This video describes the advances in firefighting and the types of pumps they used over the years to put out larger scale fires.

Beakman puts raisins in some soda and notes that the raisins rise and fall. He explains that this phenomena occurs because carbon dioxide bubbles from the carbonated beverage carry the raisins up to the surface of the liquid and that they fall back down once they reach the air.

Beakman talks about how important oxygen is and why we need it to live. Beakman acts like Joseph Priestly to explain that oxygen is needed for us to create energy. He uses an engine and a candle as demos to explain the need for oxygen to burn fuel.

Phil tries to create carbonation on his own and initially fails. He consults his Book of Science to learn more about what makes drinks fizz. He learns that the container of the drink needs to be pressurized and later explains the behavior of carbon dioxide. He makes sure to clarify that carbonation is not a chemical reaction.

Beakman explains how leaves lose chlorophyll using a cartoon video. Then he explains the role of chlorophlyll in photosynthesis verbally. To further demonstrate, Beakman acts like the "chef" chlorophyll that provides food for the plant.
