Sea Level Rise: Protocols and Data Sheets

Wanda Doing GLOBE

Students and scientists investigate hydrology through the collection of data using measurement protocols and using instruments which meet certain specifications in order to ensure that data are comparable. Learning activities aid in the understanding of important scientific concepts, the understanding of data and data collection methodologies. 

 pH Protocol: Students will use either a pH meter or pH paper to measure the pH of water. If using the pH meter, the meter needs to be calibrated with buffer solutions that have pH values of 4, 7, and 10.  pH Protocols

 Salinity Protocol: Students will use a hydrometer to measure the specific gravity of the water sample, and use a thermometer to measure the temperature. With these two values, students will use tables to determine the salinity.

 Water Temperature Protocol: Students use a thermometer or probe to measure the temperature of water.
