Some ice and a little bit of water are placed in a glass beaker.  The beaker is placed on a heater.  Eventually the ice melts.  The heater continues to heat the liquid water.  Eventually the water begins to boil.  The heater continues to heat the boiling water.
\\
Sketch a graph that illustrates your prediction for the way the temperature of the contents of the beaker change during this process.

**Instructor Comments**
\\
This diagnostic question provides a nice segue between the unit on thermal phenomena and the unit on motion graphs. The students have an opportunity to apply their knowledge of heat and temperature phenomena in a new context, graphing.
