Student lesson
- Adaptations suit a habitat.
- Structural: body features. Behavioural: actions.
- Natural selection acts over many generations.
- Individuals do not choose their adaptations.
Words to know
a feature or behaviour that helps survival
relating to body parts
relating to actions
survival and reproduction of the best-suited organisms
1. Discover: The desert beetle
A Namib desert beetle tips its body into the fog each morning. Water beads on its back and rolls to its mouth. “Its bumpy back and its fog-basking behaviour are adaptations,” says Ms Okoro.
Think: Why would a beetle without this ability struggle there?
2. Understand: Adaptation
Idea 1: Types
A structural adaptation is a body feature, such as a camel’s wide feet. A behavioural adaptation is an action, such as migration.
Idea 2: Fit
Each adaptation suits a habitat: thick fur in the Arctic, long roots in dry soil, bright colours that warn predators.
Idea 3: Natural selection
Individuals with helpful features survive and breed more, so those features become common in later generations. This natural selection is slow and works over many generations.
3. Worked examples
Example 1 (I show you): Classify
Adaptation.
- Fur.
- Migrate.
- Sort.
Answer: Structural or behavioural.
Example 2 (We do it together): Link
Habitat.
- Cold.
- Dry.
- Dark.
Answer: Match feature to habitat.
Example 3 (You try): Explain
Selection.
Show the steps and answer
- Survive.
- Breed.
- Pass on.
Answer: Helpful features spread.
Did you know?
Darwin and Wallace independently proposed natural selection in the 1800s.
Why this matters
Adaptation explains why living things suit where they live.
4. Explore: Beak challenge
Use tweezers, spoons and clothes pegs as beaks to pick up seeds, rice and small pasta and see which tool suits each food.
- Choose a tool.
- Try each food.
- Time it.
- Compare.
Think about it: what did you notice?
What did you notice? Each tool suited one food best.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Define adaptation | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O2 Give structural and behavioural examples | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O3 Link adaptation to habitat | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Animals choose to adapt.” No.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain adaptations.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child explores adaptations. You do not need to be an expert to help.
- Watch birds feed.
- Ask “Why that beak?”
- Wash hands.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: define adaptation; give structural and behavioural examples; link adaptation to habitat; explain natural selection simply.
Prerequisite knowledge. Grade 5 ideas: living things, habitats, food chains and adaptations.
Materials. Tweezers, spoons, pegs, rice, seeds, trays. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Prepare trays.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Show two beaks and ask, “What food does each suit?”
Explanation (10 min). Teach adaptations.
Guided activity (10 min). Learners test beaks.
Independent activity (10 min). Learners explain.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How does the feature help? What habitat?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Animals choose to adapt.” No.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Explain adaptations. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
