Grade 9-12

Literacy Activity for Protocol Test

Write a short story from the point of view of a water molecule in the stream you are testing. Describe what causes inconsistent water temperatures that require multiple water temperature measurements.

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.

Accurate water temperature measurements                                              
Tie string to thermometer and rubber band                                              
Place rubber band around wrist                                              
Hold end of thermometer: shake several times                                              
Record temperature                                              
Immerse thermometer in 10+cm of water; wait 3-5 minutes                                              
Read temperature while bulb of thermometer is still in water                                              
Immerse thermometer for one more minute                                              
Repeat previous steps until you have two similar readings; record temps, date, and time                                              
Submit data to GLOBE                                              
Calculate average using temperatures recorded all student groups                                              
If all temperatures fall within 1 C of class average, submit the average value to the GLOBE Student Data Server                                              
Repeat all measurements until all group measurements are within 1 C of class average; submit the average value to the GLOBE Student Data Server
