Interested in engaging your students with real-time NOAA data? In this module, designed for 6-12th grade classrooms, students evaluate changes in sea surface temperature over space and time and investigate how El Niño affects phytoplankton & species distribution in the eastern Pacific Ocean. The module offers lessons at five different levels, beginning with basic graph interpretation (Levels 1 & 2) and building towards activities that challenge students to ask questions and develop their own data investigations (Levels 4 & 5).
