Use the skills in a new task
Draw or write four parts for “Magnets and Noncontact Forces”—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: N and S poles move closer. Result: attract. Reasoning: The answer is attract. In the notes, it means “poles or material move toward each other.” Magnets can interact without touching. Like magnetic poles repel and unlike poles attract. Magnetism does not attract every metal; supplied materials must be checked by evidence. 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: North faces south. Result: N-S. Reasoning: The answer is N-S. In the notes, it means “opposite labeled poles attract.” A bar magnet has north and south poles. Cutting a magnet does not isolate a single north pole in this elementary model; each piece has both poles. 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: Same magnet and gap; iron versus paper. Result: material test. Reasoning: The answer is material test. In the notes, it means “only tested material changes.” A fair comparison holds distance and magnet constant while changing the material. Do not infer that every shiny or metallic-looking object is magnetic. 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 pulls the paper marker nearer. Result: attraction design. Reasoning: The answer is attraction design. In the notes, it means “opposite poles draw a marker closer.” A proposed design should use the interaction needed for its purpose. Supplied arrow diagrams stand in for hardware. Do not use small magnets, batteries or magnetic toys. 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.
