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
