Use the skills in a new task
Draw or write four parts for “Parts Have Functions”—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: Below-ground water-taking part. Result: root. Reasoning: The answer is root. In the notes, it means “takes in water from surroundings.” Roots take in water and dissolved minerals. Stems support and transport. Leaves commonly capture light; flowers are reproductive structures. Plants differ, so these are familiar flowering-plant examples. 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: Bird lifts using feathered limb. Result: wing. Reasoning: The answer is wing. In the notes, it means “helps the supplied bird fly.” Body parts perform functions. These supplied descriptions tell you what a part does for a named animal. The same-looking part need not do exactly the same job in every species. 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: Bird reacts to a call. Result: hearing. Reasoning: The answer is hearing. In the notes, it means “detecting the supplied sound.” Animals gather information using senses and can respond. A stimulus is a change that can be detected. We analyze fictional observations, not an individual’s medical condition. 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: Goal is attach to fabric. Result: hook. Reasoning: The answer is hook. In the notes, it means “modeled on a burr that attaches.” Engineers can take inspiration from organisms without making exact copies. Match the stated function. A paper drawing is only a proposal, not proof of performance. 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.
