The Mountain Blows its Top Activity Source: USGS Learning Web Lesson Plans Background A volcano is a vent in the surface of the Earth through which magma and gasses erupt. Volcanic eruptions are among the Earth’s most powerful and destructive forces, but volcanoes are also creative. Volcanoes have also shaped the Earth’s landscape, as many of our mountains, islands, and plains have been built by volcanic eruptions. Mount St. Helens was one of the most powerful volcanic eruptions in recent memory. [Read More]

The Slope of Land in Your Community Activity Source: Adapted from the American Geosciences Institute’s EarthComm: Understanding your Environment Background Landslides constitute a major geologic hazard. They are widespread, occurring in all 50 states, and cause $1-2 billion in damages and more than 25 fatalities on average each year. Landslides commonly occur with other major natural disasters, such as earthquakes and floods (USGS Learning Web). 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. [Read More]

Tropical Atlantic Aerosols Activity Source: Adapted with permission by National Aeronautics and Space Administration. MY NASA DATA (http://mynasadata.larc.nasa.gov) makes NASA Earth science data accessible to K-12 teachers and students, as well as citizen scientists. You can use the data and lessons with your existing science curriculum. The investigations will help you to practice science inquiry and math or technology skills using real measurements of Earth system variables and processes. MY NASA DATA microsets are created using data from NASA Earth science satellite missions. [Read More]

Watch Out for Landslides Activity Source: Adapted with permission by the Association of American State Geologists, from AGI’s Earth System Science in Your Community. Background 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. [Read More]

Water Filtration Activity Source: Nebraska Earth Systems Education Network, School of Natural Resources, By Kimberly Flessner Objective: Each group will design a water filtration system and present to the class why they picked their design. Materials: 1 or 2 2-liter bottles scissors 1 250ml beaker filtration materials (examples: soil, gravel, potting soil, cotton balls, scrap material, charcoal, sand, woodchips, Styrofoam packing, charcoal briquettes) screening rubber bands Bunsen burner or heat source for evaporation “polluted water” (tap water with salt, food coloring, sand, and dish soap added to it) Procedure: Each group of 2 or 3 need to design an idea for a filtration system.

Where Growth Meets Growth Activity Source: DiscoverySchool.com Credit: Susan Hurstcalderone, science and resource teacher, Blessed Sacrament School, Washington, D.C. Objective To identify fire risk factors for a property located near a wildland area. Materials copy of Where Growth Meets Growth student handout colored pencils Procedure One of the issues surrounding wildland fires involves areas where uncontrolled urban growth meets uncontrolled vegetative growth. People who live in these areas should take extra precautions to limit the effects of any nearby wildland fire that might occur. [Read More]

Why Settle at Mesa Verde Traditional geologic maps — sometimes crisscrossed with lines, blotted with colors, and marked with strike and dip symbols — have been used for at least 200 years to depict the geologic makeup of the Earth. Consider the map and other images of Mesa Verde National Park in Colorado shown here. Each provides a different perspective on the geologic makeup of the area. President Theodore Roosevelt created the 52,485-acre Mesa Verde National Park in 1906 to recognize and protect sites of natural and historical significance. [Read More]

Your Own El Nino Activity Source: Adapted with permission by the National Weather Service from Discover Your World with NOAA: An Activity Book Background El Niño storms have taken thousands of lives and caused billions of dollars in damage in recent decades. Where do these storms come from? Every two to seven years, trade-winds in the Pacific Ocean slow down or reverse their direction — no one is sure why. [Read More]

Your Own Greenhouse Activity Source: ARM and the U.S. Department of Energy. Adapted with permission. As far back as ancient Greek and Roman times, people built structures that created an indoor environment suited to growing plants throughout the year. This enabled the gardener to establish a measure of control over growing conditions and extend the growth period into the colder seasons of the year. In this manner, the gardener was better able to provide fresh fruits and vegetables when needed. [Read More]
