SummaryStudents are introduced to our planet's structure and its dynamic system of natural forces through an examination of the natural hazards of earthquakes, volcanoes, landslides, tsunamis, floods and tornados, as well as avalanches, fires, hurricanes and thunderstorms. They see how these natural events become disasters when they impact people, and how engineers help to make people safe from them. Students begin by learning about the structure of the Earth; they create clay models showing the Earth's layers, see a continental drift demo, calculate drift over time, and make fault models. They learn how earthquakes happen; they investigate the integrity of structural designs using model seismographs. Using toothpicks and mini-marshmallows, they create and test structures in a simulated earthquake on a tray of Jell-O. Students learn about the causes, composition and types of volcanoes, and watch and measure a class mock eruption demo, observing the phases that change a mountain's shape. Students learn that the different types of landslides are all are the result of gravity, friction and the materials involved. Using a small-scale model of a debris chute, they explore how landslides start in response to variables in material, slope and water content. Students learn about tsunamis, discovering what causes them and makes them so dangerous. Using a table-top-sized tsunami generator, they test how model structures of different material types fare in devastating waves. Students learn about the causes of floods, their benefits and potential for disaster. Using riverbed models made of clay in baking pans, students simulate the impact of different river volumes, floodplain terrain and levee designs in experimental trials. They learn about the basic characteristics, damage and occurrence of tornadoes, examining them closely by creating water vortices in soda bottles. They complete mock engineering analyses of tornado damage, analyze and graph US tornado damage data, and draw and present structure designs intended to withstand high winds.
Engineers learn about our planet so that humans can exist with and survive its powerful natural forces. Engineers must be aware of natural hazards in order to prevent or minimize their harmful effects on people and property. By creating improved techniques and materials, engineers make sure the structures we rely upon are built strong enough to reduce human injuries and casualties from the tremendous natural forces of wind, snow, water, fire and moving earth. While most natural hazards cannot be prevented, engineers do their best to create data gathering, monitoring, measuring, prediction and warning equipment, tools and models to protect human populations. Engineers use their science and math skills to build instruments and computer programs that can detect gases, changes in the shape of volcanoes, monitor underground movement, and estimate storm locations and severity. Data is collected by cameras, seismometers, GPS, pressure sensors, radar and satellites. Other helpful technologies include avalanche beacons and airbags, lightning rods, building shock absorbers and sliders, and warning sirens. Engineers work with scientists to determine locations at which dangers exist, how to minimize risks, and how to prevent the actions of people from creating catastrophes. Engineers also design test facilities to simulate and study hazard characteristics and model scenarios with computer simulations. Engineers also analyze and learn from past failures as a way to continue to improve structural designs, advance warning systems and emergency procedures for human safety. As engineers create devices that detect natural hazards, build structures to withstand them, and invent devices to study them, they use the process of gathering and analyzing data to better understand problems and formulate solutions.
