Jigsaw Task-Yeast Balloon

Jigsaw Task. 

This experiment is all jumbled. Your job is to put the experiment in order,  in a format that is clear
and logical. Just like what we do in class. You are to copy and paste this experiment in the
correct order. The  method is even jumbled

Title: Yeast Balloon

Aim

To explore the reaction when yeast is mixed with sugar and warm water to blow up a balloon.

Hypothesis

I think the balloon will blow up because yeast is used to make things rise. 

Equipment

300ml warm water

A packet of dry yeast

A spoon

A pitcher

Sugar

A small soda bottle

A balloon

Method

Pour 300mls of water into a bowl. 

Add a packet of dry yeast and add two tablespoons of sugar, and stir the mixture until the
yeast and the sugar has dissolved. 

Pour the mixture into the drinks bottle.

Warm up the balloon with your hands. To soften the rubber more, grip the ends of the
balloon and stretch it. 

Stretch the open end of the balloon over the neck of the bottle. Make sure it is pulled down over
the screw threads on the top of the bottle to prevent air from leaking.

Leave the bottle upright with the balloon fitted for one hour, then check the result!

Leave the balloon undisturbed overnight. In the morning the balloon will be even bigger! 

Results

I discovered that within ten minutes the balloon blew up. It blew up to the size of a cricket ball. 

Conclusion

The yeast needs sugar and water to activate it and it begins to respire (breathe). As it does this,
it creates the gas carbon dioxide, which is what blows up the balloon. Yeast is what we use to
make bread rise, so it is a very important little creature!
