My team and I did an experiment with different liquids and yeast.
Our question to our lab was How does different liquids affect the gasses yeast makes. I thought carbonated liquids would make more gasses but I learned just plain water and yeast made the most gas.
For our evidence we used balloons to catch the gas.
Our inaccuracies were not having enough balloons for each of our test tubes. We had three balloons and 6 test tubes. And on top of that one balloon got a hole. I observed the water and the yeast made the biggest balloon. I understand that my prediction was incorrect. I thought carbonated liquids mixed with yeast would blow up the biggest balloon but it was just water and yeast.
