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 lesson students research scientific field expeditions and learn what it is like working in the field. Students are able to ask questions of the research team as part of their project. Students then share what they have learned with their classmates.
Objective
1. Students understand what really goes on in the field during a scientific study.
2
An important science skill that needs to be developed is asking significant questions that advance knowledge. This activity helps students to understand the difference between significant and trivial questions.
Objective
Students should be able to distinguish between significant questions that advance knowledge and trivial questions.
Procedure
1. Have the students define significant question and trivial questions in a
