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 will play a fun board game that teaches about the sources and types of some air pollutants, and how they affect the health of both people and the environment. Students will learn that not all pollutants are greenhouse gases. This game can be a lead-in for a discussion about climate change and what people can
