Sixth-Graders Track Temperature’s Effect on Density

During a science lab at the middle school, sixth-grade students examined how temperature affects the density of fluids, including liquids and gases. In order to conduct the experiment, students used water tanks separated with plastic dividers, pouring hot water that was dyed red on one side of the tank and cold water that was dyed blue on the other. When the dividers separating the hot and cold water were removed, students were surprised to see the cold blue water slide under the warm red water.

“Through this lab, students were able to apply this information to their weather unit,” said teacher Jamie Carlino. “This helped them understand how air masses of different temperatures react when they collide.”
