We
think that the plant watered with the acid rain will not grow as well as
the plant watered with distilled water.

Earlier
in the year we did an experiment to determine the effect of acid rain on
limestone buildings. We used chalk to represent the buildings.
Distilled water was sprayed on one piece of chalk while a solution of one
part distilled water and one part vinegar was sprayed on another piece
of chalk. The results were astonishing! The chalk sprayed with
the acid rain ( one part distilled water and one part vinegar) dissolved
and ended up an ugly lump on the bottom of the glass. We wondered
what the effect of acid rain would have on plants.
To prepare for the experiment we purchased two similar plants. Both were pathos plants. We placed both the same distance from the window and gave each the same amount of liquid. One was sprayed with distilled water while the other was sprayed with the acid rain solution. Pictures were taken twice a week usually on Mondayís and Fridayís Very quickly we observed differences between the two plants. The one sprayed with distilled water continued to grow. It stayed green. The one sprayed with the acid rain solution started to droop. Some of its leaves turned yellow. Later they got black spots. Eventually, the leaves were all collapsed and leaned on the table top. We concluded that acid rain was not good for plants. |

1. Two similar sized pathos plants were purchased. 2. Both were placed the same distance from the window. 3. Both plants received the same amount of liquid. 4. One plant was watered with a mixture of one part distilled water and one part vinegar to represent acid rain. 5. The other plant was watered with distilled water. 6. Photographs were taken twice a week. |

When
the plants were purchased they were the same size measuring ten inches
each. By the second week the distilled water plant measured ten and
one fourth inches while the acid rain plant only measured eight and one
half inches. A few of the leaves started to turn yellow. By
the third week the distilled water plant measured ten and one half inches
while the acid rain plant measured only six inches. Its leaves drooped
down. More leaves were yellow and black spots appeared on several.
By the fourth week the distilled water plant measured ten and one half
inches while the acid rain plant measured only four and a half inches.
It looked lifeless.

We found that the plant that received the distilled water grew normally. The plant watered with acid rain didnít continue to grow. Acid rain is not good for plants. | |
