The Mountain Blows its Top

Students will observe fault movements on a model of the earth's surface.

The Slope of Land in Your Community

The slope of the land and the materials under ground must be considered when planning how to build on the land in a community to lessen landslide risk. Changing the slope of the land (or even the amount of vegetation on a slope) can have dangerous consequences. This activity will introduce you into thinking critically about the land in your area!

Tropical Atlantic Aerosols

In this 50-minute activity, you can use NASA satellite data to find out where there are the greatest concentrations of aerosols over the course of a year in the tropical Atlantic region, and where these aerosols come from.

Watch Out for Landslides

Landslides not only are dangerous — causing on average more than 25 deaths and over $1 billion in damages a year — but are also widespread, occurring in all 50 states. Compounding the hazards, these natural disasters often occur along with other similar natural phenomena, such as floods or earthquakes. To minimize risk, the slope of land and materials underground must be considered when planning how to build in a community. Altering the slope of land, or even the amount of vegetation on a slope, can have dangerous consequences.

Water Filtration

Each group will design a water filtration system and present to the class, why they picked their design.

Where Growth Meets Growth

Learn to identify fire risk factors for a property located near a wildland area.

Your Own El Nino

Every two to seven years, trade-winds in the Pacific Ocean slow down or reverse their direction — no one is sure why. But when the trade winds slow down, everything changes. Water temperatures become warmer in the eastern Pacific and colder in the west. Nutrient upwelling slows, and fish populations become much smaller along the Pacific coast of South America. Rainfall follows the warmer water, causing flooding in Peru and drought in Indonesia and Australia. Because these changes can be highly destructive, advance warning of El Niño’s approach is important for emergency preparation. NOAA satellites are constantly collecting information on sea surface temperatures around the globe. NOAA also operates a network of buoys that measure temperature, currents, and winds in the tropical Pacific Ocean.

Your Own Greenhouse

Climate scientists around the world study greenhouse gases and the ways they affect global climate. By making your own small greenhouse in this activity, you can recreate the greenhouse effect and measure its effect on temperature.
