The striped magnetic anomalies over the mid-ocean ridges play an important role at the emergence of the plate tectonics
from the classical continental drift theory. The so-called ”The Tape-Recorder Model” developed by Vine and Mathews(1963) isessential to study this process in a high-school class room. However only text-based resources are used to study for this theme.
The students do not learn the theory and development process with firm reality or motivation. In this regard, we developed ananalog model showing this striped magnetic anomalies in our class room. The model consists of a thick foamed styrol plate andiron nails which have been magnetized using a permanent magnet. The plate is a mimic of ocean floor and covered partly withcolored tapes symmetrically showing stripes. The normal magnetized nails and reversed nails are stuck on the grids of the plate
symmetrically across the center respectively. The measurement is carried out on a acrylic transparent plate above the foamed
styrol plate which symbolize sea surface and sea floor. A magnetic sensor (Gauss-mater) is transversed over the model slowly
and the total magnetic strength are measured at real time showing a periodic change. So, the students can be experienced themeasurment on the ship and can comprehend easily the meanings of this measurment and the relation with the mechanism of”The Tape-Recorder Model”. The cost of Gauss-meter is high expensive, so we tried to use a smart-phone as an alternative andfound that thier magnetic sensor and the free application are sufficient enough and quite useful for this type of measurement. Atthe conference, we will present an analysis of this model and make a demonstration of magnetic survey using our model.

We report the results and educational effectiveness of our volcanology classes in the elemental schools in Katsuyama, Fukui.
The volcanology class is a part of the outreach activity in Dinosaur Valley Fukui Katsuyama Geopark, and is designed for thepurpose of disseminating knowledge of volcanoes and volcanic products in Katsuyama region. Although there is no active volcano in Fukui prefecture, several Quaternary volcanoes (1 to 0.7 Ma) are existed in Katsuyama region. These volcanic products
formed a large part of the basement in this region. The largest ski site in Fukui (SKIJAM Katsuyama) harnesses the slope oflava flow morphology of the youngest volcano (Hoonjisan) in this region. These facts indicate that people in Katsuyama region
lives on the benefits of volcanoes, however, the relationship between volcanoes and the land formation in Katsuyama region is
not well understood by local residents. Thus we aim to give elementary school students a deeper understanding of volcano andthe land formation in Katsuyama region through our volcanology class. In the class, we demonstrated an experiment of lava
formation by using portable clay cooking stove (Shitaoka et al., 2011). The students observed lava forming process, and measured the temperature of the produced fluid lava by using an infrared radiation thermometer during the experiment. In addition,
the students observed flowing lava on the slope of sandpile, and studied the formation of lava flow morphology. The results ofquestionnaires after the volcanology class indicate that the students understood the formation of lava flow morphology and thebasement volcanic products of SKIJAM Katsuyama, and also show the improvement of their interest to the relationship between
volcanoes and the land formation in Katsuyama region.

The intention of this study is to consider the efficiency of a multidisciplinary approach of learning from the perspective ofgeology and geography. The common word ”GEO” implies its commonness and many geology and geography teachers areaware of it, but just vaguely. It is time to reconsider the relation between both learning concretely, since the global environmental
change has increased its complexity and needs a practical interdisciplinary approach for the real solution. In particular in Japan,
the earthquake in 2011 also stimulated us to reconsider our perspective on earth. Such actual problems should be addressed bywhole earth perspective and through an interdisciplinary approach. These points are intensively discussed in context of futureearth. As a school subject concerned with earth and global problems, geology and geography can contribute to it.
We planned and implemented a one-hour class with multidisciplinary approach of geology and geography for 52 11th-gradestudents in a private high school in Tokyo. The issue is Fossa Magna, geological feature located in central Japan, treated at firstfrom geological aspects such as development of Japan islands, active fault line and thickness of sediment rock. Successively
into geographical aspect such as geo-tourism in Geopark, mining limestone and developing cement industry. The questionnaireof students review shows 96% of students ”understand the difference of the 2 subjective perspectives” and ”recognize the significance of the multidisciplinary approach.” Almost half of them agree that ”multidisciplinary learning is efficient for betterunderstanding.”
Earth-scientific explanation from the perspective of geology is to geographies advantage to learn scientific physical conditionfor human activity. As for geology, the relation between geological features and human activity treated by geography gives
feedback to geology to remind the significance of learning geology.
For further advance of multidisciplinary approach, besides revising learning material, the potential of the cooperation of 2
geo-subjects should be discussed at curricula level.

