The aim of this experiment was to
blow up a balloon using yeast.
The yeast mixed with sugar and warm water will create
carbon dioxide.The carbon dioxide will blow up the
The equipment we used...
*1 300ml plastic bottle,
*1 small circle of paper,
*1 table spoon of yeast,
*1 teaspoon of sugar,
*1 tablespoon of water
The ﬁrst step was to draw around the bottom of a bottle
and create a funnel.
We then measured our ingredients, and our partner
helped us pour the ingredients into our funnel we had
Once the ingredients was in the bottle we placed the
balloon securely over the hole on the top.
We then put the bottle outside and began our written
work, every so often we would go and check on the bottle.
At the end of the day we had a ﬁnal
look at the balloons. I noticed that
everyone would end up with a different
conclusion, because most of the
balloons looked different. I think the
balloons could have been bigger if we
had tested with different measurements.
Even though some peoples experiment
didn’t work out I think we all had a lot
of fun. My balloon started to blow up
but it didn’t get really big.
