Acid Rain Plants by xdKhg06

									Experiment Background: This experiment will take two weeks to complete. You will be discovering how
acid rain has a direct effect on plants. Keep in mind what you know about acid rain and the fossil fuels
that create it.


Materials:     4 cups or jars
               distilled water
               white vinegar
       measuring cups
       stirring spoon
       2 cuttings of a philodendron plant
       2 cuttings of a begonia or coleus plant
       lab notebook for recording daily
       scientific process form


Lab Instructions:     1. Begin the Scientific Process Form
               2. Put one of the following labels on each jar
                      *water philodendron
               *acid philodendron
               *water begonia (or coleus)
               *acid begonia (or coleus)
       3. Pour one cup of distilled water into the water-philodendron and water-begonia
       4. Pour one cup of vinegar/water mixture (2 cups distilled water and 1 teaspoon
       vinegar) into the acid-philodendron and acid-begonia cups
       5. Put one philodendron cutting into each philodendron labeled cup, covering the
       stem and part of the leaf with the liquid
       6. Put one begonia cutting into each begonia labeled cup, covering the stem and
       part of the leaf with the liquid
       7. Set the cups where they are not likely to be spilled and where they will
       receive sunlight.
       8. About every two days, check to be sure that the plant cuttings are still in the
       water or vinegar/water. You may need to add more liquid if the cups become dry.
       9. Every day record what you see happening in you lab notebook.
       Compare the new root growth of each plant in distilled water with the new root
       growth of its corresponding plant in acid water. Don’t forget to record the results
       in you lab notebook.
       10. After two weeks complete the Scientific Process Form – make sure that you
       draw conclusions from the lab results and extend you new knowledge to our
       bigger topic of how acid rain affect our world and how we live.
Criteria:            1. All containers should be labeled correctly.
                     2. All plant containers show evidence of directions being followed
                     2. 2 weeks of observations should be recorded in the lab notebook.
                     4. The Scientific Process Form is completed
                     5. The Results and Conclusions sections of the Scientific Process Form should
                     show conclusions drawn from the results, and conclusions should show ideas
                     of how acid rain affects our world and how we live
