** First Rough Draft ** We took 50 5oz Dixie Cups, and used 10 of each for our different groups: cigarette butts, motor oil, fast food wrappers, the control, and a mix of all the pollutants. For the control, we filled the cup with 75 mL of soil. The control cups had lines along the top. For the Motor Oil we took 750 mL of soil and added 100 mL of motor oil and mixed it. Then we put 75 mL of the soil into 10 Dixie Cups that are labeled with 2 lines on the top. For the cigarette butts we added 30 cigarette butts to 750 mL of soil and mixed it. Then we put 75 mL of the soil into 10 Dixie Cups labeled with 3 lines on the top. For the fast food wrappers we took 750 mL of soil and added torn up wrappers (1 taco bell soft taco wrapper, a McDonalds breakfast burrito wrapper, and an empty hot sauce packet) and mixed it with the soil. Then we put 100 mL of the soil and wrappers into 10 Dixie Cups labeled with 4 lines. For the mix, we took 750 mL of soil and mixed it with torn up fast food wrappers (a Taco Bell soft taco wrapper, a used napkin, and a small Wendy's fry container). We added 30 more cigarette butts and 100 mL of motor oil to the bag and mixed it all up. Then we put 75mL of the mix into 10 Dixie Cups and marked a continous line around the top. Then we let the cups sit for 18 hours and added 1 sunflower seed to each cup and watered it with 20 mL of water every other day. Every 7 days we measured the plants with a ruler and recorded it in the results table.

**Second Rough Draft** Jo added this- To begin our experiment, we assembled 50 5oz. Dixie cups and appropriately labeled them (in groups of ten): cigarette butts, motor oil, fast food wrappers, mix, and control. We then added 75 oz. of pure soil to each cup in the control group and set them aside. Next, we took a large Ziploc bag, filled it with 750 oz. of soil and added 30 cigarette butts into it. We thoroughly mixed the soil and the cigarettes together and let it sit for 10 minutes. In another large Ziploc bag we added 750 oz. of pure soil and mixed 100ml of motor oil into it for 5 minutes; we also let that sit for 10 minutes. We then filled another large Ziploc bag with 750 oz. of soil and mixed in torn up pieces (about 0.5 in. in diameter) from one Taco Bell soft taco wrapper, a used fast food napkin, a Breakfast Burrito wrapper, and an empty hot sauce packet. This was also thoroughly mixed and set aside for 10 minutes.

Sam added this- For the mix, we took 750 mL of soil and mixed it in a Ziploc bag with torn up fast food wrappers (a Taco Bell soft taco wrapper, a used napkin, and a small Wendy's fry container). We added 30 more cigarette butts and 100 mL of motor oil to the bag and mixed it all up. After letting it sit for ten minutes, we put 75mL of the mix into 10 Dixie Cups. After we did that, we let the cups sit, and after 18 hours added 1 sunflower seed to each cup and watered it with 20 mL of water every other day. Every 7 days we measured the plants with a ruler and recorded it in the results table.
