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 a still toy begin moving. Reference card B: stops a toy at the finish.
- Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Toy stays still at the start.
- Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Toy passes the finish line.
- Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Toy must bend around a corner.
- Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Toy shoots beyond a nearby target.
- Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Toy needs to begin rolling.
- Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Toy needs a stop at its goal.
Learn the idea
Pretend records show one change at a time. Choose the change matching the observed problem. No toy building or small objects are needed; draw the improvement.
Start push means helps a still toy begin moving. Catch barrier means stops a toy at the finish. Side guide means changes a toy’s path. Smaller push means can reduce an overly strong launch.
For start push, look for the clue “helps a still toy begin moving.” For catch barrier, look for “stops a toy at the finish.” 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 a still toy begin moving”; a second states “stops a toy at the finish.” The first fits start push and the second fits catch barrier. 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 a still toy begin moving” to justify start push; do not sort by the name alone.
- Distinguish catch barrier (stops a toy at the finish) from a different process occurring in the same situation.
See the answer and explanation
start push
The answer is start push. In the notes, it means “helps a still toy begin moving.” Pretend records show one change at a time. Choose the change matching the observed problem. No toy building or small objects are needed; draw the improvement.
Take it further
Create one new case showing start push and one showing catch barrier. Expected: the first explicitly shows “helps a still toy begin moving”; the second explicitly shows “stops a toy at the finish.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
