Abstract:
Elementary seismology notions are studied by high school students, both as direct applications for mechanical waves and through other various optional courses. The domain is a current one because earthquakes are natural phenomena that are part of life. With a major impact on our lives, these events are sometimes misread and the information provided by mass media is often insufficiently explained from the scientific perspective. In this paper, a scientific investigation method based on conceptual maps that can be successfully applied in Seismology studies is presented. Structurally, we have a main conceptual map from which some other various elements that are adding more information go, such as new concepts, examples and applications. The main conceptual map introduces the basic notions as the sources and causes of the earthquake occurrence, their parameters, means of study and the earthquake inquiry usefulness. Connections towards three other conceptual maps can be found. These maps explain some aspects such as seismic waves (types, characteristics, propagation), seismometers (types and operation mode), and Earth's internal structure. Two interactive applications that allow students to establish the epicenter location and the earthquake magnitude can be found as well. Animations and illustrations that exemplify the studied phenomena as seismic waves propagation, earthquake effects, precaution measures etc. are also attached to the maps. In the creation process of all the materials, some open-source and free computer programs have been used: Cmap Tools for building the conceptual maps, Geogebra for interactive applications, Tupi and Kdenlive and Whiteboard Animation technique for animations, Inkscape for images. The study is built in a manner that allows its use both during face to face, as well as online activities. All the resources can be distributed in the cloud and the programs can run on any kind of device and under any operating system.
