In this lab we got a beaker and filled it with water and H2O2. Then we would add drops of yeast to the experiment. The reactions of the yeast with the mixture makes pressure. We then measured the pressure over a 3 minute time period and graphed it. To set up for the lab we had to connect a pressure sensor onto the beaker. Then run the data through a computer program to graph the data.
In this part of the experiment we tested with different amounts of drops. We found that we got the most reactions and pressure at 25 drops.
In this experiment we tested how the yeast reacted in different temperatures. It reacted the most at 38 degrees Celsius.
In this experiment we tested the pressure with different amounts of PH. We noticed that there was a lot less reactions happening at the PH of 7.
