Our Assembly

If you missed our assembly this term we had fun performing a Jump Jam routine, the whole school got involved and we shared our paper mache hot air balloons. Lofa read her writing about how they fly. Here it is;

WALT: explain how a hot air balloon flies.
Today I am going to tell you how a hot air balloon flies high
in the sky.The forces of flight are lift, weight, thrust and drag.


Lift is a force that makes an object go up. The fire from the
bunsen burner causes the air to be trapped in the hot air
balloon. It lifts upwards when the anchor is released
because hot air rises.


Weight is a force the makes an object go down weight
is also like gravity and how when we jump we are brought
back down to the ground. When you stop the fire the balloon
is pulled down slowly by gravity.


Also the hot air balloon is deflated so it doesn’t automatically
stick up, you have to fill it up on it’s side.

I wonder if hot air balloons can stop in one place for a long
time without moving?


Thank you for listening to my explanation.
