Students will identify and describe the relationship between watersheds and phytoplankton distribution. 

Students identify patterns in chlorophyll concentration data to formulate their explanations of phytoplankton distribution. 

This graphic organizer may be used to help students analyze the processes and components of Earth System phenomena.

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.

In this lesson, students will investigate the drivers of climate change, including adding carbon dioxide and other greenhouse gases to the atmosphere, sea level rise, and the effect of decreasing sea ice on temperatures.

In this activity, students explore three indicators of drought are: soil moisture, lack of precipitation, and decreased streamflows. Students investigate each of these parameters develop a sense for the effects of drought on land.
