Bread Mold Experiment Lab Report
Title Bread Mold LabPurpose The purpose of this science lab was to test the effect of water on incision mold growth. conjecture I hypothesized refined sugar mold would grow faster if the bread was undefended to water.Materials BreadPlastic cupWaterRubber bandPlastic wrapLightScaleSeizers ProceduresDay 1.Cut two pieces of bread 1 by 1Place the beard in two separate cupsPut 11 drops of water on superstar of the pieces of breadCover cups with pliant wrapPut rubber bands around each cupPlace cups on scale to weigh themDay 2. chance the mold or any transplants to the breadReweigh bread to see the difference in weightRecord your dataDispose of the bread and/or of the moldData Both pieces of bread were stale. There was no bread mold on ether pieces of bread. The bread stayed the same size. No change in the color of the bread. Weight of bread before and after a weekBefore one week 5. 5 gramsAfter one week 5. 5 gramsDry bread 5. 5 gramsMoist bread 6. 0 gramsQuestions 1. What does you r data press out about the effect of your Variable on Rhizopus growth?The data from my experiment show that 11 drops of water does non help the growth of bread mold.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 query into bread mold growth, which of the other variables would you be interested in testing.I would be interested in air as a variable because I regard it affected my research on water and bread mold. endpoint The data does not support my hypothesis on water devising bread mold grow faster. I dont think this was a good experiment because we put the bread in an gas-tight cup by covering the top with plastic wrap and place a rubber band around it. If t his was useable data it would show the 11 drops of water was not near enough water to operate bread mold grow any faster.
