Integrated Arts and Sciences
(Abilities and Skills)
・The ability and skills to collect and analyze necessary literature or data among various sources of information on individual academic disciplines.
・The ability and skills to specify necessary theories and methods for consideration of issues.
・The abilities and skills to summarize one's own research in reports or academic papers, and to deliver presentations at a seminar or research meetings, and to answer questions.
(Comprehensive Abilities)
・The ability to conduct research proactively by combining knowledge,  understanding, and skills for the tasks, based on flexible creativity and imagination. 
Class Objectives
/Class Outline
To learn basic knowledge and experimental techniques required for analyses and interpretation of natural environments through laboratory and field studies. 
Class Schedule ・Analysis of geological data: lineament, fold structure, electron microscopy and energy dispersive X-ray analysis. (1-3: Hirayama)

・Colloid and Interface Science (Villeneuve and Iwamoto : 4-9): June 14, 20, 21, 27, 28, July 4
Colloidal and capillary interactions exist everywhere in the natural environment and human activity, including fog, aerosol, condensation, soil aggregate structures, sandbar formation, food, and industrial processes. Students will conduct experiments to understand colloids and interfaces.
Lesson 4 Size distribution of aerosol [statistics, stability of colloids, Kelvin's equation]
Lesson 5 Synthesis and coagulation of Fe(OH)3 colloid [stability of colloids, DLVO theory]
Lesson 6 Chemical sunset [light scattering by colloidal particles, kinetics]
Lesson 7, 8 Surface tension measurement of surfactant solution [solution chemistry, phase rule, thermodynamics of a capillary system, monolayer film and micelle]
Lesson 9 Data analysis

・Principle methods in Biodiversity (Yamada, Hosaka, Nakabayashi: 10-13): July 5, 11, 12, 19 (In case of rain, it may be held on Saturday, 20th and Sunday, 21st.)
You will learn field and analytical methods for quantitative evaluations of biodiversity in forest ecosystems. Also, you will learn how to evaluate the diversity of plants, insects, and mammals, and analyze the interactions among them.

・Properties of Polymers (Watanabe: 14, 15): July 25, 26
You will learn the unique properties of polymers (molecules of large molecular weight), such as glass transition and viscoelasticity, which differ from low molecular weight substances through experiments. 
Handouts will be provided by each instructor.
