E.   Metaphors of science
§There are two metaphors for science
§1.  Science is like a game of 20 Questions
§I have something in this bag: Try to guess what it is by asking me only yes or no questions. 
§Is this a good metaphor of science?
§It looks like science because you formulate ideas or hypotheses, test them out by asking questions, and then revise them when you get an answer.
§This is just like the “scientific method” you learned about since elementary school.
