Compare Animal Life Cycles

Every animal has a life cycle. Some young animals resemble adults, while others change their bodies and behaviour dramatically.

Visual model

See how the ideas connect

Look · connect · explain
Start at the centre. Follow each line and explain how that idea belongs to Animal Growth and Change.

For students

Notice, predict, explain

Choose one part of the model. Predict how it connects to another part, then use the lesson evidence to explain your thinking.

For teachers

Pause for science talk

Show the model before the explanation. Ask “What do you notice?” and “What might change?” Then revisit student ideas after the worked example.

The big idea

Animals grow and change in different ways

A life cycle describes the repeating stages from the beginning of one generation to the beginning of the next.

Work it through

Frog and butterfly changes

  1. Step 1 A frog begins as an egg, becomes a tadpole, grows legs, and develops into an adult frog.
  2. Step 2 A butterfly begins as an egg, becomes a caterpillar, forms a chrysalis, and emerges as an adult.
  3. Step 3 Both cycles include eggs and adults, but the middle stages look and move differently.
  4. Step 4 Each stage has body parts and behaviours that help the animal survive in its environment.
