Aim: To study pH value of rain water from different
locations.Variable: Manipulated Variable: Rain water from different
locations Responding Variable: pH value of rain waterIndependent
Variable: volume of rain water
APPARATUS and MATERIALS:
RAIN GAUGE and MEASURING CYLINDERSAMPLE OF RAIN WATER FROM
DIFFERENT LOCATIONS.pH METER
METHODS:1. Collect sample of rain water from different locations
by using a rain gauge.2. pH values from each sample is taken
byusing pH meter.3. Record the findings in the table below.4. Draw
the bar graph of the pH value against location of rain water
sampling.
Observation:
Conclusion:
From our project, we can make a conclusion that pH value of the
rain water is related to its location. The pH value in the
industrial area is lowest compared to other locations.
