rose12345:

Write a scientific question about the hot-air balloons. How do hot air balloons land? b. Write a hypothesis for your question.

NotLeiland:

I think that hot air balloons land due to the reduction of heat in the balloon produced by the fire. When the fire is slowed, the balloon lowers.

TheKaylaHope:

hypothesis: Hot air balloons land by decreasing the temperature of the air inside the envelope using the venting mechanism or by adding ballast to the basket which is heavier than the balloon, allowing the balloon to descend to the ground.
