3-D Molecules Explain Heat Energy & H20

on November 26, 2014

Fourth grade students wondered whether salt dissolved more in warm water or cold water.  They completed an experiment that tested the claim that more salt would dissolve in warmer water.  Students found more salt was able to fit in the warmer water.  The students understood that water molecules that are warmer are more spread out and moving faster.  We used 3-D molecule models to show how water spreads out and condenses depending on temperature.
