UNITS OF WORK STAGE Three
Everything around us is made of matter. Matter commonly exists as solids, liquids or gases. Substances can be classified as a solid, liquid or gas based on their observable properties and behaviours. Matter can be changed from one state to another by adding or removing heat. This can be seen in everyday situations such as a liquid turning to a solid when water is put in the freezer, a liquid turning to a gas when water is boiled in a kettle and a solid turning to a liquid when ice cubes are left in the sun. |
In order for species of plants and animals to survive in particular environments, they have had to adapt to the conditions of the environment in which they live. The adaptation to environmental conditions occurs over many generations. In order to survive in the environments in which they live, plants and animals develop both behavioural and structural adaptations. |
Australia is one of the world's driest continents, yet its citizens use more water per capita than anyone else. |
Australia experiences extremes of weather that vary across the continent and impact our lives, the environment and the Earth’s surface. Weather extremes have many consequences. Understanding these extremes of weather and the possible implications for human survival may help reduce their impact. |
Weathering is the natural force that wears down objects by the elements (temperature, wind, water, gravity) in the environment.
In this unit students will explore the differences between weathering and erosion before making an in-depth study of erosion. Erosion in the local environment is investigated. Students create models of water erosion with the teachers’ guidance. Through a guided inquiry activity, students design and create a wind erosion model. The culminating activity is the proposal of a remedial land care program to combat erosion of farming soils......
