Is there control in this experiment ? Explain why or why not and please mention the Independent variable and dependent variable in the answer. Thanks.

1. Observation The trash smells. 2. Explanation Decaying biological material causes the trash to smell. 3. Test (independent variable) Add food scraps to one trash can along with non-food materials, such as plastic, cardboard, paper, and tin. To a second trash can, add only non-food materials, such as plastic, cardboard, paper, and tin. Observe the smell of each trash can over a few days. 4. Prediction (dependent variable) The trash can containing food scraps will smell more than the trash can with non-food materials. 5. Hypothesis If decaying matter causes the trash to smell, then removing food scraps from the trash will decrease the odor that it produces
