2.  How do the pH, phosphorus, and potassium levels of soil compare in three different areas of human contact? Key Question

3. Hypothesis  Pond  Will have low results from tests  Water from pond my effect results  Pathway  Will have the worst results from tests  No helpful human contact  Football Field  Will have the best conditions  High results for all tests

4. Background Pond Mostly in shade Mostly in shade No human contact No human contactPathway Sunny area Sunny area A lot of human contact daily A lot of human contact daily Football Field Fertilized Fertilized Most human contact Most human contact

5. Materials  pH/Potassium/Phosphorus soil test kit (Separate)  Thermometer  3 containers (samples)  Spade  Test tube rack  Clip Board  Goggles

6. Procedures 1.Gather our materials. 2.Get soil (dig down 4 inches to get good samples) 3.Take temperature of soil in all three sites. 4.Once we have the soil follow the written procedures for pH, Phosphorus, and Potassium. 5.Record the data. Clean up.

11. Our results (football field)  Phosphorus  Easily different  Change maybe from human contact  pH  Little difference  Maybe from weather conditions  Potassium  Difference in results  Maybe fertilizer effected results Football Field Weather Phosphoru spHPotassium Rainy50-1007120-200 1-50 1-5071-120 Rainy50-10061-120 Clear<16.5120-200 1-50 1-505120-200 Clear>100 7 120-200 Cloudy 1-50 1-5071-120 Cloudy50-1007<1

13. Explaining our results  Reasons for location  Effects of Weather  Reason for differences

14. Interpretations of Results  Pond  pH a little low, phosphorus low, potassium good  Football Field  pH is good, phosphorus is good, and potassium ok  Pathway  pH a little low, phosphorus low, potassium good  Football field seemed to be in the best conditions.

15. Discussion Conclusion Focus on separate tests. Shorten time. Organizing work better.
