We celebrated the subject Association on 3/2/2021.
I made a still model of air pollution.We know that with the devlopment of facilities ,there is also increase in the pollution level.Car emissions,chemicals from factories,dust etc causes the pollution of air .
Then I prepare a working model of water purifier.
