| Explore | We had a minimal amount of knowledge about plants. We knew why plants were green because the plants reflect green light. We have discovered a lot about plants. We have learned about how they reproduce. C-ferns use spores instead of seeds to germinate and reproduce. A question that interests us in how a plant can become a hybrid plant. |

| Research Question | How does serial dilution effect the density of the spores? |
| Predictions | We think that the more diluted the serum becomes, the less dense the spores will become, resulting in a larger male to female ratio. |
| Experimental Design | 1. Have four dishes to inoculate. 2. Standard inoculation a dish. 3. Dilute the serum in 10 ml of water and inoculate a dish 4. Dilute the serum in 15 ml of water and inoculate a dish 5. Dilute the serum in 20 ml of water and inoculate a dish 6. Count the original amount of spores in the dishes 7. On the tenth and twelfth day count the amount of males and females 8. Record our data |
| Conclusion | We concluded that the more serial dilution that the serum undergoes, the higher the ratio of females to males will be. |
