SOIL CONTAINS AIR










                 ➢Fill half a jar with dry garden soil and put it down.







                 ➢Gently pour water on the soil until the jug is full.








                 • When water is poured over soil, air bubbles start


                    forming.








                 • Soil contains air, trapped between its particles.








                 • When water is poured, this air escapes in the


                    form of bubbles.
