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
