Experiment on Yeast cell

Today, we are experimenting about yeast cell. As you know, yeast produce Carbon Dioxide and Alcohol when they grow and divide. We are proving too that cell need energy to grow. So, we have an experiment. First, pour 250 ml of hot water to a flask 1 and flask 2 (we need 2 flasks) . Add a teaspoon of Fermipan yeast and a teaspoon of  sugar to flask 1 and only a teaspoon of yeast to flask 2. Cover both flask with a baloon. Here how it works: mesure the ballon every 5 minute. As the yeast grow and divide, it produce more carbon dioxide and alcohol. The flask with most cell will have a bigger baloon. You will find out that Flask 1's baloon is bigger than the flask 2's baloon. This is because the sugar in flask 1 provide energy for the yeast to grow and multiply faster. The more yeast present, the more carbon dioxide and alchohol are produced.

This is my team at work, I'm the far right

 

This is the result, the big baloon is flask 1 and the small one is the flask 2

Thats all for today bye!
