Protocols to help in completion of the main protocol
Hydrosphere protocols introduction document.
Instructions are provided on how to select, describe and map a hydrosphere study site.
Students will first measure water transparency at their undisturbed study site using a transparency tube or Secchi disk.
Step-by-step instructions for collection data according to the protocols.
Sheets to be filled out during data collection
Activities to help students learn more about the instruments and protocols
Students construct simple thermometers to understand how and why liquid-in-glass thermometers work.
Students use GLOBE visualizations to display student data on maps and to learn about seasonal changes in regional and global temperature patterns.
Introduction document to the Hydrosphere Investigation Area Learning Activities.
Students measure temperature change in soil, water and air as they are exposed to the heating action of the sun.
Students will make a 3-dimensional model of a catchment basin to understand how water moves through the basin and explore how water is affected when there are changes in the basin.
Students will model the changes in soil water storage over a year.
In the classroom, students practice using the instruments or kits for protocols, exploring the range of measurements and sources of variation and error.
Students will investigate how they use their senses for observation and why we use instruments to collect data.
Students become acquainted with their Hydrosphere Study Site.
Students use GLOBE data and graphing tools to compare the influence of latitude, elevation, and geography on seasonal patterns.
