Experiment Background: You have read the book Going Green. It discusses acid rain and how fossil fuels cause this environmental problem. You completed the Acid Rain and Plants experiment last week. Today you will be developing, in your cooperative group, an experiment that investigates the acid rain effects on metal and stone (buildings and monuments). It should take ten day to see final results. Materials: The following materials will be made available to you. 6 cups or jars distilled water white vinegar lemon juice measuring cups stirring spoon lab notebook for recording daily scientific process form 2 clean copper pennies (dated before 1993) plastic wrap pieces of marble pieces of limestone Lab Instructions: You and your cooperative group need to create the lab instructions for this lab. Use the attached form. Make sure you look at the cooperative group work evaluation so you know how your group work will be assessed. Criteria: 1. All containers should be labeled correctly. 2. Developed a step-by-step plan for the experiment. 3. Lab Questions are correctly answered. 4. Lab is correctly conducted based on original plan. 5. 2 weeks of observations should be recorded in the lab notebook. 6. The Scientific Process Form is completed. 7. 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.

(Lab Question Sheet) Some of the form is completed accurately Relationships are not drawn between results and conclusions No ideas of acid rain affects on the environment are evident Most of the form is completed accurately Relationships are drawn between results and conclusions All of the form is completed accurately Relationships are thoroughly drawn between results and conclusions Ideas of acid rain affects on the environment are evident Gave 0 solutions Gave 2-3 Gave 4-5 solutions X3 X2 X4 X4
All students are sitting together All members are taking turns talking Heads are nodding Positive, encouraging comments are made All members help to create the experiment plan YES NO LAB PROCEDURE: You must have at least 10 steps in your procedure. 1. 2. 3. 4. 5. 6. 7. 8.
9. 10. 11. 12. 13. 14. 15. Answer the following questions after you have completed the lab. 1. What change, if any, took place in the water jar after 5 days? Penny: Marble: Limestone:
2. What change, if any, took place in the vinegar (or lemon juice) jar after 5 days? Penny: Marble: Limestone: 3. What change, if any, took place in the water jar after 10 days? Penny: Marble: Limestone: 4. What change, if any, took place in the vinegar (or lemon juice) jar after 10 days? Penny: Marble: Limestone:
5. Based on your findings, how does acid rain affect our world? 6. Based on the experiments on acid rain and your readings, what are some things you could do about the acid rain problem? Name Title of Experiment
QUESTION: What do you want to find out? HYPOTHESIS: What do you predict will happen? MATERIALS: What items do you need in order to do this experiment? PROCEDURE: How will you find out? (number step-by-step) RESULTS: What happened during this experiment? CONCLUSION: What did you learn from this experiment?
