Hi all,
Once I heard about a class that had a project related to time.
The first thing they did was mark on the wall the exact place of the
shadow of a marker they had put on the (nearly south) window each

Dear Frank and All,
Your observations are very good, the number of adults and children that can
properly use even a ruler seems small. Your using a vertical pole as a
gnomon is worthwhile. A knowledgeable and able person could establish a
dial center offset toward the equator in such a way tha

Dear All,
I have read the correspondence about Oscar with
much interest. "How," it is almost asked, "can
we used sundials as a means of interesting
children in science?"
Like Tony Moss, and no doubt several others on

Just to correct some wrong information..There was a book for
schools written through the auspices of the Bristish Sundial Society by a group
of members of which I was only one of nine on the team. It was called "Make a

This will help Oscar and lower my blood pressure but the material
