Reflection
The combination of science and geography.So we went to the clang river to get the pH levels and check the pollution level of the river water.We had to find out the cause and consequences of the pollution.We learned to reduce and find ways to maintain the cleanliness.The river is used for passing time by doing water activities.We collected some of the river water and went to our science teacher to test for its pH level.The pH level was 9, which tells us that the water was alkaline. We took the temperature of both the surroundings and the water, which was 0.03 degrees celsius in difference.After this,we took the water specimen back to school to test for the presence of bacteria.
ANOTHER MEMORY LEFT BEHIND..
