No matter if you are an elementary, middle, or high school science teacher, we bet that you observe and investigate air temperatures or (their effects) with your students.  Changing air temperatures are cyclical and predictable, but also are rising beyond the normal range due to a variety of fact

In some parts of the world sea levels are increasing, while decreasing in others, and even remain relatively flat in a few places; for more than 20 years, NASA has been tracking the global surface topography of the ocean to understand the important role it plays in our daily lives. 

Snow cover and ice extent are monitored by satellite instruments measuring the reflectance of Earth's surface in various wavelengths every day. Snow and ice have a recognizable pattern of reflectance, so the satellite data can be processed to show where snow and ice are present. 

In this activity, you will use satellite images from the NASA Landsat team to quantify changes in glacier cover over time. This lesson utilizes change pair images of Bear Glacier in Kenai Fjords National Park, located on the southeastern portion of Alaska’s Kenai (pronounced: Key-nigh) Peninsula,

We often take the Biosphere for granted and as the climate changes, plant species and ecosystems respond by adapting, migrating or reducing their population.  Why is this important?  The plants of the Biosphere feed us, clothe us, absorb carbon dioxide, provide us with oxygen,

The ocean's surface is not level, and sea levels change in response to changes in chemistry and temperature. Sophisticated satellite measurements are required for scientists to document current sea level rise.
