| Explore | I learned that microbes are pathogens because they both produce diseases. This impacts plant diseases because if the plants are strong enough, then they will survive, and if they are weak then they would be killed off by the diseases. I also learned that plants get their energy from a process called photosynthesis. They collect carbon dioxide and mix it with water then they receive sunlight to cause a chemical reaction that then creates glucose which the plant uses for energy and releases oxygen. |

| Research Question | Which of the three vegetables: Cucumber, Potato , and sweet potato will succumb to soft rot first |
| Predictions | Our hypothesis is that the Potato will be the first out of the three to succumb to soft rot. |
| Experimental Design | Gather materials : Cucumber, Potato, Sweet Potato, Damp paper towels, Sealable plastic bags, Toothpicks, Small beakers of bacterial inoculum, A 10% bleach solution containing two drops of dish soap, A large container for disinfecting the potatoes in 10% bleach, ,Microscopy equipment, Latex or nitrile gloves Our first step is to take the toothpick and dip it in bacterial solution and poke it into the vegetables; repeat for consistency Second step is to wrap the vegetables in a damp paper towel and seal the bag. Third step is to set the vegetables in the sun Fourth step is to make sure that the vegetables are soft, and if they are then your experiment has been successful Make sure to actively collect your results |
| Conclusion | Based off this experiment we can claim that Sweet Potatoes are less common to Soft Rot than the other two vegetables. This data protects our claim because in the bar graphs you can see that the Sweet Potatoes are the lowest which means that they have the least Soft rot length. Some future experiments that we can expand based on our results are seeing how many weeks it takes for the whole Sweet Potatoe to Soft Rot. |
