Nye, Bill

Bill Nye explores the physiology and psychology of drug addiction, examining whether it is a disease, a chosen behavior, or a genetic disorder. Nye talks with scientists who are using diagnostic imaging to study the effect of drugs on the brain. Features an interview with psychologists who discuss the social factors associated with substance abuse and support their theory by conducting an experiment using non-alcoholic beer. Also speaks with a group of people who are struggling with drug addictions.

Examines the "stuff" that people use every day and looks at the effects that these everyday objects and actions have on Earth's environment.

Bill Nye explores the habits and behavior of spiders and examines the unique anatomy of these arthropods. The science guy explains how these eight-legged predators spin silk webs to capture their food. Discusses why spiders preying on insects is essential to balancing the ecosystem. Identifies several spiders from crab spiders to tarantulas and visits a forest habitat to reveal the wide variety of spiders living in the vegetation.

The science guy describes the physical features of the ocean and explores the ocean bottom. Explains how ocean pressure impacts objects, including a human being's ability to breath underwater. Measures the depth of the ocean and illustrates how the Earth's surface and the ocean floor are physically similar. Features how marine biologists and scientists use submarines and remote submersibles to examine the ocean bottom and identify the marine life that inhabit these deep waters.

Introduces the various paths by which people travel including on the ground, in the air, and on water. Identifies the vehicles used in each form of transportation, such as cars, airplanes, boats, and trains. Explores how humans invented different methods of transportation based on their needs and their environment and examines methods of mass transportation.

The science guy explores the physical characteristics of fish and explains how they adapt to their marine environment. Examines how the anatomy of fish is similar to human anatomy in a variety of ways. Illustrates how fish use their muscles to swim and their gills to breathe underwater. Presents experiments to demonstrate how air mixes with water and how fish get oxygen from water. Underwater cinematography provides an upclose view of a variety of marine fishes. Also features segments on the behavior of salmon and sharks.
