Your instructor will fill each of your bottles with hot water. Seal the lids tightly and do not open them since water at this temperature can burn skin. Place a thermometer in one bottle and record the temperature in the table below. At the beginning, all of your bottles are the same temperature so record this number in all four boxes. Wait 10 minutes and record in the table below the temperatures of all the bottles. Calculate the change in temperature and enter in the appropriate column of the table below. Answer the questions below Results and Discussion Note: With the help of your teacher, discard the water and set aside your bottles for Day 3. Day 2 Data Collection With no fan blowing, record your data: Insulation Material Beginning temperature Temperature Change in (and # of layers) (show units!) after 10 minutes temperature Control (no insulation) Day 2 Results and Discussion What material kept the water hottest? Is this what you expected? Day 3 Procedure: Test 1 - Cooling with Fan Position the same bottles used the previous day in front of a fan. Your instructor will fill each of your bottles with hot water.
