Beakman explains how diamonds are made from carbon and then describes what elements and compounds are. He combines sulfuric acid and sugar to create a black carbon substance that looks like coal to demo that carbon is in sugar. Then he uses an animated clip to explain how scientists think coal makes diamonds.

Walter teaches his chemistry class about the element, carbon, and its critical role in life. He explains that all life is carbon-based and gives examples of the prevalence of carbon in our lives.

Sophie explains how potholes occur in the street: when water seeps below the ground and freezes. She conducts an experiment to show how water expands when it freezes.

Jimmy and Lucy Liu perform science experiments with Kevin Delaney, including making a giant cloud using the power of chemical reactions. Kevin explains each experiment and the science behind it. As they introduce elements such as Hydrogen, Sulfur hexafluoride, and Nitrogen to the experiments, Kevin identifies the properties that make them unique.

A group of participants attempts to understand the purpose of the machine and the magnets given to them. After they put the magnets in the machine and turn it on, they notice that the magnets start to form complex structures on their own. The magnets symbolize atoms, and the experience suggests that compounds can form on their own over time, given a constant input of energy.
