Why some animals live in groups

Ecosystems and food chains

CCSS NGSS.3-LS2-1England: KS2 Y4 Living things and their habitats

Objective and success criteria

Students will: Why some animals live in groups.

  • 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: Producers, consumers, predators and prey

Leads to: the next skill in this area.

Materials: Food web cards, Arrows to build chains, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).

Warm-up · 4 min

  • Quick retrieval from earlier learning (Producers, consumers, predators and prey). Students answer on mini whiteboards.
  • Show answers together and note who needs support in the main task.
  1. acacia leaves → giraffe → lion What is the acacia leaves in this food chain? (producer / tertiary consumer / secondary consumer / primary consumer) → producerPrompt: Start at the plant and count the arrows.
  2. seeds → mouse → owl Which animal is the predator of the mouse? (seeds / owl / mouse) → owlPrompt: A predator hunts and eats other animals; its prey is the animal it eats.
  3. Food chains: which statement is true? (Herbivores are predators. / Producers eat consumers. / A consumer gets its energy by eating other living things. / A food chain can start with a lion.) → A consumer gets its energy by eating other living things.Prompt: Producers make food; consumers eat.

Hook · 3 min

  • Show a food web and ask what would happen if one animal disappeared.
  • Share the objective: Why some animals live in groups. Read the success criteria together.

I do: model it · 7 min

  • Work through the example out loud, saying why you do each step, not just what you do.
  • Example: How does living in a group help here: wolves hunting as a pack?
  • Step 1: So the answer is: they can catch animals much bigger than one wolf
  • Answer: they can catch animals much bigger than one wolf
  • Pause after each step and ask a student to say what comes next.

We do: guided practice · 6 min

  • Do these together. Students try each step on whiteboards before you reveal it.
  • Use the hints as prompts rather than giving the answer.
  1. How does living in a group help here: emperor penguins huddling together? (they share warmth in freezing winds / adults protect the calves from lions / workers share jobs like collecting food and caring for young / it is hard for a predator to pick out one fish) → they share warmth in freezing windsPrompt: Think about food, safety, warmth and sharing work.
  2. Geese fly in a V shape and take turns at the front. How does this help? (Birds behind save energy, and sharing the front spreads the hard work. / It helps them see the ground. / It makes them fly slower. / It keeps them dry.) → Birds behind save energy, and sharing the front spreads the hard work.Prompt: Cyclists in a race ride close behind each other for the same reason.

You do: independent practice · 7 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 6 questions are on the student sheet below, with answers in the key.

Exit ticket · 3 min

  • Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
  1. What is one downside of living in a big group? (Food must be shared, and illnesses spread more easily. / Groups are always too cold. / Nobody ever helps anyone. / Predators can never find groups.) → Food must be shared, and illnesses spread more easily.Prompt: Think of a crowded classroom with one packet of biscuits.
  2. True or false? In a beehive, different bees do different jobs. (True / False) → TruePrompt: Think of the benefits and the costs.

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: Producers, consumers, predators and prey.
  • Use concrete materials: food web 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.
