Supplied materials
- All measurements and observations below are supplied classroom examples. They are not data from actual learners or a claim about a particular real site.
- Paper, drawing space or a browser document.
- Reference card A: early stage containing developing offspring. Reference card B: feeding juvenile stage in this cycle.
- Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Butterfly offspring develops in egg.
- Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Caterpillar eats leaves.
- Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Chrysalis contains transforming insect.
- Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Mature butterfly reproduces.
- Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Young caterpillar feeds.
- Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Insect emerges after pupal stage.
Learn the idea
Many insects pass through egg, larva, pupa and adult stages. The stages have different structures and activities. Not every insect uses this four-stage life cycle.
Egg means early stage containing developing offspring. Larva means feeding juvenile stage in this cycle. Pupa means transformation stage between larva and adult. Adult means mature reproductive stage.
For egg, look for the clue “early stage containing developing offspring.” For larva, look for “feeding juvenile stage in this cycle.” More than one process can happen in a real situation. Answer about the one described in this question.
- Read or listen to the four science words and what each means. Say how the first two differ.
- Choose two of the short cases. Point to the clue that helps you choose a science word for each one. You may draw or say your answer.
- Answer each practice question. Say which clue helped you, then check the explanation.
- Use the extra task to make two examples that show different science words. Draw or say what makes each one fit.
See the method in action
Worked reference-card problem: a card states “early stage containing developing offspring”; a second states “feeding juvenile stage in this cycle.” The first fits egg and the second fits larva. The reason is the described function or change, not the order of the cards or a favorite name. If their descriptions exchange places, their category labels exchange too. Keep the supplied descriptions attached to the correct case.

Helpful tips
- Use the feature “early stage containing developing offspring” to justify egg; do not sort by the name alone.
- Distinguish larva (feeding juvenile stage in this cycle) from a different process occurring in the same situation.
See the answer and explanation
egg
The answer is egg. In the notes, it means “early stage containing developing offspring.” Many insects pass through egg, larva, pupa and adult stages. The stages have different structures and activities. Not every insect uses this four-stage life cycle.
Take it further
Create one new case showing egg and one showing larva. Expected: the first explicitly shows “early stage containing developing offspring”; the second explicitly shows “feeding juvenile stage in this cycle.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
