AbstractDifferent pH level may affect the growth and development of the plants. Certain key words include: pH level‚ germination‚ acidity‚ osmosis and diffusion. This experiment examines the effects of different pH level of vinegar on the growth of bean plants. Materials used in this experiment consist of: water (pH 6)‚ vinegar with the pH level of 3‚ 4 and 5 (each one were made before experiment)‚ beans‚ soil‚ and pots. Eight bean plants were planted‚ two were watered with pH 6 and the other ones were
