During our 'See, think, wonder' task at the start of our programme of inquiry we came up with some interesting questions about balloons. So we did some exploration and some more wondering...
Pushing our breath into the balloons was hard and we were excited by the push of the air coming out and the funny way the balloons travelled across the room as the air escaped. The noise was interesting too - by varying the size of the mouth of the balloon we could change the sound. Sometimes it was very high-pitched.
We worked out that this push, powering the balloon forward, would allow us to make a balloon rocket.
We also found out that gas is produced/released when some ingredients are combined. This gas can be contained and will inflate a balloon.
