Preparing to Teach

On Monday, I will deliver my first UCLA lecture of the 2012 calendar year.  The audience will be a group of about 120 first year undergrads.  They look young to me.  Is there anything I can teach them?   This is a general education cluster course at UCLA.  Monday's lecture has the following sexy title:
Environmental Economics – An Overview of Behavioral Incentives and Hypothesis Testing:


During my 50 minute presentation, I will cover the following wisdom;


1.  For 15 weeks, the students have heard from leading environmental scientists but not from social scientists.  What do social scientists do all day and why are we useful people for thinking about environmental problems?


2.  Why is social science a harder subject than "real" science?


3.   What is an interesting environmental economics hypothesis?  What evidence would lead us to reject a hypothesis?
