Mr. Miller would like to negotiate with us to work out a feasible visit. He would like
us to come all day and visit 6 or 7 classes, but realizes this may not be possible.
We might be able to form a team of about 3 people to help him out.

School hours are 8:55 to 15:00.  There are three sets of classes that he would like visited:
1. 8:55 to 11:33  (2? classes)
2. 9:49 to 15:00  (3? classes)
3. 14:10 to 15:00 (1 class)
All classes are science classes.

Mr. Miller is interested in teaching his kids a unit on perception and vision. He could
give preparatory lessons if that were desirable.
