 1 point for the correct substitution into the equation.
(Units not required)
B. Correct Units
 1 point for units recorded as cm/min.
C. Rounding
 1 point for answers recorded to the nearest tench of a cm/min.
D. Correct Calculation
 1 point for an answer within +/0.2 cm/min.
Note 1: Base student responses on student data
Task 7. 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
 1 point for both of the axes correctly labeled (naming
variable)

 1 point for units recorded on both axes.
C. Appropriate Scale
 1 point for use of appropriate scale for the data.
D. Data correctly plotted
 2 points for plotting 7 or more points correctly.
 1 point for plotting 46 points correctly.
 No credit is given for fewer than 3 points plotted correctly.

2 points total

Standard: The student will analyze and describe the plotted
results.
Criteria:
 2 points for an accurate, logical description using complete
sentences.
 1 point if the answer is correct but not in a complete sentence
