Life Cycle Lab
A living thing passes through stages in a particular order, and reproduction links the adult stage to a new generation so the pattern repeats as a life cycle.

What your child will figure out
- Order the observable stages of butterfly, frog, flowering plant, and ladybird life cycles.
- Use visible changes between neighbouring stages as evidence for what comes next.
- Explain why a life cycle repeats across generations instead of ending at adulthood.
- Transfer stage-ordering to generated organisms with four to six increasingly fine-grained stages.
The levels
- Butterfly discovery
Predict and order egg, caterpillar, chrysalis, and adult, observe the completed ring, then explain how eggs begin a new generation.
- Pond changes
Order frogspawn, tadpole, froglet, and adult frog by using visible body changes.
- From seed to flower
Transfer ordered life-cycle thinking from animals to a flowering bean plant.
- Ladybird transfer
Transfer the full idea to an unfamiliar complete-metamorphosis cycle and explain why the final adult links back to eggs.
