My results were fairly reliable, and are very accurate. Beans grow best with fences, poles etc. to climb up. They also prefer full sun. Most of the beans did sprout, but the ones that did probably did not get full sun due to their position. Another factor to explain my results, is the water amount. This was my independent variable, so this was purposely changed. Beans do not like to be over watered, so this explains the 20 mL group not sprouting. My results can be explained by the amount of water they were given and the viability of the seeds. Not all seeds germinate no matter what you do, my average viability rate was about 50 - 60 percent. I think that the reason for 50 % of my seeds sprouting is due to the water that they were given. …show more content…
What errors or limitations in your experiment may have affected your results? An error or limitation that may have affected my results are variables that were beyond my control. I could not control how much dew the bags absorbed so they may have had slightly different water amounts. Another limitation that may have affected the results, that was beyond my control was temperature. Although all the seeds the seeds would have had the same temperature, the temperature was not consistent throughout the experiment. Plants thrive in hot and humid conditions, if the temperature is cold, the plants may not be able to germinate as well as in warmer conditions. An error that I made was probably my measurement increments. Although this did not affect the experiment it did have an effect on the results. The measurement increments did have extremities (5 mL and 20 mL), but the 20 mL seeds literally drowned. Only one of these seeds sprouted with the rest of them being over watered. If the experiment was to take place again, the measurement increments would probably have been 2.5 mL, 5 mL, 7.5 mL and 10mL. Suggest any improvements to the experiment to reduce any
