1. Everything is made of chemicals. You are made of chemicals. So is your dog. So is your desk. So is the sun. Drugs are chemicals. Food is made from chemicals. 2. Many of the changes you observe in the world around you are caused by chemical reactions. Examples include changing colors of leaves, cooking food and getting clean. 3. Knowing some chemistry can help you make day to day decisions that affect your life. Can I mix these household chemicals? What are safe mosquito repellents? Will my bottled water expire? Well, this involvement usually begins first thing each morning. Most people wake up to an alarm or radio. These common household items contain batteries, which make them very chemically dependent. These batteries contain positive and negative electrodes. The positive electrode consists of a carbon rod surrounded by a mixture of carbon and manganese dioxide. The negative electrode is made of zinc. Chemistry plays an important role in the discovery and understanding of materials contained in these and many other common household items. Things like household cleaners and water purification systems are vitally dependent on chemistry. Without chemistry something as simple as scrubbing a toilet without fear of severe burns or small explosions might not be possible.  Next, though it isn’t widely known, chemistry is also heavily involved with the manufacturing of things such as makeup and soap. Each time you bathe you are witnessing chemistry at work. Chemicals such as acetyl alcohol and propylene glycol are typical ingredients in the soap used to wash your hair and skin. Without chemistry, these materials (or combinations of these materials) might be hazardous or might not exist. The chemical coloring agents used in makeup and nail polish would not be possible without an understanding of the chemicals involved.  Almost anything you do during the course of a normal day involves chemistry in some way. The gas and tires in cars we drive, the makeup we put...
