| Explore | From outside of school we learned that plants need water and sunlight to survive and grow. We also knew that the take in carbon dioxide and produce oxygen. In school, we learned more about how plants create sugars through photosynthesis, and that the sugars can also be used as building blocks for the plants. We know that the consumers take the energy from the plants by eating them, and produce the things needed for plants to photosynthesize. |

| Research Question | We want to study how the level of acidity effects the growth and germination of plants. We came up with this question because we started thinking about pollution and acid rain and we wanted to figure out if acid rain effects the growth of plants. |
| Predictions | Our prediction is that the plants will likely grow better when there is less acidity in the water they are watered with. We suspect that the acid with harm the seeds and prevent, or at least hinder the growth and germination of the seeds |
| Experimental Design | We are going to plant our seeds in three different growth chambers. each chamber will contain 10 seeds. We will water our seeds with the same amount of water every day. The first chamber will get water with no acidity. The next chamber will get water with one drop of sulfuric acid, and the third chamber will have water with two drops of sulfuric acid. We will measure the color and strength of the plant, and also how large the stem and leaves of the plant grow. The temperature, amount of water, amount of light, and type of seed will stay the same. The only thing we will change is the acidity of the water. We will record our data in a chart to measure the qualitive data of the seeds, and a graph to measure the size and quantative data of the plant. |
