Live-action weather footage helps students learn how they can observe the weather. Concepts and terminology: temperature, air pressure, weather systems, precipitation, and wind.

This video guides you through the basic operation of a chiller, making use of animations, illustrations, 3D models and real world photographs to help build your HVAC understanding.

This covers the basics of a air cooled chiller in...

NASCAR tires don't have "air pressure" because they're filled with nitrogen. The culprit responsible for increasing tire pressure during a race is friction. Using dry nitrogen gas helps the team predict how hot the tire will get and how...

Bridges. Bridges don't deal well with temperature changes. In order to combat this, engineers have come up with some work arounds that allow bridges to flex as they expand or contract. In this episode of Crash Course Physics, Shini talks...

Variable air volume hvac system basics. In this video we look at the basics of VAV ventilation system covering vav variable air volume systems used in hvac ventilation design, vav terminals, ahu air handling units, fan assisted vav...

In this video we look iat variable air volume systems (VAV) to learn how it works and how the system operates . We use 3D models, animations and real life photos to help you understand and learn HVAC engineering.<br/>

This video is about compressed air cans (aka gas dusters) and why they get cold when you spray them. They cool off because the refrigerant inside (1,1-difluoroethane) is under pressure and boils off when the...

What makes a tornado nature's most dangerous storm? Scientists are working to identify the unique set of circumstances which combine to create a tornado. Earth Science - Weather - Learning Points. Tornadoes are a violent, spinning vortex...

This video discusses the Haber process used to manufacture ammonia, which can be used to produce nitrogen-based fertilizers as well as nitric acid. It explains the reaction between hydrogen from natural gas and nitrogen from the air to...

How do the clouds closest to the Earth affect our weather? How are they formed and what do they look like? Earth Science - Weather - Learning Points. Temperature, humidity and air pressure produce ten different types of cloud. Those at...

Friendly and fun host Max Orbit asks questions about the world and searches for answers. This DVD series is designed to engage students while introducing scientific principles and concepts in a fun and entertaining way. Viewers will come...

Everyday we experience weather. This interesting series of programs helps students understand the factors that contribute to weather formation. Real-life examples enable students to appreciate the different aspects of weather....

This video explores the daily condition of the Earth's atmosphere. The factors that influence the atmosphere and cause weather are discussed. Special emphasis is given to the global processes that generate weather patterns. Other...

An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln...

This is an impressive but simple experiment for children. We did it with Alex about two years ago, so it was Max's turn now. But this time I added a bit of a twist though. I spread food colouring on the bottom of tea candle, lighted it...

Wind is everywhere. The air is constantly moving, sometimes gently, sometimes violently. Why? Pressure, temperature and rotation come together to make wind. Here's how.

The cold air produced by ACs is not inherently harmful. However, you may start to see symptoms of air conditioning sickness if your AC fails to restrain the bacteria, mold, fungi, dander, etc., that are thriving in the air-conditioned...
