Separation by Filtration and Sieving - Results Tables

The set of experiments outlined is designed to investigate the efficacy of different filtering equipment and materials. One aspect of the study compares the similarities and differences between a colander and a sieve, two common kitchen tools used for separating mixtures. This comparison aims to understand how each tool functions in the context of filtration and what distinguishes one from the other in terms of their effectiveness. Additionally, the experiments explore whether various grades of filter paper have an impact on the filtration process. This is measured by recording the time taken for a liquid to pass through filter papers of three different grades, with multiple attempts made to ensure reliability, and an average time calculated for each grade.

Another part of the investigation looks at the effectiveness of filtration by examining how well sand is removed from water. This is quantified by measuring the initial and end mass of sand, and noting whether any sand remains in the water post-filtration, indicated by a simple 'Yes' or 'No'. This process is repeated with different initial masses of sand to assess the consistency of the filtration method. The study also includes common household filtering materials such as teabags and coffee filters, presumably to compare their filtering capabilities against more traditional laboratory filter papers. The comprehensive results tables are designed to capture the outcomes of each test, allowing for a clear analysis of the performance of each filtering method and material.
