To do this Tom we would need to come up with and activity and the pre- and post-tests.  What do we want  the students to know when we are done?   How do we make it relevant to  students daily lives?    I like the idea of a 1 or 2 day mini class on scanning?  With only 2 STM’s  how do we get a class of 30 students to participate?

I will have to look at the standards to see where this would fit.    Where does scanning tunnelling microscopy fit in an energy them?   Maybe it would fit better in the electrical energy and magnetic energy unit?

Just thinking aloud,  why do we need to scan any surface at an atomic level?   What does it tell us that we can’t see with the SEM or the AFM?

The more I run the STM the more questions I have.   I come up with more questions than answers.  we have started a schedule of operation.   I think anyone could begin to run the STM on simulation.  But to actually scan a sample of something that we want to discover something about is much more difficult because you are not sure what you are supposed to see.  I’ve worked with this one for 6 weeks and I still do not feel  confident.  I do not know how to verify my data.   Analysis of the scans  is still a mystery.
