Hank talks about how scientists may have found the missing link, a gene, that can give them more insight in to how plants went from living in the ocean to moving on to land.
Hank explains in-depth the series of reactions that take place for a plant to produce food for itself, also known as photosynthesis. This video also explores the prerequisites (sunlight, carbon dioxide, and water) of these reactions.

Bill Nye narrates the story of how photosynthesis was discovered. He explains the hypothesis of the experiment that shed light on how plants generate energy.
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.
Drug resistant bacteria or superbugs are bacteria that have become resistant to antibiotics. This clip discusses how superbugs form and scientists are trying to find ways to fight off these super bugs.
