Problem: What is the effect of gasoline fumes on bean plant growth?
Hypothesis: If the bean plants are exposed in the presence of gasoline fumes for a longer period of time, then the plants will die more quickly.
1. Place ten bean plants in each of five Rubbermaid clear plastic containers. 2. Let the bean plants sit for one week without being manipulated. 3. Leave the first container alone without manipulation. 4. Expose the second container to gasoline fumes for a fifteen minute period. 5. Expose the third container to gasoline fumes for a twenty minute period. 6. Expose the fourth container to gasoline fumes for a twenty-five minute period. 7. Expose the fifth container to gasoline fumes for a thirty minute period. 8. Record the results in a data table once a week.
9. Repeat steps 3-8 once a day for one month.
Data Analysis: Every week we will make qualitative and quantitative observations and record them in a data table.
