Making Inferences

Puzzle icon

After you have observed your instructor perform a demonstration or simulation, or watch a movie, you will often be asked to make some inferences; that is, you’ll be asked to try to make sense of what is happening, based on your ideas and the evidence provided by your observations.

Whenever you are being asked to make an inference you will see this puzzle icon, Puzzle icon, in front of the question.

These inferences could be as simple as interpreting a speed-time graph to determine what the motion of an object was like in a small part of the demonstration, or you could be asked to make a general statement about the way the world works, based on evidence from several demonstrations. You should be certain that any inferences you make are indeed supported by evidence, and you will often be asked to explain how this is so.