The role of the teacher in ordinary high school who worked in SSH high schoolKAWAKATSU, Kazuya1∗

Hyogo Prefectural Nishiwaki senior high school

1.Introduction
I worked in Hyogo Prefectural Kakogawa Higashi High School that is SSH designated school, during 10 years until 2013 fiscalyear. I focused on geoscience education and offered the earth science course regardless of the humanities and science. The EarthScience Club I was teaching got first prize in the Geological Society of Japan and the Physical Society of Japan. In addition, theEarth Science Club got many high reputations, including the Minister of Education, Culture, Sports Award. The guidance of me
was also evaluated, and I was awarded the like of Education, Culture, Sports, Science Minister excellent faculty awards, Noyoriscience Award, Physical Society Lifetime Achievement Award, and Kanagawa University Excellence Leadership Award.
I transferred to this year Prefectural Nishiwaki Senior High School, became the adviser of Earth Science Club and BiologicalClub. I was entrusted with the activation of the entire science education including the students of the science education course.
I think every day, what is the role being sought in myself, and if there is any way to fulfill it in annual budget of about one
twentieth of SSH schools. What is required for teachers who experienced the SSH high school? Between I has been working inSSH high school, I had teachers consciousness noticed that easy to change imperceptibly from ”implementation of the researchand development of high-level science and mathematics education” that is philosophy of installation of SSH high schools, to”studies that cannot be only in SSH schools”. Activities of SSH that are carried out with a lot of taxes, have tried the competenceof its budget enforce teacher. The study theme of me while working in SSH high school was how to can be study originality andpriority researches, and how to grow the imaginations without using a special analysis device. The experience, knowledge andpersonal connections obtained in SSH high school, has been utilized in the current working school.
2.Current specific educational activities of
Nishiwaki Senior High School located in the mountainous region of the south area of Hyogo Prefecture. The school consists ofinfantry 7 classes and an information science 1 class per grade, and about 70 students go onto the National University. Students
are laid-back and very serious. Students are timid for a challenge to new things for inexperienced.
I was appointed to this school, and I established the Earth Science Club at the same time. About 30 students participated in thestudies. They study actively on the theme full of originality. I am realizing that the students had been craving a stimulus. They
think by hypothesis deductive method and announce the results in the research papers and posters.
I am teaching students by take advantage of experiences and knowledges and personal connections of SSH high school. And I
take advantage of the research methods that do not use special analysis equipment. The students join many tournaments that thecost is not take because school budget is small. The Earth Science Club has already played nationwide top finishers, in just half ayear for the first time research. The Students are studying in two themes now. (1) clarify the formation process of southern Hyogo
Prefecture, (2) the estimate of movement of the ground based on the cracks around the manholes, and the recommendations ofthe maintenance standards of ground. I am involved in the agency cooperation project that connect the citizens and scientists
with a focus on Kobe University as a core member.

Dpt. of Phys., Tokyo Gakugei Univ., 2 Kagawa Prefectural Sanbonmatsu High School, 3 Hyogo Prefectural Kobe High SchoolA various investigation of sprites, one of frequent observable transient luminous events (TLEs) in the region from mesosphere
to lower ionosphere, has been reported. Sprites are induced by a strong electric field attributed to the neutralization of a large
amount of positive charges at the upper part of thunderstorm when positive cloud-to-ground (CG) lightning occurs. Many papers
have suggested that the complex physics of sprite-induced CG lightning, termed parent CG lightning, causes various morphologies and lifetime of sprites and the time delay of sprite occurrence, which have been some of unsolved issues in the TLEs studies.
In addition, the major issue might be the largely different locations in horizontal between sprites and parent CG lightning, which
often reaches about 50 km. On the other hand, sprites occur just above the luminous center of parent CG lightning according
to satellite observations. It is expected that the luminous center of parent CG lightning over the thunderstorm is equivalent to
the positive charges at the upper part of thunderstorm where the positive CG lightning starts. Few study, however, discusses thehorizontal differences among the sprites, the luminous center of parent CG lightning over the thunderstorm, and the strike pointof the parent CG lightning. Thus, we investigate the differences among them through an optical measurement, assuming that theposition of positive charges at the upper part of thunderstorm is the luminous center of parent CG lightning over the thunderstorm
in cooperation with high-school sprite observation network.
