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.
By rolling a die, students will simulate a molecule of carbon’s movement with in the carbon cycle. This is a fun, active way to introduce students to the carbon cycle and/or to review the cycle and identify carbon sinks and sources.
Students experience the carbon cycle as CO2 molecules or as stored carbon and travel the path of
This lesson answers the question: How does ice floating on the ocean act as it melts?
Objective
* Students will learn about temperature, salinity and their effect on density.
* Students will learn that ocean currents are caused by differences in densities as a result of temperature and salinity. These differences allow ocean currents to circulate water
The Dry Valleys region in Antarctica is known as the coldest, windiest, driest place on Earth. Beacon Valley is famous for its katabatic winds which can routinely knock fit adults and PolarTREC teachers to the ground. This lesson was created by PolarTREC teacher Jacquelyn Hams who experienced the cold and the full force of the winds in 2008
