Use the skills in a new task
Draw or write four parts for “Waves, Patterns and Information”—one pretend example from each lesson. In each part, show what happened, give your answer, and say which clue helped you. If the question gives numbers, show your working too. Finish with one thing the practice case does not tell us. You may say your answers aloud.
Work on paper or in your own document. Explain the choices you made.
- Choose one pretend example from each of the four lessons.
- Name what each example shows.
- If the example gives numbers, show your calculation and unit. Otherwise, say which clue explains your answer.
- Say that the case details are supplied for practice; they are not your own real-life observations.
- Say one thing the example does not tell us, or one change that could give a different answer.
Compare with a model response
Panel 1: Which scientific label fits the specifically described step or feature? Supplied case: Label highest wave point. Result: crest. Reasoning: The answer is crest. In the notes, it means “highest point of the modeled wave.” A wave carries a disturbance. Wavelength measures repeating spatial separation; amplitude measures displacement from rest. A wave model does not show matter traveling with the pattern over the whole route. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 2: Which scientific label fits the specifically described step or feature? Supplied case: Ripple pattern crosses the diagram. Result: pattern motion. Reasoning: 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. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 3: Supplied case 1: total span (cm)=12; complete wavelengths=3, using the explicitly named quantities. Wavelength equals span divided by complete wavelengths. What result follows? Result: 4 cm. Reasoning: Substitute the supplied values: (12)/(3) = 4 cm. Count full matching-point intervals. The model assumes equally spaced repeats. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 4: Which scientific label fits the specifically described step or feature? Supplied case: Received pair 00. Result: stop. Reasoning: The answer is stop. In the notes, it means “00 in this supplied code.” Digital codes use discrete symbols. In this original paper code, 00 means stop, 01 go, 10 wait and 11 help. The meaning comes from the agreed table. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified.
A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
