Project Title 2: Investigation on the pH level of rainwaters collated around SST.
Hypothesis: The more polluted the air is in a location that the rainwater is located in SST, the lower the pH level.

Rainwater is water in form of droplets that are condensed from atmospheric water vapour and precipitated until it is heavy enough to fall because of gravity. Rain is important to the water cycle as it deposits the most fresh water on Earth. Also, rain provides a lot of suitable condition for the eco-system. Rainwater varies in terms of the pH level, mostly due to its origin. The places of where rainwater is from affects the pH level of it. For an example, rain that is collected from the Atlantic Ocean has a pH level of 5.0 to 5.6. (Whereas, rain that is collected across the continental from the west has a pH level of 3.8 to 4.8. With that, we want to know on how the location of where the rainwater is collected affects the pH level and what are the factors that would change the pH level of the rainwater collected in SST.
