What events cause the balloon to take off?

• A strong fan is used to blow up the balloon. A burner heats the air inside the balloon.

• A strong wind picks the balloon up off the ground.

• A strong fire picks the balloon up off the ground.

How does fire help the balloon fly?

• Fire puts off gas that is cool enough to make it leave the ground.

• Fire heats the air. Since hot air is lighter than cold air, the balloon rises.

• Fire doesn't help the balloon fly.

• The balloon catches on fire and lifts it off the ground.

What historical events had an effect on ballooning?

• kite flying and fire

• drawings, kite flying, and silk.

• lighting a fire under paper

• kite flying, stories, drawings, lighting a fire under paper and silk.

What is the effect of heating the air inside the balloon?

• Nothing the balloon stays on the ground.

• The balloon falls over.

• The balloon rises.

• The balloon barely lifts off the ground.

What causes the balloon to sink toward the ground?

• The pilot stops the fire and falls.

• The pilot does nothing and waits for the wind to change.

• The pilot holds his breath and hopes it goes well.

• The pilot pulls a cord.

How does letting out hot air make the balloon sink?

• Since there is more hot air, the balloon can keep the same weight in the air.

• Since there is less hot air, the balloon cannot keep the same weight in the air.

• Since there is less hot air, it doesn't matter what happens to the balloon.

• Since there is more hot air, the balloon will land fine.

What causes pilots to always check the weather?

• Pilots can control how the balloon moves, and can move the balloon how they want.

• Pilots don't care about the weather.

• Pilots want to keep everyone safe before the go on a flight.

• Pilots cannot control how the balloon moves, and need to make sure the wind is calm and the air is cool.

How does the wind affect a hot air balloon flight?

• The pilot must use the wind currents to control the direction the balloons travels.

• The pilot must not care about the wind and how it controls the balloons travels.

• The pilot checks the wind and then flies.

• The wind doesn't affect a hot air balloon.
