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

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

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

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

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.

Our Results (pond) Phosphorus No change from weather No change from weatherpH Some differences Some differences Could be from leaves around Could be from leaves aroundPotassium No change from weather No change from weather WeatherPhosphoruspHPotassium Rainy < Rainy < Rainy < Clear < Clear < Clear < Cloudy < Cloudy

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 Rainy Rainy Clear< Clear> Cloudy Cloudy <1

Our Results (Pathway) Phosphorus No difference No difference Weather had no effect Weather had no effectpH Little change Little changePotassium Small change Small change Not taken care of Not taken care of Pathway WeatherPhosphoruspH Potassium Rainy< <16>200 <15>200 Clear< < < Cloudy< <

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

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.

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