This program underscores how chemistry affects all aspects of life. Several expert guests discuss chemistry terms and concepts in various applications. A glass blower discusses the three states of matter - solid, liquid, and gas - and how heat can transform one to another. Matter is grouped into elements, mixtures, and compounds. Elements are composed of protons and neutrons in nucleus, as well as electrons. Compounds are two or more elements in specific proportions that have been chemically combined. Mixtures combine elements or compounds in any amounts. A cook demonstrates how heating sugar until it becomes caramel changes one compound into another. The program shows a scientist studying the chemical structure of plants in order to improve the strength of lumber. Two Test Connection segments feature the host reviewing previous concepts, including the difference between mixtures and compounds, and the arrangement of the periodic table of elements based on atomic number.
