Use the skills in a new task
Draw or write four parts for “Earth Systems and Water Stores”—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: River water. Result: hydrosphere. Reasoning: The answer is hydrosphere. In the notes, it means “Earth’s water.” Earth systems interact across boundaries, and one process can connect more than one system. The hydrosphere includes Earth’s water; atmosphere is surrounding gas, geosphere includes rocks and land, and biosphere includes living things. Model limitation: only the stated classroom boundary and supplied observations are established; unmeasured real-world performance remains unverified. Panel 2: Supplied case 1: total water (L)=200; allocated percent=25, using the explicitly named quantities. Allocated water equals total liters multiplied by percent divided by 100. What result follows? Result: 50 L. Reasoning: Substitute the supplied values: (200)*(25)/100 = 50 L. Percent means out of one hundred. Shares depend on the stated total. 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: Lake water becomes vapor. Result: evaporation. Reasoning: The answer is evaporation. In the notes, it means “liquid becomes atmospheric vapor.” Evaporation transfers water from a surface store to the atmosphere. Infiltration moves it into ground pores. Plants take up water and return some through transpiration; matter moves rather than vanishes. 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: River moves sediment. Result: water-rock. Reasoning: The answer is water-rock. In the notes, it means “water changes or moves rock material.” Name both systems and the direction of the interaction. One arrow can simplify a process involving many factors. Supplied fictional records do not establish every effect in a real place. 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.
