Hands on Weather - Air

The video explores the properties of air through six demonstrations. It shows how air is invisible yet powerful, enabling kites to fly and creating wind. The demonstrations include using a fan to create wind, a blow dryer to show air's power, and balloons to illustrate air's space and movement. Air's strength is demonstrated by its ability to hold weight and change shape. The video also covers air pressure, showing how it prevents water from entering a bottle and creates waves in water. The importance of air in holding moisture and affecting temperature is highlighted.

Explain how air pressure works using the example of a cup of water.

What is the difference between warm air and cool air in terms of space and movement?
