2. Were you surprised by the results of your experiment? Yes, I was surprised because I thought water would accelerate the growth of bread mold. 3. What part of designing and carrying out an experiment did you find difficult? This was not that hard of an experiment, I did not find one part to be more difficult than the any of the other parts.

4. If you were to do further research into bread mold growth, which of the other variables old you be interested in testing.

I would be interested in air as a variable because think it affected my research on water and bread mold. Conclusion: The data does not support my hypothesis on water making bread mold grow faster. I don’t think this was a good experiment because we put the bread in an airtight cup by covering the top with plastic wrap and putting a rubber band around it. If this was useable data it would show the 11 drops of water was not near enough water to make bread mold grow any faster.
