| Explore | Radishes are monocots that grow and develop in 4 weeks. Antibiotics supposedly inhibit plant and seed growth. The possibility of antibiotics being present in the water being used to water plants is a concern, and so is what will happen to wild plants and agriculture over time. If this project shows that antibiotics do not inhibit the growth of radishes, then antibiotics could be used to treat diseased radishes. |

| Research Question | What is the effect of different concentrations of antibiotics on the seed growth of Raphanus sativus? |
| Predictions | If higher concentrations of antibiotics are used during the Raphanus sativus seed development stages, then it will cause the seed to grow less. |
| Experimental Design | Independent Variable: Concentration of Antibiotics Dependent Variable: How tall the Raphanus sativus seeds will grow Procedures: 1. Put soil in 30 containers. 2. Put one seed in each container. 3. Cover each seed with soil. 4. Water each seed lightly 4-5 days a week with distilled water for 30 days. 5. Repeat step 1-4 with the other concentrations of antibiotics in the soil. 6. Observe seed germination daily, and once it germinates, measure the plant growth for all groups daily for 30 days. 7. Collect data from all groups and perform an one-way ANOVA test. |
