| Explore | We know that plants go through photosynthesis and cellular respiration. |

| Research Question | How plants react when given a solution with soap and water? We came up with this question to simulate the environment that plants outside of carwashes experience. |
| Predictions | The possible outcome is for the phenotypic ratio to change based on the chemicals that the plants received. |
| Experimental Design | OUr plan is to give each plant 10 mml of the soap and water solution every other day. We mixed 100 drops of soap into a cup of 400 ml of water and used syringes to extract 10 ml from the cup to water each plant. The variable we are testing is the growth and color of the plant at the end of the process. We will measure the growth and color. The amount of water use in use cell. We will observe how much each plants grows and the color of the leaves and stems change over time. |
| Conclusion | Last week we observed the ratio of purple to green stems as 1:1.13. Today as we check our plants again the ratio is 1:1.38 (purple : non purple). This is not the same as our expected 3:1 ratio. We think the results turned out this way because the chemicals in the soap may not have bee healthy for the plant or may have given them a lesser amount of something they needed to survive. This shows that the chemical imbalances could have caused a mutation in the making of proteins and the analyzing of the new DNA those proteins made. In our data it only resulted in the death of 5 plants out of 36. This shows that plant outside of a car wash, for example, CAN survive, but it may have a difference in its expected phenotypic ratio |
