BIODIVERSITY PROJECT
Performance Outcome: Asks specific testable scientific questions about a significant global science issue. Questions build on an evaluation of prior interpretations of evidence, a model, engineering design, or the premise of an argument.
Description: In my freshman Biology class, we were tasked to explore the biodiversity of three separate spots around Austin. These include Inks Lake, Pace Bend, and Mansfield dam. Each group found a series of data that were factors that directly affected the biodiversity of each area. We used samples of water and different sets of kits to determine the phosphate levels, nitrate levels, salinity levels, and PH levels. Each of these were components that lead to the different levels of diversity at each location. Based on the data my group collected Inks Lake had the most biodiversity out of all three locations. This can be explained by the low level of phosphate, unlike at Pace Bend and Mansfield Dam. Mansfield had by far the lowest quantity of biodiversity because the phosphate amount was 8.04 which is at least 7ppm over the amount of phosphate at the other two places. Meaning Pace Bend has a higher phosphate level than Inks Lake but there was still some biodiversity. Biodiversity is important in every ecosystem because it boosts productivity and every species plays an important role. This project made me able to construct specific testable scientific questions about a significant global science issue, including; How do the levels of phosphate around the world affect the ecosystems wildlife and productivity?

Reflection: The purpose of this project was to teach us that elevated or lowered levels of an element in an ecosystem can negatively or positively affect the animals and other living things living there. This project helped me understand that the environment is delicate and with one change to it and no adaption it could have a devastating impact. I think the levels of phosphate is a pressing issue that should be addressed. The increased levels of phosphate cause algae and other plants to grow rapidly taking oxygen from the aquatic life causing them to suffocate and die. In order to keep a stable level of phosphate and other elements like nitrates, salinity, and PH we can try and prevent excessive runoff and keep manure and fertilizers out of the waterways.
