Use the skills in a new task
Draw or write four parts for “Weathering, Erosion and Earth Hazards”—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: Ice breaks rock into pieces. Result: physical weathering. Reasoning: The answer is physical weathering. In the notes, it means “rock broken without changed composition.” Weathering changes or breaks rock in place. Erosion transports particles, and deposition accumulates them elsewhere. These may occur together, so explain the observed step precisely. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 2: Supplied case 1: initial height (mm)=25; final height (mm)=21, using the explicitly named quantities. Recorded height loss equals initial height minus final height. What result follows? Result: 4 mm. Reasoning: Substitute the supplied values: (25)-(21) = 4 mm. Subtract final from initial. A difference alone does not identify the process. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 3: Which scientific label fits the specifically described step or feature? Supplied case: Fault motion shakes ground. Result: earthquake. Reasoning: The answer is earthquake. In the notes, it means “ground shaking from sudden fault motion.” A hazard is a potential source of harm; damage also depends on exposure. Use supplied diagrams. Do not visit a hazard site or test structures in dangerous conditions. 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: Same modeled shaking used each run. Result: test condition. Reasoning: The answer is test condition. In the notes, it means “how the model is challenged.” A model solution must match its stated hazard and include limitations. A reduced model loss is useful evidence but does not certify a real building, slope or emergency plan. 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.
