Students use Phytopia: Exploration of the Marine Ecosystem, a computer-based tool, to investigate various phytoplankton species and topics relating to phytoplankton biology. 

This unit, created through the NASA Goddard Institute for Space Studies (GISS) Climate Change Research Initiative (CCRI), helps students learn about each component of the energy budget formula and how the contribution of each component changes based on the location and the time of the year. 

Students will explore the Nitrogen Cycle by modeling the movement of a nitrogen atom as it passes through the cycle.
