Put a beaker of both in a water bath remove and let the students follow the dropping of the temperatures. The glycerin should cool about twice as fast as the water. Of course the high specific heat of water is why everything from  "the watched pot never boils" to why the coldest days of winter or hottest of summer are solstices, etc.

We've ignored change of state.  I suggest adding cooling of something that solidifies, such as solder.

p.s.  the purists can use water in a freezer.
