This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.
List of all Hydrosphere Mini Lessons
Students review the NASA video showing biosphere data over the North Atlantic Ocean as a time series animation displaying a decade of phytoplankton blooms and answer questions that follow.
Use the Data Literacy Map Cubes to familiarize yourself with and interpret the model.
This is the first of a four-part series on the water cycle, which follows the journey of water from the ocean to the atmosphere, to the land, and back again to the ocean. Students review the video and answer questions.
The world's ocean is heated at the surface by the sun, and this heating is uneven for many reasons.
Students will read an article and/or watch a video clip about the effects of El Niño. They will then answer questions about the phenomenon and its effects on global health.
The Earth's system exemplifies stability and change. Change and rates of change can be observed and quantified over very short or long periods of time and various spatial scales (e.g., from landscape level to global processes).
Students will investigate the differences in sea surface height during an El Niño event by creating a model with gelatin, sherbet and whipped creme.
This mini lesson helps students visualize how the Hydrosphere and Cryosphere interact to produce changes in land and sea ice.
