Forces of Nature

Get up close and personal to erupting volcanoes, devastating earthquakes, and powerful storms as scientists travel the world trying to understand what causes these dangerous natural events. Risking their lives for scientific discovery, these experts forge their way through volcanic flows, along treacherous fault lines, and in cars heading straight toward a raging twister.

Forces of Nature is a National Geographic production.

Forces of Nature is recommended for ages 6 and up. Teachers interested in bringing a school group should consult the Tennessee Curriculum standards information listed below.

Forces of Nature currently available for school groups. To book a group reservation, call (615) 862-5177 at least two weeks in advance.

TN State Science Standards

Conceptual Strands

  • EMBEDDED INQUIRYUnderstandings about scientific inquiry and the ability to conduct inquiry are essential for living in the 21st century.
    Guiding Question: What tools, skills, knowledge, and dispositions are needed to conduct scientific inquiry?
  • STANDARD 7 - THE EARTH Conceptual Strand 7: Major geologic events that occur over eons or brief moments in time continually shape and reshape the surface of the Earth, resulting in continuous global change.
  • STANDARD 8 - THE ATMOSPHERE Conceptual Strand 8: The earth is surrounded by an active atmosphere and an energy system that controls the distribution [of] life, local weather, climate, and global temperature.

Grade Level Expectations (GLE)

Math Standards: STANDARD 5: DATA, PROBABILITY AND STATISTICS

Objectives

  1. Name one active volcano.
  2. Name at least one active fault zone in North America.
  3. Describe conditions that cause many thunderstorms in the Midwest.

Pre-visit Activities

  1. Discuss the structure of the Earth and the factors that shape landmasses both above and below the surface: plate tectonics, volcanoes, wind and water erosion, drought, human activity, etc.
  2. Examine the geologic processes that create volcanoes and the difference between Hawaiian volcanoes and Mount St. Helens.
  3. Have students research the plates that make up and surround North America and how those plates are moving relative to one another.
  4. Discover how many tornadoes occur each year in Tennessee and other southern states and when they typically occur. Research “tornado alley” and how weather patterns increase the chance of severe storms and tornadoes.

Post-visit Activities

  1. Grade-specific activities are available from the National Geographic Forces of Nature web site
  2. The March 2011 earthquake in Japan ranks near the top of historic earthquakes. Examine where earthquakes have occurred around the world and their resulting impact.
  3. Have students research the New Madrid quakes of 1811-12 and the fault zone area of west Tennessee and southeast Missouri. What are the predictions for future quakes there?
  4. Have students assess their hometown for all types of disasters. What can one expect and how often?
  5. Forces of Nature discusses how we should be prepared for disasters. Have students create emergency plans and kits for home and school. Consider scenarios such as: what would you do if there was no electricity for two weeks after a storm?
  6. Have students research historic volcanic events. How could a large volcano affect atmosphere, weather and climate around the globe?
