Background on changing albedo values.

What is the hydrosphere and why is it important?

Explore and connect to the GLOBE Urban protocol bundle. 

Discover how GLOBE supports hands-on science for locally relevant learning which is also put into a global perspective.

Students watch a video introducing the concept of albedo and answer questions.

Students watch a video explaining albedo and its impact on Earth. The video shows visualizations of albedo across Earth and how it can change. Students will interpret the images in the video and answer questions about albedo.

Find GLOBE resources which are connected to My NASA Data cryosphere phenomena. These include campaigns, eTraining and how to find related student projects.

Through guided inquiry, students will identify interactions of the four major scientific spheres on Earth: biosphere, atmosphere, hydrosphere and geosphere. They will then identify how these systems are represented and interact in their classroom aquarium.

In this activity, students make a claim about the cause of ocean currents and then develop a model to explain the role of temperature and density in deep ocean currents.  This lesson is modified from "Visit to an Ocean Planet" Caltech and NASA/Jet Propulsion Laboratory.

The Earth's system is characterized by the interaction of processes that take place on molecular (very small) and planetary (very large) spatial scales, as well as on short and long time scales. Before scientists may begin their work with these data, it is important that they understand what the data are.
