materials can be changed physically by different actions without changing their material composition, including by bending, twisting, stretching, crushing, squashing and breaking into smaller pieces

• exploring how materials can be physically changed to suit a particular purpose, such as twisting strands of cotton or wool together to make the thread stronger, and folding paper to make it fly
• manipulating materials such as paper and fabric, and determining ways that these can be physically changed by scrunching, twisting or bending, or broken into smaller pieces by cutting, tearing or crushing
• crushing a stick of chalk into a powder, comparing the properties of the stick and the powder, and discussing whether it is still the same material
• investigating how Aboriginal and/or Torres Strait Islander Peoples make physical changes to natural materials to produce material culture, for example in fibre technologies (such as basketry and fishing lines), pigments (such as ochre and medicines) and timberworking (such as working saplings to form boundary markers)
• creating an ‘odd one out’ game by providing samples of the same material that has been physically changed in different ways and one sample of a different material, and challenging other students to identify the odd one out
