Among the "new breed" chemistry courses designed for sec-
ondary application, the 'chemical materials study' (CHEMS)
is a favorite which continues to be adopted, adapted, re-
vised, and rewritten. CHEMS LAB 5 is designed to contrast
the energy involved in a phase change with that of a chemi-
cal change using very simple materials and equipment. It
also provides early experience in quantitative investigation
by dealing with the uncertainly of measurement, and the
ideas of accuracy and precision.
