Animals and habitats

Objective and success criteria
Students will: When an environment changes: move, adjust or die out.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Adaptations to habitats
Leads to: the next skill in this area.
Materials: Animal picture cards, Habitat maps, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval from earlier learning (Adaptations to habitats). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- An Arctic fox's coat turns white in winter. How does this help? (It scares other foxes. / It stays cooler. / It can swim faster. / It is camouflaged against the snow.) → It is camouflaged against the snow.Prompt: What colour is the ground in winter in the Arctic?
- Adaptations: which statement is true? (Fish have gills to take oxygen from water. / A giraffe's neck grew longer because its parents stretched. / Every animal can live in every habitat. / Animals choose to grow adaptations when they need them.) → Fish have gills to take oxygen from water.Prompt: Adaptations take many generations to appear.
- Adaptations: which statement is NOT true? (Animals choose to grow adaptations when they need them. / Fish have gills to take oxygen from water. / Some animals use camouflage to hide from predators. / Cactus spines help reduce water loss and protect it from animals.) → Animals choose to grow adaptations when they need them.Prompt: Can an animal decide to change its body for its babies?
Hook · 6 min
- Show a picture of an unusual animal and ask where it might live and how it survives there.
- Share the objective: When an environment changes: move, adjust or die out. Read the success criteria together.
I do: model it · 12 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: What is a likely effect of this change: a pond dries up in a drought?
- Step 1: So the answer is: frogs and fish that cannot leave may die
- Answer: frogs and fish that cannot leave may die
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 12 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- What is a likely effect of this change: Arctic sea ice melts earlier each spring? (flowers may bloom before the insects that feed on them hatch / animal homes are split and crossing becomes dangerous / polar bears have less time to hunt seals on the ice / frogs and fish that cannot leave may die) → polar bears have less time to hunt seals on the icePrompt: Which living things depend on what was lost or changed?
- A wetland is drained to build houses. What can the ducks living there do? (grow gills / live inside the new houses / fly to another wetland if one is nearby / turn into land animals overnight) → fly to another wetland if one is nearbyPrompt: Birds can travel. Can every animal?
You do: independent practice · 17 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 7 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- What is a likely effect of this change: Arctic sea ice melts earlier each spring? (woodland birds lose nest sites and many move away / flowers may bloom before the insects that feed on them hatch / animal homes are split and crossing becomes dangerous / polar bears have less time to hunt seals on the ice) → polar bears have less time to hunt seals on the icePrompt: Which living things depend on what was lost or changed?
- True or false? Changes to habitats are always caused by people. (True / False) → FalsePrompt: Think about moving, surviving and dying out.
Watch out for
- Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
- Remembering facts without the reason: ask "why?" and "what is the evidence?"
Support and stretch
Support
- Review first: Adaptations to habitats.
- Use concrete materials: animal picture cards.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
