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.
The local on-line newsletter interviewed Mr. Wood over the phone and talks about the upcoming expedition to the interior tundra of Alaska and how it will involve the students at Talbert Middle School in Fountain Valley.
