Criteria for Fully-Correct Response

Item 1 - Measure temperatures and record data in table. Student is scored both on proper use of the thermometer and on the quality of data gathering.

Ability to use thermometer. Does not require assistance in proper use of the thermometer (Based on administrator notes on any special assistance provided.)
Total Possible Points: 1

Quality of data gathering. i) Records times and temperatures for 5 or more temperature points per container. ii) Times cover full 10 minutes range. iii) Trend in the temperature is reasonable: temperature declines with time in one or more of the cups. (One cup may be too well insulated to give measurable declines in 10 minutes.)
Total Possible Points: 3

Item 2 - Identify container that keeps hot drink warm longest. i) Identifies correct container (based on administrator notes). ii) Container identified is consistent with the data in table.
Total Possible Points: 2

Item 3 - Explain why container retains heat. i) Relates material of containers to their ability to retain or transfer heat. ii) Includes comparison of different containers based on heat transfer. iii) Logically applies any additional relevant information (stirring, thickness of container, size differences, etc.).
Total Possible Points: 2

Item 4 - Predict best container for keeping ice cream cold. Identifies the same container that best keeps hot drink warm.
Total Possible Points: 1

Item 5 - Explain why container keeps ice cream cold. i) Relates material of containers to their ability to retain or transfer heat. ii) Includes comparison of different containers based on heat transfer. iii) Logically applies any additional relevant information provided (stirring, thickness of containers, size difference, etc.).
Total Possible Points: 2
