Core Skills Analysis
Science
Merrick researched the difference between point and nonpoint source pollution, learning that point sources are single, identifiable origins like a factory pipe, while nonpoint sources are diffuse, such as runoff from agricultural fields. He then designed an experiment to filter water, applying concepts of physical filtration and contaminant removal. Finally, Merrick explored water distillation, recognizing how phase changes can separate pure water from dissolved impurities. Through these steps, he connected theory to practical methods for improving water quality.
Mathematics
Merrick used measurement and data‑analysis skills while planning his water‑filter experiment, calculating volumes of water, estimating filtration rates, and recording results in a table. He applied ratios to compare the effectiveness of different filter materials and used basic graphing to visualize contaminant reduction over time. These activities reinforced his ability to interpret quantitative data and draw conclusions from numerical evidence.
Language Arts
Merrick conducted research on pollution sources and water distillation, summarizing his findings in written notes and citing reliable sources. He organized his information into logical sections—definition, cause, solution—demonstrating expository writing structure. By explaining the experiment design and results, he practiced clear technical communication and precise vocabulary related to environmental science.
Social Studies
Merrick examined how point and nonpoint source pollution affect communities, identifying economic and health impacts on local populations. He considered policy implications, such as regulations for industrial discharge versus best‑management practices for agriculture. This broadened his understanding of the interplay between human activity, government action, and environmental stewardship.
Tips
1. Extend the water‑filter experiment by testing natural materials (sand, charcoal, plant fibers) and comparing their efficiencies. 2. Conduct a field survey of a nearby stream or pond to identify visible signs of point and nonpoint pollution, then map findings on a simple GIS‑style grid. 3. Have Merrick write a persuasive letter to local officials advocating for a specific pollution‑reduction measure, using data from his experiment as evidence. 4. Create a mini‑documentary where Merrick narrates the water‑distillation process, integrating graphics and interviews with family members about why clean water matters.
