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: seed begins growing. Reference card B: plant becomes larger.
- Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: A seed sprouts.
- Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: A stem lengthens.
- Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: A plant opens blossoms.
- Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: A pod contains new seeds.
- Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Roots emerge from a seed.
- Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: New reproductive blossoms appear.
Learn the idea
Germination begins growth from a seed. Flowering and pollination can lead to seed production. Reproduction creates a next generation rather than making an existing plant younger.
Germination means seed begins growing. Growth means plant becomes larger. Flowering means plant develops reproductive flowers. Seed production means new seeds form after successful reproduction.
For germination, look for the clue “seed begins growing.” For growth, look for “plant becomes larger.” 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 “seed begins growing”; a second states “plant becomes larger.” The first fits germination and the second fits growth. 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 “seed begins growing” to justify germination; do not sort by the name alone.
- Distinguish growth (plant becomes larger) from a different process occurring in the same situation.
See the answer and explanation
germination
The answer is germination. In the notes, it means “seed begins growing.” Germination begins growth from a seed. Flowering and pollination can lead to seed production. Reproduction creates a next generation rather than making an existing plant younger.
Take it further
Create one new case showing germination and one showing growth. Expected: the first explicitly shows “seed begins growing”; the second explicitly shows “plant becomes larger.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
