The Department of Environmental Science offers Bachelor of Science in Land and Water Resource Management (both Major and Minor). The major focuses on the study of physical, chemical, and biological processes that shape the Earth and the other planets. The interdisciplinary programme introduces students to both the Science of the Earth and its living and nonliving systems.
Upon successful completion, students will be able to –
Human activity is the major force shaping the natural world today. In this current era of Anthropocene, the major challenges for the humankind are environmental in nature. Unprecedented emission of carbon dioxide, economic growth, urbanization since Industrial Revolution in 1760 have left the world at a stage where climate change is the defining issue of the 21st century. In light of this, Environmental Science course embraces a wide variety of topics from different areas of study. The course is specifically designed for students from different and diverse backgrounds who wish to learn about the physical and biological processes that shape our environment. Our biosphere consists of both living and nonliving elements as well as interactions among them. In this course, students get the scope to dig deep into all these processes and try to investigate why a balanced environment is essential for human survival. Therefore, this course has two broad goals. First, explaining basic concepts in ecology in the light of Chemistry and Biology. Second, applying these concepts to understand some of the critical environmental problems our world is facing today.
Matter and energy. Physical quantities and units. Working with units of concentrations: mg/L, molarity, ppm, etc. Modern concept of the structure of atom. Periodic table of elements. Concept of chemical bonds. Concept of chemical reactions. Concept of mole and stoichiometry of reactions. Gas laws. Modern concepts of acids and bases. Ionic product of water and concept of pH and buffer. Organic chemistry: aliphatic hydrocarbons and aromatic hydrocarbons.

Everything we hear, see, smell, taste and touch involves chemistry and chemicals (matter). Chemistry has widespread implications in everyday life. It is therefore essential to know about chemistry at some level to understand the world around us. CHE 102 course tends to provide students the basic concepts and applications of Chemistry in our daily lives. In this course students will learns how chemistry has developed through the centuries to become one of the fundamental sciences and how it has impacted and propelled the development of human civilization, lifestyle and culture through the ages. This course is designed for students who had little or no background in Chemistry.
