Activity for Protocol Test
Five
student groups measured the water temperature at their study
site. Their measurements were:
10 degrees
C
10 degrees C
9 degrees C
11 degrees C
10 degrees C
What
is the average temperature that the class should record on
their GLOBE data sheet?
(NCTM Standards: Numbers & Operations 3.1, 3.2, 3.3, 3.4,
3.5, 3.6)
Calculate
the range of percent error in these measurements
(NCTM Standards: Numbers & Operations 3.1, 3.2; Data Analysis
& Probability 3.2, 3.3; Measurement 2.1)
Water
Temperature Protocol Test
The Temperature
protocol test assesses students' ability to collect accurate
water temperature measurements and to post their measurements
to the GLOBE database.
