| Research Question | How does the level of Ph affect seed germination? |
|---|---|
| Predictions | If we changed the pH level of the water to a higher intensity, then the seed will take a longer time to germinate therefore causing deformations in the plant. This is because the chemical toxins will slow the germination process down, and cause the seed coat and many layers of the seed to uncover, having deformations in the plant. |
| Experimental Design | Our Procedure Lab Procedure Place three buckwheat seeds in 3 Petri dishes Observe, take photos, and measure the unplanted seeds Cut out two paper circles for each petri dish Place the three seeds evenly spaced out in each dish Fill three spray bottles almost all the way full with water Set aside one of the spray bottles and label it “Normal pH water” Take another bottle and add 4 teaspoons of baking soda into it Stir well Label the same bottle “Medium pH water” Take the last bottle and add 8 teaspoons of baking soda into it Stir well Label the last bottle “High pH water” Assign each bottle to a petri dish and spray the seeds 5 times Continue to spray the water in the designated dish, once every day Take a photo each day of the seeds in approximately the same place Sketch the seeds at the same time that you take the photo Continue this for _ number of days At the end of the _ days, observe the difference between the three Petri dishes |
