RMcCabe - Up and Up

This week in our ‘How Will We Get There?’ topic we have been thinking about adventures in hot air balloons.

·    What might your balloon look like?

·    Where might it take you?

·    How does it work?

These have been some of our key questions fuelling our discussion, writing and independent time.

We have been experimenting with hot and cold air to see how a hot air balloon works. When we put an empty bottle in cold water the air stayed in the bottle. However when we put the bottle in hot water, the air inside warmed up and rose to the top and began to inflate the balloon. If we squeezed the balloon gently, we could feel the air inside!
