General Information Dealing with RQ, Variables, and Hypothesis

Research Question: How does varying levels of pH of soil affect the life and sustainability of Umbrella Trees (Scheffiera arboricola)?

Independent Variable: pH level of soil 

-Alkaline soil

-Neutral soil

-Acidic soil

Dependent Variable: The life of the Umbrella Tree and its sustainability (ITS HEIGHT)

Hypothesis: If the pH of the soil is higher, then the Umbrella Tree will wither away and eventually die, because acidic soil prevents certain nutrients from being absorbed by the plants. Whereas, the Umbrella Tree will do much better in alkaline and neutral pH levels of their soil because they will be able to absorb all the necessary nutrients. Sustainability and plant life will, however, be at its most optimum level in a soil with neutral pH because that's when the conditions are seemingly just right for the Umbrella Trees to absorb all the nutrients required for survival.
