Chemistry is the study of the building blocks of all matter and the interactions between them. Physics focuses on physical changes, forces and energy. Chemistry takes that knowledge to see how matter is made up and changes in that matter. Biology completes the field of science by looking at living things and the effects chemical and physical changes have on them.
Telescopic Thinking
To understand chemistry you must develop “telescopic thinking”. First look at a change that is happening in front of you: an egg being fried, clothes being cleaned or a fire burning. Then, in your imagination, you must zoom in, down to the molecular level to see what is happening to cause the changes you see in reality. How is this done?
Elements, Compounds, Reactions
Chemists use various tools to do this important science. First is the understanding that all matter is made up of combinations of elements of which there are just over a hundred. Then there is the knowledge of the way these elements bond to one another to make compounds. Finally is the study of how these molecules react with other molecules in chemical reactions.
