2. Graph 5 points total

Allow 1 point for each of the following;

  • Appropriate title
  • Axes labeled with correct variables (units included)
  • Appropriate scale
  • Points plotted accurately
  • Curves are appropriate to data trend

3. Data Transfer from Table 2 points total

Allow 1 point for each of the following;

  • Correct 6 minute dry tube reading based on data collected
  • Correct 6 minute wet tube reading based on data collected

4. Graph Interpretation/Prediction 2 points total

Allow 1 point for each of the following;

  • Corresponds to student’s dry tube graph at 9.5 minutes
  • Corresponds to student’s dry tube graph at 9.5 minutes

5. Extrapolation Prediction 3 points total

  • Allow 1 point for correct temperature prediction based on student’s graph/data
  • Allow 2 points if the explanation refers to extrapolation from graph or data and is in complete sentences
  • Allow 1 point if the explanation refers to extrapolation from graph or data and is not in complete sentences
  • Allow 0 points if explanation is not correct even if it is in complete sentences

6. Data Interpretation/Comparison 4 points total

Allow 1 point for each of the following;

  • States pattern for dry tube readings
  • States pattern for wet tube readings
  • States relationship/comparison
  • Correct statement or statements and all in complete sentences

7. Data Explanation 2 points total

Allow 2 points if the explanation is correct and in complete sentences

Allow 1 point if the explanation is correct, but not in complete sentences

Allow 0 points if the explanation is incorrect even if it is in complete sentences

    Correct statements may include:

  • The wet tube is cooled by evaporation
  • Heat energy is removed more quickly from water in wet tube
  • The dry tube temperature is maintained by better insulation

8. Comparison 3 points total

Allow 1 point for each of the following;

  • States correct comparison between wet paper towel and perspiration on human skin
  • Relates to process/role of evaporation to cooling/heat loss
  • Correct statement or statements and all in complete sentences

Allow 0 points if the explanation is incorrect, even if it is in complete sentences.
