AC9S2U03 Year 2 Science

Content descriptor recognise that materials can be changed physically without changing their material composition and explore the effect of different actions on materials including bending, twisting, stretching and breaking into smaller pieces

Elaborations

• • Elaboration 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, or folding paper to make it fly
• • Elaboration manipulating materials such as paper or fabric, and determining ways they can be physically changed by scrunching, twisting or bending, or broken into smaller pieces by cutting, tearing or crushing
• • Elaboration 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
• • Elaboration exploring how First Nations Australians make physical changes to natural materials to produce objects such as bowls, baskets and various fibre crafts
• • Elaboration 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
