| Explore | We know that plants need water, sun, and nutrients. Dirt absorbed more water than sand and sand and dirt combined. We want to know how flowers get their colors. |

| Research Question | How does planting radishes in different mediums affect the size of the plant outcome? |
| Predictions | f a radish was planted in the potting soil it will grow larger than a radish planted in the sand. |
| Experimental Design | We would plant the radishes in the potting soil, sand, and even ratios of soil and sand. Our control group is the amount of water each radish plant will receive. Our independent variable is the soil. Our dependent variable is plant growth. We are going to have three groups of soil each with 5 radishes planted in them. First, we are going to cover the surface with potting soil that is an inch deep, sand that is an inch deep, and an equal mix of sand and potting soil that is an inch deep. Then we are going to plant our radishes 6 inches apart and 1/2 inch down. Next, we are going to water them each 50 mL every Monday. We are going to measure them every Friday from the dirt to the top of the radish. |
| Conclusion | The radishes grew taller in the potting soil compared to the sand or the mixed soil. |
