Description of Course Course Title:

Chemistry I, Applied - # 403 Description:

This course is a program designed to popularize chemistry and to reach out to the large audience of students with a limited science and mathematics background. Students gain an understanding of the unifying concepts that relate to various areas of organic chemistry, inorganic chemistry, biochemistry, nuclear and physical chemistry and environmental chemistry. The relationship chemistry has to our everyday lives will be stressed.

Goals:

• Identify the principles of chemistry which play a relevant part of their everyday lives. • Learn concepts by performing exploration-based activities. • Use problem-solving techniques, which can be applied to biological, environmental, and

consumer situations. • Develop safety attitudes and skills related to safe handling of chemicals and equipment.
