In seeking a testable hypothesis, we found the statement below in
the book The
Hand-Sculpted House by Ianto Evans. We chose this statement as
Heat flows through cob at the rate of an inch per hour.
a. we are able to measure temperature changes over time at various
depths in the cob wall
b. we heat the interior of the structure for a certain length
of time, then discontinue the heating period
What is the time lag between the peak temperatures at different
depths in the wall?
This time lag should help us determine the rate of heat transfer
through the cob wall.
