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.

What is one way air demonstrates its ability to move objects?

• By making a pinwheel spin

• By changing the color of leaves

• By making water freeze

• By creating sound waves

What happens to a balloon when air is released from it?

• It gets smaller

• It changes color

• It becomes larger

• It stays the same size

How does air inside a balloon demonstrate its ability to hold weight?

• By keeping the balloon from popping when sat on

• By making the balloon float

• By changing the balloon's color

• By making the balloon disappear

What prevents water from entering an upside-down bottle submerged in water?

• The air inside the bottle

• The color of the bottle

• The temperature of the water

• The weight of the bottle

Why do hot air balloons float?

• Because cool air rises

• Because warm air expands and rises

• Because they are filled with helium

• Because they are lighter than air
