Understanding the principle of experiments and the obtained meanings of the properties by the experiments is essential in material science and engineering. The learning of fundamental skills of chemical and physical measurement operation is required for the correct and safe experiments. In this experiment course, the following topics will be covered: understanding of fundamental photophysical characteristics of absorption, fluorescence and phosphorescence for organic molecules; leaning basic techniques for organic synthesis and characterization methods of organic molecules for structural determination; basic skills for suspension polymerization, characterization technique for ion exchange resin and basic skills for kinetic study.
The aims of this course are to make students get the basics for organic and polymeric materials through the learning of experimental operations, principles and comparison between the theoretical and experimental data, in order to improve their skills and understandings from the viewpoints of general education covering the wide area from the basics to the advanced research of science and engineering.
Additionally, the number of students may be restricted due to the limitation of a laboratory space. The learning quarters and orders could be also changed. Students can learn whole themes in Experiments of Organic and Polymeric Materials I, II and III in a different order, by taking all courses of Experiments of Organic and Polymeric Materials at 1st, 3rd and 4th quarters.
By the end of this course, students will be able to:
1. acquire fundamental skills of chemical and physical measurement operations,
2. understand the chemical reactions and analysis,
3. understand the meanings of measured properties and their principles,
4. understand the relation between the conditions of sample preparation and their properties,
5. understand the experimental methods, data analysis and discussion based on obtained data, and learning the basics for more advanced experiments.

To enhance effective learning, students are encouraged to spend approximately 50 minutes preparing for class and another 50 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
Reference books, course materials, etc.
Reference books, course materials, etc.
Full attendance and completion of all experiments are compulsory. Assessment is based on the quality of the written reports and on the status of submission thereof. Students may fail this course if they repeatedly come late to classes or often delay the submission of reports.
No prerequisites are necessary, but enrollment in the related courses is desirable.
