Yeast Air Balloon

Introduction yeast lives by supply on kales, expelling i C dioxide. The to a greater extent yeast that is added the more(prenominal)(prenominal) carbon dioxide will be produced. barm combined with a dough creates so separate vaunt because in one gram of yeast in that location are some 28 billion cells. Bubbles loafer be seen when the yeast is working. The mathematical operation could be called fermentation. This works in a similar agency to the beer making process. barm is a pillowcase of fungi when it has the unspoilt conditions ( cordiallyth and moisture) it grows. barm uses its own enzymes to break of serve shoot food. However no(prenominal) of this is possible if sugar is not register in the mixed bag. dulcify is the food that yeast relies upon to activate. The more sugar added the greater the boast and the greater the rise. Aim: The point of the prove is to see how overmuch carbon dioxide is produced when different amounts of yeast, peeing and sugar are conflate together in a flaskful with a vaporise covering the opening to bring the gas produced. Hypothesis: If more yeast is added to the mixture whence there will be more carbon dioxide created to halt the w impart bigger.

variables: Independent Variable: Yeast Dependant Variable: coke Dioxide Controlled Variables: urine and Sugar Materials: -Yeast -Sugar -125ml Erlenmeyer Flask -4” billow (Deflated) -Luke warm peeing -Masking Tape Method: 1. valuate stunned 5g yeast, 20g of sugar, ad 120ml of luke warm water (Less than 100 degrees F) 2. push with yeast, sugar and water in a 125ml Erlenmeyer Flask. 3.Quickly profane the fly over the opening of the Erlenmeyer Flask. 4.Seal where the balloon and flask meet with tape. 5.Shake and allow for the reaction to occur. 6.Measure the diam of the balloon at 2 second intervals then succuss the flask again to further mix the contents.
