3 Chapter 1 Introduction Chemistry is a science that deals with the study of matter and its changes. Chemistry is a branch of natural sciences. It is interrelated with all other sciences. Simply chemistry is in everything. It has a lot of branches; biochemistry, organic chemistry, analytical chemistry, physical chemistry, electrochemistry, nuclear chemistry, thermo chemistry…etc.

4 Chapter 1 1. Why Chemistry? Chemistry is everywhere.

5 Chapter 1 2. What is a Science? Science means knowledge in Latin. The studies conducted and tested systematically, hypothesized and shared with people are called scientific studies. A chemist who studies chemistry. The applications of scientific principles in the service of mankind is called technology. All scientific studies have certain steps; observation, hypothesis, experiment and sharing results.

8 Chapter 1 3. Experimental World of Chemistry Steps of an experiment in chemistry as follow; Setting up the experimental equipment and procedures, Conducting the experiment, Recording data, Analyzing results, reaching a conclusion and sharing results. Safety always comes first. Always listen carefully to all instructions given by your teacher. Learn necessary safety rules for your experiment.

9 Chapter 1 3. Experimental World of Chemistry Safety always comes first. Always wear a lab jacket and safety goggles. Read all the necessary information about the experiments. Wear gloves when using heat, chemicals and glassware. Do not throw any chemicals. Do not touch any chemicals with your fingers. Tie long hair. Do not horse around in a lab. Quickly report all accidents to your teacher. Do not eat, smell, drink or taste any chemical.
