Air quality is a measure of the pollution level in the air. Polluted air can be caused by many things. There are manmade and natural sources of emissions. 

Background information on ocean circulation.

My NASA Data (MND) recognizes the importance of data literacy, especially in the Earth Sciences because data are the foundation of science.  But what does data literacy look like?

Students track weather over time and create a bar chart to track their data. 

In this activity students will calculate the ratio of the size of the sun to the moon and the distance of the sun and moon from Earth to determine the type of solar eclipse possible.

In this activity students will make observations about the objects, size, distance, and motion of the Sun, Earth, and Moon during a solar eclipse and manipulate slides to show the relationships.

Phytoplankton distribution background information.

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

Students observe seasonal images of Monthly Normalized Difference Vegetation, looking for any changes in vegetation that are occurring throughout the year. They put the images in order based on what they know about seasonal changes.
