Example of investigatory project using banana peel?

One example of an investigatory project using banana peels is studying their potential as a natural alternative for water filtration. This project could involve testing the effectiveness of banana peels in removing impurities from water through a series of filtration experiments. By analyzing the results, researchers can determine the feasibility of using banana peels as a sustainable and cost-effective water purification method. This project combines elements of chemistry, environmental science, and engineering to address a real-world problem with a creative solution.
