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 journal assignment involves students in current science research. Through the teacher’s journals, they will learn about how the research teams work together, design their research, tools that are needed and how they live and work in an extreme environment.
Objective
Students will be able to:
1. Understand how scientific research is conducted in an extreme environment
Working in groups, students will use common materials to create layers of snow and ice representing thousands of years of stratification. Groups will exchange their ice layers and extract core samples to analyze them.
Objective
Notice the phenomenon of stratification.
Notice that layers can tell a story of change over time.
