Melissa Lau spent a month in the tundra ecosystem gathering data using a device called a Greenseeker. This device measures exactly how green a plant is by calculating its NDVI or Normalized Difference Vegetation Index. In this lesson, students will explore light waves, how they interact with plants, and find out how green is green.
In this introductory lesson, students read an article about Arctic Ocean ecosystems and then play a board game in which they take on the role of researchers.
Objectives
The purpose of this introductory activity is to:
* Identify the main components of complex arctic ecosystem and describe predator/prey relationships between phytoplankton, ice algae, zooplankton, bowhead whales, polar
In part one of this two-part lesson students work in pairs to explore the effects of salinity on ocean stratiļ¬cation using a simple plastic shoebox-sized container in which they create a mini-ocean environment. Students will apply what they learn in the lab setting along with information gained in several online articles to a basic understanding of the Global Conveyor
