In this lesson, students will use NASA satellite measurements of atmospheric pressure to learn that pressure decreases with height in the atmosphere. Full description.

Solar radiation (light) strikes Earth's surface throughout the daylight hours. Radiation (heat or infrared) also leaves the Earth during daylight and at night. Averaged over time and space, these downward and upward energy fluxes are equal. If they were not, our planet would gradually heat up or gradually cool down. But the surface of our planet is not simply a mirror for radiation. Some of the incoming ... Full description.

Climate is the long-term weather conditions for a region, generally determined by 30 or more years of records. Climate zones can be defined using parameters such as temperature and rainfall. In this lesson, students will make climatic diagrams called climographs which will relate weather and climate for a particular location. Monthly average values of weather data such as temperature and precipitation ... Full description.

In developing models for climate change and weather prediction, the measurements of surface and near-surface temperature are an important factor in the modeling process. As the Sun heats the Earth's surface, the atmosphere is warmed from below by the processes of conduction and convection from the surface. However, near-surface air temperature (approximately 10 meters above the surface) is often different ... Full description.

Weather involves the daily fluctuations in temperature, humidity, clouds, winds, etc. By contrast, climate is the long term weather patterns in a region. Therefore, to assess changes in climate, one has to look at average changes over long periods of time. Students will use long wave radiation data to determine whether the climate has changed in Portland, Oregon over a 20 year time span. They will ... Full description.

Clouds are a collection of water droplets and small ice crystals that are suspended in an atmosphere. Clouds form when moisture rises, cools, and changes to water or ice. It is important to take into consideration exactly how clouds affect the world around us. Clouds are an important determining factor in climate in any region around the globe. In this lesson, students will plot and analyze data for ... Full description.

Earth's albedo is the fraction of incoming radiation (sunlight) that is reflected into space. The Earth has an average albedo, which describes how much sunlight is reflected on average for the whole planet and the whole year. The Earth also has a local albedo, which determines how much of the Sun's light is reflected from a particular place at a particular time. The local albedo depends on the particular ...

The Darby Creek watershed encompasses an area of approximately 550 square miles in central Ohio. The Big and Little Darby Creeks are well known for their vast diversity and abundance of aquatic and terrestrial plants and animals. They are home to eighty-six species of fish, five of which are endangered. Forty-one species of freshwater mollusks live in these waters, eight of which are on the Ohio endangered ... Full description.

There are various local and regional climates on the Earth's surface. While the overall climate of the Earth is often the focus of research and discussion, individual local climates are important to consider when thinking of indigenous plants and animals. In this lesson, students will choose two locations, preferably in different climate zones, and compare real NASA satellite data for those two locations. ... Full description.

Students will use NASA Satellite data to analyze and understand ways of studying photosynthesis from space. They will assume the role of a park ranger at Shenandoah National Park and determine when the plants and trees at their top efficiency by analyzing when the plants are absorbing a majority of the light hitting them (within the photosynthetic range.)
