Maximum Score - 24 Points


Task 3. Data Table 7 points total

Standard: The student will measure the distance to the bottom of the box and record these data accurately and precisely in a data table.

Criteria:

  • 1 point for each of the five correct measurements (+/- 1.0 cm of teacher's value).
  • 1 point if all measurements are rounded to the nearest tenth of a centimeter.
  • 1 point if all of the measurements are labeled with correct units.

4. and 5. Graph 6 points total

Standard: The student will use the data from his/her table to draw a graph representing a profile of the surface of the bottom of the box.

Criteria:

  • Allow 1 point for each of the five correctly plotted points.
  • 1 point if the line is correctly drawn. Dot to dot or best fit curve may be acceptable.

Question 6. Shape Description 2 points total

Standard: The student will describe the shape of the bottom of the box using his/her data to draw inferences about the profile of an unobservable surface.

Criteria:

  • 2 points if the statement is descriptive and is generally consistent with the table and graph.
  • 1 point if the statement is partially correct.

Question 7. Estimation 4 points total

Standard: The student will predict the elevation of an unknown value between two known values, and justify that prediction. The prediction should be based on the student's graph.

Criteria:

    • 2 points for correctly estimating the value and unit at spot four (4), based on their line graph (+/- 0.1 cm).
    • 1 point for correct value (+/- 0.2 cm).
    • 2 points for a reasonable explanation of their prediction.
    • 1 point for a partial explanation of prediction.

Question 8. Model Drawing 1 point total

Standard: The student will draw a two dimensional representation of the bottom of the box based on their data.

Criteria:

  • 1 point for a drawing which matches the graph in #3.

Question 9. Select Drawing 2 points total

Standard: The student will interpret the data from the graph to make an accurate inference.

Criteria:

  • 2 points if both and only graphs A and D are selected.
  • 1 point if only graph A or D is selected, with no incorrect selections.
  • 1 point if both graphs A and D are selected, and one additional incorrect selection is made.
  • 0 points if 2 incorrect graphs are selected.

Question 10. Explanation of limited stick 2 points total

Standard: The student will explain the results of the limits of measurement.

Criteria:

  • 2 points if a logical explanation is given that the graph would reflect the lack of data below the limits of the measuring stick.
  • 1 point for a partial explanation
