Benchmark Question: How do living things maintain a
stable internal environment?
Focus Question: What steps must be taken to maintain
a stable system?
Working in groups without
any verbal communication, students should maintain a constant temperature
of a beaker filled with hot water. Using two beakers of water, one large
and one small, a thermometer, cold water, and a heat source, students
should maintain the large beaker of water at approximately 50oC.
Students then should describe the process their group used to maintain the
constant temperature. (If available, use probes and graphing programs; this
will give students more accurate feedback.)
