| Explore | We know that seeds need sunlight, rich soil, and water to grow. That soaking 30 seeds in 3 different liquid |

| Research Question | How does putting a pea seed in different liquids affect the germination? |
| Predictions | The seed that is soaked in water will germinate the fastest, the seed that is soaked in soapy water will germinate the second fastest. Lastly I think that the seed soaked in coca cola will germinate last. I think this because you usually water seed with water, but there is a possibility that the seed can drown. I think soapy water will germinate the second fastest because soapy water is probably better for the seeds than the coca cola. I think that the seed soaked in coca cola will germinate last because I think that the carbonation, and bubbles will have a negative effect on the seed’s germination. |
| Experimental Design | 1. Get 30 pea seeds. 2.Fill 3 cups up to the 100 milliliter mark. Fill 1 beaker with caffeine free coca cola, fill the next cup with with soapy water, and fill the last cup with regular water. 3.Place 10 seeds in each cups. Drop them in at the same time. 4.Let these seeds sit for 24 hours. 5.Take the seeds out of the liquid. 6.Record what these seeds look like. 7.Place the seeds in the petri dish, careful not to mix the different liquid soaked seeds. 8.Observe, and wait to see how the seeds germinate. |
| Conclusion | Natural plants and objects can't be exposed to synthetic or improper materials if intended to grow. The Coca Cola and soapy water weren't reliable because they weren't natural. The seed had never been exposed to Coca Cola or soap in it's natural environment so it was not prepared to "meet with it".The regular water worked the best over all, but there was a "dud" seed. It wouldn't grow, it wouldn't do anything. The soapy water had 10 fully germinated seeds, but they weren't as developed than the regular water's 9 seeds that had roots and stems and leaves. Overall, this experiment could have gone either way, and you can argue about which one, soapy water or regular tap water, worked better. |
