Experimental Design Diagram: pH level change in soil over time           My question: How does the pH level in the soil change over time? Research: Works Consulted Gibson, Mary Jo. “Understanding Soil pH.” Penn State Extension , 28 June 2023, https://extension.psu.edu/understanding-soil-ph. Accessed 6 September 2025. United States Department of Agriculture. Inherent Factors Affecting Soil pH Soil pH Management , May 2014, https://www.nrcs.usda.gov/sites/default/files/2022-10/Soil%20PH.pdf. Accessed 6 September 2025. There are various influences that cause effects on the pH levels in soil including the texture of the soil, the climate, time of formation, and much more. In wet warmer climates pH levels will likely go down over time due to precipitation, but in dryer areas the pH levels may very well stay the same. Soil containing clay often takes longer to change in pH level while soil with sand is faster. The pH level is also affected by the numb...

Field Study #1

Field Notes:  Date: September 6, 2025 Time: 1:59 pm Temperature: 61˚F Conditions: Partly cloudy, somewhat windy Sunrise: 7:04 am Sunset: 7:58 pm Length of day: 12 hours and 54 minutes Sounds: I heard cicadas, birds chirping, wind, and the leaves rustling.  Sights: I saw trees, bushes, and algaes, along with other plants and dead leaves. Changes: None (First Visit) Notices: Something I noticed that I found was really interesting was that the ground where I took my pH test had a pretty thick layer of leaves. I thought that was interesting, as the leaves were about an inch thick and pretty dense until the soil. Questions: I wonder if the amount of dead leaves on the ground affect the pH levels at all? I noticed that the ground around the pond was really wet. There was this cool bug that was crawling on me while I was there. There was a bird flying around, so I took a picture of it. I saw a few frogs jump into the water, but I was not able to get a good picture. This is the pictur...

Field Study #3

  Field Notes:  Date: October 11, 2025 Time: 1:30 pm Temperature: 63˚F Conditions: Cloudy, no rain Sunrise: 7:53 am Sunset: 7:07 pm Length of day: 11 hours and 14 minutes Sounds: I heard cicadas, birds chirping, someone mowing their yard nearby, sticks breaking Sights: I saw trees, bushes, and algae, along with other plants and dead leaves. Changes: I noticed a lot of change today. The leaves are changing color and it is getting a lot colder. Notices: I noticed that there were a lot fewer bugs and spiders. I was kind of surprised by the lack of bugs, as usually I see tons of them. Questions: I wonder what will happen to the algae when the pond starts to freeze over. This is the picture that I take every time. I took a picture of these leaves last time because I thought they looked cool, but I think that this plant's leaves might turn purple in the fall, because I saw an increase of purple leaves. I thought this was a good picture of the leaves changing color. Not much was happ...
