Testing Materials - Results Tables

The provided text outlines a series of tables used to classify various materials based on their physical properties. The first table categorises materials as either transparent or opaque. Items such as a plastic bottle, exercise book, desk, floor, window, foil, clingfilm, and plasticine are evaluated to determine their ability to allow light to pass through, hence identifying them as transparent or blocking light, thus being opaque. This classification helps in understanding the visual and light transmission characteristics of different materials.

The second table focuses on the waterproof nature of materials. It examines objects like a bottle, book, fabric, floor, window, foil, and clingfilm to see what happens when they come into contact with water. The goal is to ascertain whether the material prevents water from passing through, thereby classifying it as waterproof, or if it allows water to seep through or get absorbed. The third table assesses the absorbency of various items, including a sponge, tissue, paper, kitchen roll, toilet paper, and dish cloth. It checks whether these items can absorb some water or even up to half a cup, providing insight into the capacity of these materials to soak up liquids. These tables are instrumental in determining the suitability of materials for different uses based on their transparency, water resistance, and absorbency.
