What is sea-level rise and how does it affect us? This "Teachable Moment" looks at the science behind sea-level rise and offers lessons and tools for teaching students about this important climate topic. 

GLOBE protocols and learning activities that complement the Ocean Circulation Patterns phenomenon through hands-on investigations are detailed. These protocols can be used to build a basis for understanding the principles of salinity and water temperature which are drivers of the ocean circulation patterns.

Explore and connect to the GLOBE Urban protocol bundle. 

GLOBE protocols and learning activities that complement the El Niño Southern Oscillation phenomenon through hands-on investigations are detailed.

In this activity, you will use an inexpensive spectrophotometer* to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples.
