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.

Helping students build their understanding of Earth's spheres and how they are connected is difficult.  Review the graphics to help identify the parts of the Earth System and the processes that connect them at the local, regional, and global scales.

Working in teams, students learn how a STEM professional uses STEM practices to solve real-world problems, design a STEM Career Connection Badge that highlights their takeaways about that profession, and build a training station to teach their classmates during a STEM Career Conne

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.
