Scoring Rubric
Maximum Score - 21 points
| Task 1. Data Table |
3 points total
|
Standard: The student will accurately record
data on a data table.
Criteria:
- Refers to 10 minutes of recorded data or the time
it takes for the glop to flow 30 cm. (Note that the rate of
flow will depend on your glop recipe.)
- Allow 1 point for recording the data at each interval.
- Allow 1 point for sequential and consistent data at each
interval.
(See Comment 1.)
B. Recorded Accurate Data
- Allow 1 point for all data accurately recorded to the nearest
tenth of a cm.
| Task 2. Graph |
6 points total
|
Standard: The student will correctly set up graph axes,
plot data points, and draw a line graph.
Criteria:
A. Axes Labeled
- Allow 1 point for both of the axes correctly labeled
(naming variable).
B. Correct Units
- Allow 1 point for units recorded on both axes.
C. Appropriate Scale
- Allow 1 point for use of appropriate scale for the data.
D. Data correctly plotted
- Allow 2 points for plotting 15 or more points correctly
(or to the end of 10 minutes).
- Allow 1 point for plotting 7-14 points correctly (50% of
points plotted correctly.)
- No credit is given for fewer than 7 points plotted correctly.
E. Line Correctly Drawn
- Allow 1 point for either a "best fit curve" or
"dot to dot."
| Task 3. Rate of Flow |
6 points total
|
Standard: The student will apply mathematics to calculate
rate of flow and show the procedures used. (See Comment 2.)
Criteria:
A. Calculation of rate: First three minutes
- Allow 1 point for the correct substitution in formula.
- Allow 1 point for the correct calculation.
B. Calculation of rate: Last three minutes
- Allow 1 point for the correct substitution in formula.
- Allow 1 point for the correct calculation.
C. Correct Units
- Allow 1 point for correct units in both A and B.
D. Recorded to the nearest tenth
- Allow 1 point if both A and B are rounded to the nearest
tenth of a cm/second.
| Task 4. Comparison |
4 points total
|
Standard: The student will write an inference based on
an observation of a change in the rate of flow for the material.
Criteria:
A. Reasons
- Allow 2 points for a logical response based on the student's
data, using complete sentences.
- Allow 1 point for a logical response not in a complete sentence.
B. Graph Interpretation
- Allow 2 points for an accurate description in a complete
sentence of how the graph shows the similarity or difference
in rates of movement.
- Allow 1 point for an accurate description not in a complete
sentence.
Example: A steeper slop indicates faster movement;
a gentle slope indicates slower movement.
| Task 5. Prediction |
2 points total
|
Standard: The student will write an inference based on
an observation of a change in the rate of flow for the material.
Criteria:
A. Graph
- Allow 1 point for showing a more rapid rate of motion of
glop on the graph. (Consistent with student data.) If distance
is on the vertical axis, then the correct answer would be
above the line.
B. Model Application
- Allow 1 point for a reasonable answer. Refer to the examples
below. These are possible answers but not the only answers.
- heavy precipitation; man's influence on changing slope;
flooding; increased amount of water that influences sediment;
removal of vegetation, etc.
Comments:
Comment 1: Correction for error: If a student has accounted
for an interruption in his/her data, and not this, full credit should
be awarded. (ex. If a student misses a reading, and indicates this
in place of a reading, credit should be given.)
Comment 2: Double jeopardy: The student should not be penalized
twice for the same error. Answers should be consistent with, and
based on, data recorded in earlier parts of the question.
