Precautions

(Be sure to pay attention to safety)

1. Parents are required to accompany them;

2. Be careful and comprehensive during the inspection;

3. When taking samples, be careful that the shore is slippery and do not go into deep water;

4. When taking samples, do not touch the water directly with your hands. It is best to wear gloves.

Field trips

During the inspection, first look at what kind of environment is there around the water area? Is there any wastewater discharge?

What is the color of the water? Are there animals and plants in the water? Are there any pollutants in the water?

Finally, take a bottle of water sample and bring it back to school for inspection and observation.

Further observations on the collected water samples

Let the water sample stand for a period of time and see if any impurities precipitate. What are the impurities?

Use a microscope to see if there are any tiny organisms in the water that are invisible to the naked eye?

Fill out a report after observation.

How to manage the natural waters in your hometown?

My advice:

Start with yourself and don’t throw garbage into the creek;

Educate those around you about protecting our creeks;

Spontaneous organizations to clean up litter in creeks;

Recommend to the government to strengthen the management of creeks.
