Properties of everyday materials - Worksheet

This worksheet is designed to help students explore and understand the properties of various everyday materials. Students are asked to consider a range of materials including iron, aluminium, wood, plastic, glass, sugar, flour, salt, bread, brick, wool, and cotton. For each material, they are to rate its hardness on a scale from 1 to 10, and then determine whether it is soluble, transparent, and whether it can conduct electricity. These attributes will give the students insight into the physical characteristics of the materials and how they might be used in different contexts.

Additionally, the worksheet prompts students to think critically about the permanence of changes in materials. They are asked to identify which of the listed materials can be reverted to their original form after a change. This encourages them to consider the concepts of reversible and irreversible changes. To deepen their understanding, students are also tasked with devising an experiment to test which materials can and cannot be changed back to their original state. This practical approach to learning not only reinforces theoretical knowledge but also hones their scientific inquiry skills.
