Students design and construct devices to trap insects that are present in the area around the school. The objective is to ask the right design questions and conduct the right tests to determine if the traps work .
Students learn what causes earthquakes, how we measure and locate them, and their effects and consequences. Through the online Earthquakes Living Lab, student pairs explore various types of seismic waves and the differences between shear waves and compressional waves. They conduct research using the portion of the living lab that focuses primarily on the instruments, methods and data used to measure and locate earthquakes. Using real-time U.S. Geological Survey (USGS) data accessed through the living lab interface, students locate where earthquakes are occurring and how frequently. Students propose questions and analyze the real-world seismic data to find answers and form conclusions. They are asked to think critically about why earthquakes occur and how knowledge about earthquakes can be helpful to engineers. A worksheet serves as a student guide for the activity.
Students learn how engineers characterize earthquakes through seismic data. Then, acting as engineers, they use real-world seismograph data and a tutorial/simulation accessed through the Earthquakes Living Lab to locate earthquake epicenters via triangulation and determine earthquake magnitudes. Student pairs examine seismic waves, S waves and P waves recorded on seismograms, measuring the key S-P interval. Students then determine the maximum S wave amplitudes in order to determine earthquake magnitude, a measure of the amount of energy released. Students consider how engineers might use and implement seismic data in their design work. A worksheet serves as a student guide for the activity.
Students learn the two main methods to measure earthquakes, the Richter Scale and the Mercalli Scale. They make a model of a seismograph a measuring device that records an earthquake on a seismogram. Students also investigate which structural designs are most likely to survive an earthquake. And, they illustrate an informational guide to the Mercalli Scale.
Locating the epicenter of an earthquake- basic intro
Students learn about the types of seismic waves produced by earthquakes and how they move the Earth. The dangers of earthquakes are presented as well as the necessity for engineers to design structures for earthquake-prone areas that are able to withstand the forces of seismic waves. Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings.
