Distinguish wave motion from material motion
Distinguish wave motion from material motion using supplied evidence and a solved model.
About 18 minutes, plus any extended practice
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: disturbance moves along the model. Reference card B: marked piece moves locally.
- Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Ripple pattern crosses the diagram.
- Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Marked rope spot moves upward.
- Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Rope lies on its unshifted line.
- Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Wave moves a distant modeled receiver.
- Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Peak travels along the rope drawing.
- Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Marked spot oscillates locally.
Learn the idea
In the supplied rope model, a marked piece moves up and down while the wave pattern moves along. Water surface models are simplified and real particle motion can differ.
Pattern motion means disturbance moves along the model. Particle motion means marked piece moves locally. Rest position means location without displacement. Energy transfer means disturbance can deliver energy elsewhere.
For pattern motion, look for the clue “disturbance moves along the model.” For particle motion, look for “marked piece moves locally.” 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 “disturbance moves along the model”; a second states “marked piece moves locally.” The first fits pattern motion and the second fits particle motion. 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 “disturbance moves along the model” to justify pattern motion; do not sort by the name alone.
- Distinguish particle motion (marked piece moves locally) from a different process occurring in the same situation.
See the answer and explanation
pattern motion
The answer is pattern motion. In the notes, it means “disturbance moves along the model.” In the supplied rope model, a marked piece moves up and down while the wave pattern moves along. Water surface models are simplified and real particle motion can differ.
Take it further
Create one new case showing pattern motion and one showing particle motion. Expected: the first explicitly shows “disturbance moves along the model”; the second explicitly shows “marked piece moves locally.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
