Types of Metamorphosis
Complete vs incomplete metamorphosis. Complete: egg → larva → pupa → adult (butterflies, beetles, flies). Incomplete: egg → nymph → adult — the nymph looks like a small version of the adult and moults as it grows (grasshoppers, dragonflies, crickets). Why do some insects transform completely while others grow gradually?

Teaching Table
Set out your lesson
Compare metamorphosis sequences and avoid calling a pupa a dead or inactive object.
Can discuss the supplied example in an accessible mode; adapt directions without supplying the target answer.
Check the learner can follow the model with support before moving on. Source prerequisite ordering is not learner mastery; return to prerequisite work when needed.
Use process cards; no insect collecting or disturbing pupae. Open S first, G together, then T alone; put S and G away before T. Keys stay adult-only. No purchase or printing is required; an unavailable physical observation remains pending, not passed.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.

- partial: Can {{name}} explain the difference between a butterfly's life cycle and a grasshopper's — why the caterpillar looks nothing like the butterfly, but a baby grasshopper already looks like a small grasshopper?
