Rainfall Protocol

For elementary grades, include the following:
The rain gauge has 1 cm of precipitation. The overflow tube has 12 cm of precipitation. What is the total amount of precipitation since the last measurement? (NCTM Standards: Numbers & Operations 3.1, 3.2, 3.3, 3.4, 3.5, 3.6)

For middle school grades, include the following:

The rain gauge has 0.5 cm of precipitation. The overflow tube has 12.8 cm of precipitation. What is the total amount of precipitation since the last measurement? (NCTM Standards: Numbers & Operations 3.1, 3.2, 3.3)

For high school grades, include the following:

The rain gauge has 3.2 cm of precipitation. The overflow tube has enough liquid in it to fill the 10 cm rain gauge twice and the third time an additional 1.5 cm is measured. What is the total amount of precipitation since the last measurement? (NCTM Standards: Numbers & Operations 3.1, 3.2)

Air Temperature

For elementary grades, include the following: What is the average air temperature when the maximum temperature is degrees C and the minimum temperature is 15 degrees C? (NCTM Standards: Numbers & Operations 3.1, 3.2, 3.3, 3.4, 3.5, 3.6)

The maximum air temperature is 25 degrees C, the minimum air temperature is 15 degrees C, and the current temperature is 18 degrees C. The current temperature is how much colder than the maximum air temperature? How much warmer than the minimum temperature? (NCTM Standards: Numbers & Operations 3.1, 3.2, 3.3, 3.4, 3.5, 3.6)

For middle school grades, include the following:
What is the average daily air temperature if the maximum temperature is 30 degrees C and the minimum temperature is 15 degrees C? (NCTM Standards: Numbers & Operations 3.1, 3.2)

For high school grades, include the following:
Use the relationship: degrees F = [9/5 (degrees C)] + 32 to translate these temperatures in degrees C to degrees F:
maximum temp = 34.5 degrees C
minimum temp = 18.1 degrees C
current temp = 22.3 degrees C
(NCTM Standards: Numbers & Operations 3.1, 3.2)

Use the relationships
degrees F = [9/5 (degrees C)] + 32 AND
degrees C = (degrees F – 32) x (5/9)
to calculate the temperature at which degrees C = degrees F
(NCTM Standards: Algebra 2.1, 2.3)

Precipitation Solid

For elementary grades, include the following:
It has been 4 days since you measured snowfall at the study site. 24 cm of snow has accumulated on the snowboard. What is the average amount of daily snowfall for this time period? (NCTM Standards: Numbers & Operations 3.1, 3.2, 3.3, 3.4, 3.5, 3.6)

For middle school grades, include the following: It has been 4 days since you measured snowfall at the study site. 21 cm of snow has accumulated on the snowboard. What is the average amount of daily snowfall for this time period? (NCTM Standards: Numbers & Operations 3.1, 3.2, 3.3)

For high school grades, include the following: 17.3 cm of snow has accumulated on the snowboard. Today is February 3rd. Your last snowfall measurement was on January 30th. What is the average amount of daily snowfall for this time period? (NCTM Standards: Numbers & Operations 3.1, 3.2)
