Jim, Try putting some data into a spreadsheet and graph it. Have your student make conjectures what kind of function would fit the data. (You can generate the data intitially from a function, or copy it from some source - book, newspaper, etc.) Your students could put the function they want to try into the spreadsheet and generate data and plot it. A discussion of how various functions (equations) represent the data better or worse might be interesting. Have fun.
