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 Criteria 1 3 5 Weight Containers Labeled Few are labeled Some are labeled All are labeled Directions were Directions were Directions were followed not followed followed Data Recorded Little data are Most data are All data are ___X2 = recorded recorded Recorded _____/10 Scientific Process Form Some of the form Most of the form All of the form ___X2 = Completion is completed is completed is completed accurately accurately accurately _____/10 Scientific Process Form Relationships are not Relationships are Relationships are ___X4 = – Results and drawn between results drawn between thoroughly drawn Conclusions Sections and conclusions results and between results and _____/20 conclusions conclusions Conclusions show ideas No ideas of acid rain Ideas of acid rain ___X4 = of how acid rain affects affects on the affects on the our environment and environment are environment are _____/20 how we live evident evident TOTAL SCORE _____/70 = ______% Name _______________________________ Title of Experiment ______________________________ QUESTION: What do you want to find out?
