Variables:
Manipulated Variables:
* Different Concentration of Hydrogen Peroxide (0.1%, 0.2%, 0.3%, 0.4%, 0.5%)
Responding Variable:
* The reply rate of the equation with catalase in the five different concentrations of heat content peroxide
Controlled Variables:
-Same amount of yeast (catalase)
-10mL of total heat peroxide in from each one test tube
-the written report disks were all the same
-all lab equipment was cleaned between each use to ensure no contamination of different percentages of hydrogen peroxide
data Collection and Processing:
Qualitative Data:
-The hydrogen peroxide was a clear liquid with no particles in it
-The yeast had chunks in the bottom, it was not stirred well
-The yeast was a yellow/brown colour when we dipped paper stacks into it
-When the response involving the Catalase occurred we could see tiny oxygen molecules begin to form on top of the yeast paper disk
-The bubbles of oxygen made the paper disc float back up to the surface
Quantitative Data:
Raw Data:
era it took for the yeast paper circle to rise to the surface of the 10m ±1mL of solution for:
