| Explore | I know that plants use photosynthesis to get light and energy and make it into food for the plant. We have discovered that plants don't need anything to suck up the water from the soil it just absorbs it and gives water to the plant. We also learned that there are hairs on the roots of the plant that help absorb water. The questions about plants that interest us are how do they produce oxygen? JS, JSM, JN, JC |

| Research Question | Our question is how will a basil plant react with water, with out water, and one with some orange juice and water in it. We wanted to test whether or not water is the best liquid for plants. We want to get one plant with no water, one plant with water, and one plant with orange juice and see what the outcome for each will be. Whichever plant grows the tallest and has a good structure determines which liquid is better. JC, JS, JN, JSM |
| Predictions | We think that the plant we are going to pour water to is going to grow. For the one that has no water, it's going to die. For the late one that has water + acidic water (orange juice), it's going to grow but at a slow rate. JSM, JN, JC, JS |
| Experimental Design | Our plan is to see what plant grows the tallest and overall looks healthy. First we are going to have the plants grow by providing it water and light. After they all sprouts into the cups. Then, out of the three cups, we are going to keep giving one of the plants waters. We are going to stop giving the other plant water. Then for the last plant we are, instead of giving it just water, going to give it orange juice with water. We are going to measure how tall the plants are and we are looking at how well the plants look structure wise. We will record our data by measuring them everyday when we start the experiment. Then we are going to describe how they look. JSM |
| Conclusion | We can claim that while lemon water did decent, water is still the dominant liquid. This is because plants have used water since forever, which indicate that water has the perfect amount of nutrients for a plant. The data supports this because the water grew the best and that was the only thing that changed. all the plants had the same watering schedule, sunlight exposure, and amount of water/ liquid. A future experiment that would be good is if you keep the experiment going until the plants stop growing to see how much of a difference there is. JN |
