Operation Weather Station

Tree rings from North America give a continuous history of El Nino intensity over the last 1,100 years. Scholars learn how scientists use tree rings to create timelines demonstrating variations in weather patterns. The cumulative...

Which is worse — drought or flooding? Neither is helpful to the environment, and both are increasing due to climate change. The 16th lesson in a series of 21 covers the average precipitation trends for two different climates within the...

Desert regions are hotter for multiple reasons; the lack of vegetation causes the sun's heat to go straight into the surface and the lack of moisture means none of the heat is being transferred into evaporation. This concept, and other...

Currently, only 2.1% of global warming is felt on continents, while over 93% is felt in the oceans. The fourth lesson in the series of 21 on global warming is composed of three activities that build off one another. In the first...

When earth scientists or mini meteorologists are learning about wind, they can participate in an engineering activity in which they will design and construct an anemometer. A thorough overview of different types of anemometers is...

How does gravity affect the life cycle of a butterfly? Learn first-hand what types of investigations astronauts perform in space by following along with one of NASA's experiments. Create butterfly habitats in the classroom with specific...

It's an ocean rescue mission! Groups must find a pilot downed off the coast of the Chesapeake Bay. Rescuers must determine the distance needed to travel as well as the heading to get to the pilot's last known position. Taking into...

Some of the CO2 emitted by burning fossil fuels is removed from the atmosphere by natural sinks, such as the ocean. The fifth engaging lesson in the series of 21 examines the CO2 data from three very different locations. It then makes a...

Students describe how weather forecasting has evolved.  In this forecasting lesson students study the different types and ways that people forecast weather. 

Investigate weather facts and figures to determine what has caused particular climate conditions. Research air pressure, temperature, wind, and humidity. Conduct online research to determine what air pressure, wind, temperature, and...
