The preschool students experimented with different household kitchen items to determine which ones dissolve in water. They started with four cups half full of water.
In one cup they poured in one packet of sugar and stirred it up in the water. The sugar ‘disappeared’ and dissolved.
In the second cup they sprinkled a teaspoon of cinnamon. It did not dissolved and left the water looking dirty, but it smelled good.
In the third cup they sprinkled a teaspoon of cream of tartar. It made the water cloudy and did not dissolve very well.
In the last cup they sprinkled a teaspoon of salt. The salt did not dissolve and left granules on the bottom of the cup.
The preschool students were able to see what dissolves in water and how our water supply can be affected if not properly taken care of.
