Students learned how temperature can effect the solubility (dissolving) of an object. We put a chicken bouillon cube in three different cups of water. The first cup contained 28 degree Celsius water, second cup was 68 degree Celsius and the last one was near boiling at 85 degrees. Temperature was our variable in this lab. Students mastered the concept that the greater the temperature of the solvent (water), the faster a solute (bouillon cube) will dissolve.
I hope you enjoy learning how the garden changes throughout the school year.
