QUALITY OF WATER IN SCHOOL POND COMPARED TO SCHOOL CREEK

To determine the quality of water in the pond and creek To measure the acidity level of the water in the pond and creek

To measure the level of dissolved oxygen in the pond and creek

Objectives:

The researchers would like to determine the quality of water at the School Creek and the school pond at Panason Village by determining the acidity level and dissolved oxygen level in both study sites.

Rationale

The quality of water in an area determines the quality of life. If the water is clean, people will be healthy but if it is dirty there will be illness.

Background of study

The quality of any body of surface of ground water is a function of either both natural influences and human influences. Without human influences water quality would be determined by the weathering of bedrock minerals, by the atmospheric processes of evapotranspiration and the deposition of dust and salt by wind, by the natural leaching of organic matter and nutrients from soil, by hydrological factors that lead to runoff, and by biological processes within the aquatic environment that can alter the physical and chemical composition of water.

Related literature

Typically, water quality is determined by comparing the physical and chemical characteristics of a water sample with water quality guidelines or standards. Drinking water quality guidelines and standards are designed to enable the provision of clean and safe water for human consumption, thereby protecting human health. These are usually based on scientifically assessed acceptable levels of toxicity to either humans or aquatic organisms.

Statement of the problem

Is the school pond clean and safe for fishes as well as for children playing around it during their free time?

No one passes the creek because it is very smelly.

Everyone plays around the pond because it looks clean.

Additional background of study sites

The water in the creek is dirty. Animals cannot live in the creek.

Acidity Test

The level of dissolved oxygen in the school pond is high.

Dissolved Oxygen Test

Based on the study, the school pond has a lower acidity level compared to the school creek.

The dissolved oxygen level is higher in the school pond than the school creek.

Therefore, more marine life can survive in the school pond compared to the school creek.

Results and analysis

Clean the creek and remove the trash, so it will not smell bad and become polluted.

Keep the school pond clean all the time.

Action

For the school creek , residents nearby should not throw the trash in the water.

For the school pond, everyone should keep it clean by not throwing any trash in the water.

Recommendation

Students in Action

Students conduct the tests with the guidance of the teachers to ensure the validity of the tests.

Students understand the lessons better when lessons are conducted with hands-on

and research-centered activities.
