Changing Materials - Results Tables

The "Changing Materials" activity is a practical exercise designed to explore the physical properties of various materials. It involves a series of tests to determine how different objects respond to certain actions. A results table is used to record the outcomes of these tests. The objects being examined include everyday items such as bags, foil, cling film, erasers, rulers, bottles, soda cans, paper, pencils, pens, coins, bands, and cardboard. Each object is made from a distinct material which will react differently when subjected to the following actions: twisting, bending, stretching, squashing, snapping, and tearing.

This structured investigation allows students to gain hands-on experience with the concept of material properties. They will systematically apply the six actions to each object and note the material's reaction in the results table. For instance, they may observe whether a bag can stretch without breaking, or if a soda can will squash under pressure. The aim is to understand the limits and capabilities of different materials when they undergo physical changes. The recorded observations will help students to compare the resilience and flexibility of materials, providing a clear visual representation of how certain materials can be manipulated in various ways without being damaged, while others may break or tear easily.
