Phase Changes Lab


Summary:
Today in class, students completed the Phase Changes Lab. Because nothing enthralls 8th graders like watching ice melt! They started off with a thermometer frozen within a block of ice, then put it into a beaker, and then heated it for 30 minutes. All the while, they kept track of the temperature.

Their graph ended up looking like the one above. As the ice warmed, it’s temperature rose, up until its melting point. Then the temperature plateaued during the melting process. Then it rose again, followed by another plateau during boiling. Afterward, students completed the post-lab questions for homework.
