at the time outside the classroom I had been involved in a number of research discipline wastewater profession at pig farms, studying the properties of the soil, and are come to some localities in the city to measure and digging soil profiles. Also I have been a teacher for viewing some of the waste water treatment tank through the model in the laboratory. I find it very rewarding and it has given me a deeper knowledge about the school environment as well as the environmental status of water, soil today.
