trait through need.	Explain: Use the 'Lucky Dip' analogy. An animal is born with a set of 'tickets' (traits). If their ticket matches the environment, they survive. They cannot swap their ticket.
"The 'strongest' animal is always the one that survives (Survival of the Fittest)."	'Fitness' in science means the best fit for a specific environment. Sometimes being small, slow, or camouflaged is 'fitter' than being strong.	Compare: Present a Polar Bear and a Cactus. Ask: "Is the bear stronger?" Yes. "Would it survive in the desert?" No. Survival is about suitability, not just physical strength.
"If an animal exercises and gets strong, its babies will be born strong too."	Only genetic information is passed to offspring. Acquired characteristics (learned skills or physical changes during life) are not inherited.	Investigate: Ask the class: "If a parent loses a finger in an accident, will their baby be born missing a finger?" This helps distinguish between DNA and life events.
"Adaptation happens very quickly, like a Pokémon evolving."	Biological adaptation is a gradual process taking hundreds or thousands of years to become a fixed trait within a species.	Visualise: Use a 'Generation String'. Each bead represents a generation (20 years). Show how many beads are needed before a noticeable physical change occurs.

Task A: Adaptation Check for Understanding

Identify: Read the following statements. Label each one as Fact or Misconception.

1. A giraffe stretched its neck to reach high leaves, so its baby was born with a longer neck. __________
2. In a cold climate, animals with thicker fur are more likely to survive and have babies. __________
3. Birds decided to grow wings because they thought flying would be easier than walking. __________
4. Adaptation happens to a whole group of animals over a very long time. __________
5. A polar bear's fur turned white because it wanted to hide in the snow. __________

⚠ TEACHER’S GUIDANCE

💡 Pedagogical Pulse

• Address Oracy: Year 6 students often use the word "evolve" synonymously with "change". Encourage them to use "adapted over generations" to reinforce the temporal element of the National Curriculum.
• Tackle Teleology: Watch out for students using "so that" (e.g., "The bird grew a beak so that it could eat nuts"). Reframe this as "The birds with better-shaped beaks survived, therefore the trait was passed on."
• EYFS/KS1 Link: While this is a Year 6 resource, use concrete examples like household pets to explain inherited vs acquired traits to support lower-attaining students.

✅ Task A Answer Key

• Task A1 Answer: Misconception (Acquired traits are not inherited).
• Task A2 Answer: Fact (This describes the process of natural selection).
• Task A3 Answer: Misconception (Evolution is not a conscious choice).
• Task A4 Answer: Fact (Adaptation is a population-level process).
• Task A5 Answer: Misconception (Adaptation is a result of genetic variation, not desire).
