Acid Rain

Acid Rain in Plants

Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic. Pollution is the cause of all acid deposition.

Hypothesis: We believe that if we increase the acidity of water with lemon, the rate of the plants’ growth will decrease. We believe that for each 1 pH increase in the acid solution the plants will grow less than normal. We believe all plants will survive.

  • Independent Variable: Type of water // contaminant and pH given to the plant.
  • Dependent Variable: Height of the stem of the plants.
  • Controlled variables: Type of soil, amount of soil, amount of water, same exposure to sunlight and air.
