Force and Motion Science Experiment

Students predict which balls will need the most and least blowing to begin rolling, then record observations for up to six balls on soft-to-vigorous scales. Two recording pages provide hypothesis, experiment, outcome and conclusion sections. Compare results with predictions and discuss the limits of the test: different balls vary in several properties, so these qualitative observations do not isolate the effect of weight, size or texture alone.
