4. HYPOTHESIS We believed that the seed with the pH level of 6 (water) would have a greater success growth rate than the other seeds. The reason being was because of the simple fact that the higher the pH, the more basic, whereas the lower the pH, the more acidic. Anyone would believe the seeds placed in the water would germinate the quickest despite the level of pH anyway.

Place folded paper towel in each Petri dish Place folded paper towel in each Petri dish Determine the pH of each liquid and make note of it on the Petri dish (e.g. Water pH.6). Also, label each container with water, starch, vinegar… Determine the pH of each liquid and make note of it on the Petri dish (e.g. Water pH.6). Also, label each container with water, starch, vinegar… Place seeds (two in each Petri dish) in the container. Place seeds (two in each Petri dish) in the container. Once the seeds are in the container, let them soak overnight and cover them with 2-3 com of liquid. Once the seeds are in the container, let them soak overnight and cover them with 2-3 com of liquid. Place each Petri dish under artificial light. Place each Petri dish under artificial light. Everyday, make note of the changes you see. Everyday, make note of the changes you see. Each day, for the next 14 days, closely observe the seeds and keep them moist, dropping 2-3 cm of liquid each day.

6. RESULTS Two weeks ago, when the experiment began, we started off with the same procedure except the seeds weren’t placed under an artificial light. Instead they were placed in the window sill for a natural effect. We supposed that the natural sunlight would have a better effect on the seeds. However, we were wrong. Our experiment was not successful. After conducting the experiment for the second time, there was success. The seeds were placed under an artificial light and the growth rate was successful, but only in one particular seed, and that was the seed placed in the water. Unfortunately the germinations success growth rate for the other seeds was unsuccessful.

7. CONCLUSION After completing the experiment, we have finally come to a conclusion: the seeds under the pH level of 6’s (water) success growth rate were successful and germinated the quickest, whereas the other seeds haven’t germinated at all. They remained dormant throughout the whole experiment, even after doing the experiment twice. The first time around, the natural sunlight had no effect on any of the seeds. The second time around, when the seeds were placed under the artificial light, there was success. However, there was only success in one seed and that was the seed placed in the water which had a pH level of 6.
