====== Recall Gauss' Law ======

===== Prompt =====

** "Write down Gauss' Law." **

===== Context =====

This [[strategy:smallwhiteboard:|SWBQ]] can be done as an introduction to the
Gauss' Law lecture. It is an opportunity for the instructor to find out what
the students already know about Gauss' so as to focus the succeeding
lecture/discussion appropriately.

===== Wrap Up =====

Since most students remember something about this law, one can construct the
answer on the front board from the bits and pieces that they remember,
emphasizing why each of the pieces is important and talking about the geometry
of each piece.

  * emphasize that Gauss's law holds for ANY electrostatic field and ANY (imaginary) surface
