University of Fort Hare
Heat or cool water and observe how the temperature changes.
Laboratory information
The Water Heating and Cooling Curves of Water laboratory allows students to heat or cool a mass of water with different intensities, and measure the temperature continuously. It is thus possible to create a plot with the resulting temperature-time curves, and thus obtain conclusions regarding the transfer of energy and matter state changes.
What students do
Ready lesson plans
Preview classroom-ready activities that guide students through the real laboratory.
A 26-minute science mission on the core route, or about 31 minutes with the optional graph: use a real run to investigate why a thermometer's reading barely changes while ice is being heated.
Students use the UFH Water Heating and Cooling Curves remote lab to read real thermometer-video frames, compare high heat, low heat, and cooling, graph temperature against time, and explain phase-change plateaus.
