Students in a middle school science class are working in pairs to experiment with pendulums. Their teacher, Ms. Oreski, has asked them to answer this question: What one or more things determine how fast a pendulum swings? She also suggests three factors they might study in their experimentation: a pendulum's weight, its length, and the force with which it has been pushed. Each pair has 2 feet of string and various objects that can be tied to the bottom of the string. Each pair also has a few sheets of paper on which to record various hypotheses and observations. Does this task impose a reasonable cognitive load?
