In this activity, students explore three indicators of drought are: soil moisture, lack of precipitation, and decreased streamflows. Students investigate each of these parameters develop a sense for the effects of drought on land.

In this interactive, students will explore safe methods for viewing the Sun at home or in the classroom, including using solar eclipse glasses and a pinhole projector. The interactive includes a video that explains how the projector works and how to build one.

What is the hydrosphere and why is it important?

Explore and connect to the GLOBE Water Cycle protocol bundle. 

Explore and connect to the GLOBE Water Quality protocol bundle. 

Explore and connect to the GLOBE Soils protocol bundle. 

GLOBE protocols and learning activities that complement the Soil Moisture phenomenon through hands-on investigations are detailed. 

The Solar Eclipse Implementation Sequence provides a series of lesson plans for students to learn about solar eclipses.

This hands-on activity is the construction of an extended coverage area of eclipse glasses to provide extra protection for safely viewing a solar eclipse. This makes it harder to look outside the lenses on the eclipse glasses.

In this activity, students will model the geometry of solar eclipses using quarters to represent the Sun and Moon (not to scale).
