CLIL (Content and Language Integrated Learning) is one of the methodologies available to teachers holding English classes to help children acquire a second language. In CLIL, children learn a second language through subject content. The method is well known in European countries, but in Japan there have not been many practical reports on it. In this study, we constructed CLIL-remodeled science classes (SLIL classes: Science and Language Integrated Learning classes), which are not treated as language educational approaches, but as Science and English dual-focused approaches, fundamentally Science cognition based. This paper also reports on two forecasting SLIL practices, one on volcanic ash and one on the hardness of minerals, which we conducted in an elementary school.

In this paper we introduce the principle of a three-variable linear nomogram and describe how to make a nomogram. Using this item, the magnitude of an earthquake is easily calculated from seismograms. Our nomogram-creation process, which uses Microsoft Excel 2016, is described in detail. A nomogram can be used not only for magnitude estimation, but also for learning about the logarithmic characteristics of earthquakes. Our process enhances the availability and possibilities of nomograms in educational seismology. The applications of nomograms for other fields of geoscience will be a future challenge.
