Experimental Procedure

  1. Make two sets of solutions daily.   The first solution consists of rainwater, which is collected from the environment in a rain barrel. Pour two cups (500 ml) of rainwater into a glass beaker and label it rainwater. Pour two cups (500 ml) of rainwater into a different glass beaker and label it acid rain.     
  2. In the beaker labeled acid rain, pour five and a half teaspoons of white vinegar into the two cups (500 ml) of rainwater.  
  3. Use the stirring rod to mix the acid rain solution.
  4. Check the pH of the resulting acid rain solution with a pH indicator. Make sure the solution has a pH of 3.
  5. Categorize the plants into two groups of eight. Label one group acid rain solution plants and the other group rainwater plants.
  6. Place the plants on a sturdy table where they will receive adequate sunlight.
  7. On a daily basis, hydrate all plants within the experimental and control group. Measure one eighth cup of rainwater from the rainwater beaker and pour it on the plants labeled rainwater.   Measure one eighth of a cup of the acid rain solution from the acid rain beaker and pour it on the plants labeled acid rain solution.
  8. Take pictures of the plants daily.
  9. Observe data and record results in the laboratory notebook daily.
  10. Repeat this experiment multiple times to ensure accurate results.

Results

Data and Analysis

Trial 1: December 26, 2010 through January 1, 2011

Trial 2: January 2, 2011 through January 8, 2011

Trial 3: January 9, 2011 through January 15, 2011

Trial 1
December 26, 2010

Both the rainwater and acid rain plants are healthy and vibrant. The pigmentation of both sets of plants is dark green.

December 27, 2010

The rainwater plants exhibit no change. The flowers are intact and erect and the leaves are dark green. The acid rain plants show slight variations from the previous day. Some of the leaves showed signs of distress. 

December 28, 2010

The rainwater plants exhibit no noticeable change in their appearance. The flower petals are intact and the leaves are dark green. The acid rain plants exhibit a higher level of distress. There is a slight discoloration in the pigmentation of the leaves. The colors of the leaves are fading to a light green.

December 29, 2010

The rainwater plants are upright with flowers petals intact. They exhibit little to no change. The acid rain plants show signs of wilting. Many plant leaves are yellow in appearance and a few have light brown at edges. 

December 30, 2010

Overall, the rainwater plants are healthy. The pigmentation of the leaves is dark green. Some slight wilting of the flower petals is evident. The majority of the flower petals in the acid rain plants are no longer present. Withering of the plants has continued, along with yellowing and browning of the leaves.

December 31, 2010

The flower petals of some of the rainwater plants are wilting. The plant leaves are still dark green in pigmentation and healthy in their physiological appearance. The stems of many acid rain plants have a yellow appearance. Drooping and wilting is prevalent and the overall health of the plants is deteriorating. The browning of the leaves continues.

January 1, 2011

The rainwater plants exhibit a healthy appearance. The pigmentation of the leaves is dark green and a few flower buds have appeared. The acid rain plants exhibit an extremely unhealthy appearance. The plants are shriveled with several dead leaves. The plants exhibit a severe dehydrated and malnourished appearance.

Trial 2
January 2, 2011

The rainwater and acid rain plants are healthy in appearance with dark green pigmentation.

January 3, 2011

The rainwater plants show no change in appearance. The flowers exhibit an upright posture and are blossoming with life. The acid rain plants exhibit an insignificant physiological change. The leaf pigmentation is dark green and the flower petals are intact.

January 4, 2011

The rainwater plants have a fresh appearance. The pigmentation of the leaves is dark green and the flowers are vibrant in appearance. The acid rain plants exhibit a slight discoloration in the pigmentation of their leaves. The color of the leaves changed to a lighter shade of green.

January 5, 2011

The rainwater plants are healthy in their physiological appearance. The flower petals are upright and intact. The leaves of the acid rain plants exhibit wilting, yellowing, and browning.

January 6, 2011

The rainwater plants maintained a healthy physiological appearance. The pigmentation of the leaves is dark green. Some flower petals showed signs of wilting. The majority of the acid rain plants have no flower petals. Wilting of the plants is widespread and the leaves continue to turn yellow and brown.

January 7, 2011

The rainwater plants are healthy in appearance. There is a slight progression in the wilting of the flower petals. The coloration of the leaves remained dark green. The overall health of the acid rain plants is deteriorating. Both the stems and the leaves of the acid rain plants are yellowing, drooping, and withering in their physiological appearance. The leaves continue to turn brown.  

January 8, 2011

The rainwater plants remained healthy in appearance. The foliage is lush and dark green. Some plants have flower buds. The acid rain plants exhibit an unhealthy appearance. The foliage is shriveled, dehydrated, and on the brink of death.

Trial 3
January 9, 2011

The rainwater and acid rain plants are healthy with dark green foliage and vibrant flowers. 

January 10, 2011

The rainwater plants are healthy in physiological appearance. The leaves have a dark green pigmentation and all flowers are upright. There is a small change in the physiological appearance of the acid rain plants. The foliage of the plants is not as vibrant as the previous day.

January 11, 2011

The rainwater plants are similar in appearance to the previous day. There is no noticeable change in their physiology. The pigmentation of the leaves of the acid rain plants is fading. The foliage changed from a dark green pigmentation to a shade of light green.

January 12, 2011

The rainwater plants are upright in position with flower petals intact. They have an overall healthy appearance. The acid rain plants are showing signs of physiological distress. The plants leaves are yellowing, browning, and wilting.

January 13, 2011

The rainwater plants are healthy with lush green foliage. A few flower petals are wilting. All flower petals of the acid rain plants are no longer present. The leaf pigmentation continues to turn yellow with slight browning on the edges. The acid rain plants show an increase in wilting.

January 14, 2011

The rainwater plants maintained a healthy outward appearance with wilting of some flower petals. The leaves are dark green in pigmentation and a few new flower buds are present. The stems of the acid rain plants are becoming yellow in appearance. The health of the acid rain plants are drastically deteriorating with drooping and wilting prevalent. The browning of the leaves continue.

January 15, 2011

The rainwater plants are healthy in appearance. The pigmentation of the leaves remains dark green and the majority of the flower petals are intact. The acid rain plants have undergone dramatic physiological changes. The plants are unhealthy in their appearance. The leaves are shriveled, withered, and dried. The coloration of the plant stems are light yellow and the majority of the leaves are brown.
