Today’s Agenda:

  1. Lab Protocol

  2. Investigation Questions:

    • How does time affect cooling?

    • How does air temperature affect cooling?

  3. Experimental Method:

  4. Student groups of 2-3

  5. Each group will collect data at an assigned station, tracking the change in temperature of a hot sample of water over time for 30 minutes.

  6. 200 ml samples of hot water in 250ml beakers will be mounted on lab stands and measured with lab thermometers every minute.

  7. Data will be recorded by each student.

  8. The entire class will also collect data on one sample placed in a refrigerator during the experiment.

    • A thermometer will be used to measure the air temperature of the refrigerator..

    • A second thermometer will measure the water temperature of the sample.

  9. All data will be entered into a spreadsheet for analysis.
