Often hard-to-understand concepts of air, gases, air pressure, and layers of the atmosphere are plainly explained in this video. Concepts and terminology: oxygen, nitrogen, layers, weather, jet stream, and northern lights.

NASCAR tires are filled with nitrogen to help protect against heat caused by friction. Friction also increases the air pressure in tires, and NASCAR drivers don't want a tire to blowout during a race. The use of nitrogen helps the crew predict how hot the tires will get. Part of "The Science of Speed" series.
Live-action weather footage helps students learn how they can observe the weather. Concepts and terminology discussed include: temperature, air pressure, weather systems, precipitation, and wind.
Weather is the state of the atmosphere, and it refers to the day-to-day temperature and precipitation activity. The difference between air pressure, temperature, and moisture influence weather-related phenomena. Other topics covered include evaporation, relative humidity, clouds, precipitation, rain gauge, air mass, front, thunderstorm, hurricane, tornado, weather forecast, meteorologist, and satellite imagery.
Suggests tips and ideas for conserving energy and water around the home. Touches on energy savers in the kitchen, for the water heater, and around windows. Covers recycling garbage and managing hazardous waste disposal.
Students explore the characteristics of fluids. Some topics they study include pressure and its impact on the behavior of fluids, Bernoulli’s and Pascal’s principles, and density and its effect on buoyancy. Additional concepts and terminology discussed include: hydraulic devices, particles, differences in pressure, air pressure, and buoyant force.
Bill Nye demonstrates simple experiments that can be done at home. These show scientific ideas about air pressure, weighing gas, bending light, static electricity, and others. Emphasizes that a good experiment is repeatable.
Weather affects everyone's life. This program provides illuminating, live-action examples and explanations of different weather patterns around the world. Students will also learn the layers of the atmosphere and be able to explain the causes and effects of air currents and air pressure. Part of the "Way Cool Science" series.
A hurricane hunter is a pilot that flies an airplane into the middle of a hurricane. They gather data on temperature, humidity, and air pressure. This data is critical for forecasting the intensity and path of hurricanes. Part of the "NOAA Ocean Today" series.
This video explores the daily condition of the Earth's atmosphere, and the factors that influence and cause weather. Special emphasis is given to the global processes that generate weather patterns. Other topics covered include conduction, convection, radiation, thermometer, barometer, air pressure, winds, anemometer, sea breeze, land breeze, doldrums, trade winds, prevailing westerlies, polar easterlies, and jet streams.
In a gas turbine, the linear motion of gas causes rotors to spin, ultimately creating electricity. The forward rotating blades pump air under high pressure into the combustion chamber where natural gas ignites on contact with the air. At 1,500 degrees Celsius, the stream of gas rushes past the rear turbine blades, causing the entire rotor to spin. A generator transforms that rotational energy into electricity.
Interviews with professionals and patients provide information on polluted air inside and outside, how it is caused, and what can be done about it. They also relate effects of breathing in polluted air, including asthma, emphysema, and chronic obstructive pulmonary disease and their treatments.
Humans have always been intrigued by the idea of flight. Experiments with Hot Air Balloons led to a pig and duck being the first air travel passengers. From there, the Wright Brothers created the first airplane, and aviation was off to the races. From the jet engine and military aircraft to passenger planes, worldwide travel is now a matter of hours rather than days or weeks.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term air. Part of the Science Video Vocab Series.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. The only contribution the kids in Ms. Frizzle's class have made to the Walkerville Space Capsule is an empty jar. But they soon discover the jar isn’t empty; it full of air. They learn the power of air when the bus shrinks and gets stuck inside the jar, and the class finds that their only hope for escape is... air.
Can "dirty" birds help scientists assess air pollution? Yes, and scientists have been using a species of birds to answer questions about levels of air pollution in the United States for over 135 years. Part of "The Brain Scoop" series.
Eco, the little bear, travels around the world observing human interactions with the environment. During his journey, he meets many other friends from the animal kingdom and gets a firsthand look into some of the environmental and social problems facing the planet. Eco and his friends provide ways for humans to ensure a healthy planet for the future. Part of "Eco S.O.S." series.
Follows the journey of a red blood cell around the circulatory system to demonstrate the efficient and elegant design of oxygen and food delivery to all parts of the body and the removal of wastes before they can do harm. Shows how the veins and arteries are structured to perform their tasks: muscular arteries to transmit the force of the heartbeat, veins with valves to insure the blood's return to the heart.
In this episode, host Joe Hanson discusses the science behind hot air balloons. He also explains the ideal gas law. Part of the "It's Okay to Be Smart" series.
