| Explore | We had 4 dishes which we would put four drops of the pH solution so that the pH would remain the same, we put them in each week. We used the microscope to measure the percentage of growth along with discs of graph paper. The ferns remained under constant light when we weren’t looking at them. |
|---|---|
| Research Question | Our research question was how will changing the pH levels affect the C-fern's growth. We came up with this research question because we wanted to know what will happen to the plants if the pH levels will be basic or acidic. |
| Predictions | Our predictions about our C-ferns were that if the pH level is more neutral, the C-fern will grow faster. |
| Experimental Design | Our real plan is we wanted to test that the pH level of all of our plants closest to the ideal pH level which was 6.5 to grow faster. The dependent which we will measure, Dependent Variable, is the growth of the gametophytes. While the dependent which we will test, the Independent Variable, is the pH levels of our plants. |
| Conclusion | Our hypothesis was mostly correct and the c-ferns that were closer to 6 pH grew faster/more. 4 happened to be an outlier as it grew more than 7 even though it was farther away. Claim: The pH of six water will offer the most growth the fastest. Evidence: The final pH of both 6 and 4 were approximately 2.5 spores per square on the graph paper. |
