About 12 minutes, plus any extended practice
Supplied materials
- For younger learners, an adult may read each direction aloud; pointing, drawing and spoken explanations count as responses.
- Paper, drawing space or a browser document.
- Reference card A: helps green plants make food. Reference card B: enters a plant and supports its processes.
- Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Sunlight reaches green blades.
- Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Rain wets a plant’s surroundings.
- Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: An underground part takes in water.
- Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: A flat green part catches light.
- Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: A lamp supplies light to leaves.
- Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: A stem receives water from below.
Learn the idea
Most familiar green plants use light to make food and need water and air. Soil can support roots, but plants do not eat soil like an animal eats a meal.
Light means helps green plants make food. Water means enters a plant and supports its processes. Root means plant part taking in water from its surroundings. Leaf means plant part that often captures light.
For light, look for the clue “helps green plants make food.” For water, look for “enters a plant and supports its processes.” 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 “helps green plants make food”; a second states “enters a plant and supports its processes.” The first fits light and the second fits water. 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 “helps green plants make food” to justify light; do not sort by the name alone.
- Distinguish water (enters a plant and supports its processes) from a different process occurring in the same situation.

light
The answer is light. In the notes, it means “helps green plants make food.” Most familiar green plants use light to make food and need water and air. Soil can support roots, but plants do not eat soil like an animal eats a meal.
Take it further
Create one new case showing light and one showing water. Expected: the first explicitly shows “helps green plants make food”; the second explicitly shows “enters a plant and supports its processes.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
