This activity will help students better understand and practice estimating percent cloud cover.

In this lesson, students will explore the effect of aerosols on sky color and visibility by using an interactive virtual model. 

Students will analyze and interpret maps of the average net atmospheric radiation to compare the flow of energy from the Sun toward Earth in different months and for cloudy versus clear days. Students will draw conclusions and support them with evidence.

Explore and connect to the GLOBE Air Quality protocol bundle. 

My NASA Data has recently released several new resources, StoryMaps, for use in educational settings.

Explore and connect to the GLOBE Weather protocol bundle. 

Explore and connect to the GLOBE Urban protocol bundle. 

This resource helps to identify and access GLOBE protocols and hands-on learning activities that complement the Air Quality phenomenon.

Selected GLOBE protocols and learning activities which support some aspect of the investigation of scale, proportion and quantity are outlined.

Students learn how to estimate the "energy efficiency" of photosynthesis, or the amount of energy that plants absorb for any given location on Earth. This is the ratio of the amount of energy stored to the amount of light energy absorbed and is used to evaluate and model photosynthesis efficiency.
