the observable properties of matter (solids, liquids and gases) can be explained by modelling the motion and arrangement of their particles; mixtures (including solutions) can be formed by combining 2 or more different substances

• using role-play to model the arrangement and motion of particles in solids, liquids and gases, and exploring, with guidance, ideas about what exists between particles
• using a large plastic syringe to observe the compressibility of air compared with that of liquids, and observing a virtual demonstration of coloured gases being compressed and providing an explanation for the change in colour intensity
• exploring examples that demonstrate that gases have mass, such as blowing air through straws to move objects and using a balance to compare an empty balloon to one filled with air
• investigating mixtures by setting up sensory bins with a variety of materials that can be sorted and mixed, such as beads, rice, pasta, buttons, coins and plastic lids
• identifying common examples of mixtures and solutions in their daily lives
• making lemonade (a solution) by dissolving lemon juice and sugar (solutes) into water (a solvent)
• recognising Aboriginal and/or Torres Strait Islander Peoples’ knowledges and understandings of solids, liquids and gases, and how these knowledges are applied in a range of processes and practices, including the use of ochres and in cooking
