This mini-lesson features time-series graphs of mean salinity at the surface for the Arctic and Antarctic regions. A series of questions guides students in their analysis.

Students review a visualization showing a global view of the top-of-atmosphere longwave radiation from January 26 and 27, 2012. They review the supporting text and analyze the data in the visualization to answer questions.

This mini lesson engages students by watching a NASA video related to seasonal chlorophyll concentration as it relates to net radiation using NASA's Aqua satellite. Students will examine the model and answer the questions.

Students observe seasonal images of Monthly Leaf Area, looking for any changes that are occurring throughout the year.

Students compare climographs for two locations to determine the most likely months to expect the emergence of mosquitoes in each location.

Students analyze the stability and change of sea level after watching a visualization of sea level height around the world. 

This mini lesson engages students in watching a NASA video related to accumulated dust that makes the trans-Atlantic journey from the Sahara Desert to the Amazon rainforest using NASA's CALIPSO satellite. Students will examine a model and answer questions related to dust transport and the introduction of phosphorus to the soils of the Amazon.

Watch NASA videos about aerosols and volcanic ash.

Students analyze a graph that illustrates the change in global surface temperature relative to 1951-1980 average temperatures.

Students interpret a graph of surface temperatures taken from city districts and other types of communities.
