Yeast Air Balloon

Introduction yeast lives by feeding on kales, emission hundred dioxide. The more yeast that is added the more carbon dioxide testament be produced. barm combined with a dough creates so lots vaunt because in one gram of yeast in that location are ab appear 28 gazillion cells. Bubbles can be seen when the yeast is working. The process could be called fermentation. This working in a similar fashion to the beer making process. barm is a pillowcase of fungi when it has the right conditions (warmth and moisture) it grows. Yeast uses its make enzymes to break shoot food. However none of this is possible if profit is not register in the shuffle. dulcorate is the food that yeast relies upon to activate. The more sugar added the greater the gas and the greater the rise. orient: The aim of the prove is to see how much carbon dioxide is produced when contrastive amounts of yeast, water and sugar are mixed together in a flaskful with a fly coverin g the interruption to capture the gas produced. Hypothesis: If more yeast is added to the multifariousness then there will be more carbon dioxide created to make the blow up bigger.

Variables: Independent Variable: Yeast qualified Variable: Carbon Dioxide Controlled Variables: urine and Sugar Materials: -Yeast -Sugar -125ml Erlenmeyer Flask -4” inflate (Deflated) -Luke warm water -Masking Tape Method: 1. valuate out 5g yeast, 20g of sugar, ad 120ml of luke warm water (Less than 100 degrees F) 2. push finished yeast, sugar and water in a 125ml Erlenmeyer Flask. 3.Quickly profane the balloon over the open ing of the Erlenmeyer Flask. 4.Seal where t! he balloon and flask meet with tape. 5.Shake and get for the reaction to occur. 6.Measure the diam of the balloon at 2 slight intervals then succuss the flask again to further mix the contents.
