Course description and aims
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: application of finite difference method for numerical analysis of heat transfer, comparative analysis of numerical results with direct temperature measurements and heat transfer visualization using an infrared camera; measure the characteristics of PLLA with differential scanning calorimetry (DSC), wide-angle X-ray diffraction (WAXD) and dynamic mechanical analysis (DMA), understand the principles of those measurements, discuss the relationship between the micro-structure and thermal and mechanical (temperature- and frequency-dependence) characteristics; understanding of fundamental photophysical characteristics of absorption, fluorescence and phosphorescence for organic molecules.
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.
Student learning outcomes
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.

Class flow
Students work in teams throughout this course and conduct a series of experimental themes. 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. Written reports must be submitted by designated dates. Students must read the experiment text before the start of each experiment to ensure safety and smooth running.

Out-of-Class Study Time (Preparation and Review)
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.
Textbook(s)
Course texts are provided during class.
