Fundamental Chemistry Textbook for Senior Secondary School

By Mr Adeshina Tayo Adelani

Chemistry as a science subject Science is an organized body of knowledge gathered through systematic experimentations and philosophical observations. Chemistry can be defined as a branch of science which deals with the study of nature, structure, composition, properties, and uses of all forms of matter and the changes in structure and composition which matter undergoes. Branches of Chemistry The three main branches of chemistry are: Physical chemistry Organic chemistry Inorganic chemistry Physical chemistry deals with the physical aspects of chemistry like quantum theory, heat and electricity. Organic chemistry deals with the study of carbon and its compounds. Inorganic chemistry deals with the study of elements, their properties and uses. The scientific method of discovery The scientific method of discovery includes the following steps and stages: Observation Pattern Problem Hypothesis Experiments Theory Law Hypothesis refers to the prediction or guesses which explain an observed problem. When the hypothesis has been tested and found to be true within the limits of the available evidence, it becomes a theory. A theory which has been extensively tested and proven correct without any exception becomes a scientific law. Self-Evaluation Define Chemistry? State the stages or steps involved in scientific discoveries.? When does a theory become a scientific law? Applications of chemistry Chemistry is applied in our everyday life as different activities take place in the environment. The effect of chemistry is felt in different aspects of life such as cooking, washing with soaps or detergents, digestion of food, drugs, etc. Other applications of chemistry include health care, transportation, food, houses, and clothes. Careers prospects in chemistry There is a vast range of careers open to those who studied chemistry at any level. Great career opportunities exist both inside and outside the laboratory. You can choose a career from different fields such as: Chemical Engineering Biochemistry Industrial Chemistry Environmental Chemistry Pharmaceutical /drug development Mining and Metallurgy Science education Petroleum Engineering Quality control Medicine and surgery Pure and applied chemistry Science laboratory technology Self-Evaluation State five applications of chemistry in our daily life? Mention five adverse effects of chemicals and how they can be controlled. Mention ten career opportunities in chemistry? List the branches of chemistry?
