Chapter III
Methodology
In formulating this Project Based Learning which is entitled “Determining Water Current of Silway River at Prk.3 PI Barangay Dadangias North, General Santos City through Streamflow Analysis before and after rainfall”, the researchers gone through a serious discussion and researched. The researchers then decide a better topic and the area where it is possibly conducted. The researchers considered the area and the calamity that currently happened last month. Then the researchers choose the Silway River as the subject area to be conducted.
The researchers decided that the best time to conduct this activity is before and rainfall which the water stream flow is best to compare.
The researchers sent a letter to the barangay captain ofDadangias North General Santos City to allow researchers to conduct the said research. After the researchers received the letter, they started to prepare the equipments to use. The researcher prepare a borrower’s slip to borrowequipment, namely, the field thermometer to exactly measure the temperature of the target area, the 50 meter transect line to measure the diameter of the river, the 1X1mm Styrofoam that serves as the instrument in determining the stream flow of the Silway River.
After the researchers completed the materials needed, the researchers are now ready to conducts thefield experiment. March 2, 2012, finally, the researcher conducted thepreliminary experiment and on March 10, 2012 we completed the experiment.
When the researcher approached the site of chosen area the researcher then started their work. First the researcher chose an area best suited in the test. The researchers started their experiment by measuring the diameter of the river, its depth and temperature.
After all those measurements, the researcher now ready to measure the stream flow of the water or the current of the water using the Styrofoam and timer. The researchers measure the time that the Styrofoam travels from the starting point to the end point. The researcher replicates five trials to make sure that the results are accurate and precise.
After the data gatherings completed, the researchers started to analyzed the result of their study.
