Question: Anna wants to compare the fat in walnuts and peanuts. Using only the results from her experiment, how will Anna know which one, walnuts or peanuts, has more fat? The experiment has the following procedure: Measure out equal masses of walnuts and peanuts (for example, one gram). Smash the samples uniformly in the same size area on brown paper. Wait (the same time for each).
Reference answer: Anna should compare the size of the grease spots. The sample with the larger grease spot has more fat.
