AC9S5U02 Year 5 Science

This Content Descriptor from Year 5 Science provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

describe how weathering, erosion, transportation and deposition cause slow or rapid change to Earth’s surface

Elaborations

• 1 identifying types of weathering caused by mechanical means such as by wind abrasion, cycles of extreme heat or cold, and frost wedging; and biological means such as by plants and tree roots
• 2 exploring how erosion can be caused by moving air or moving water and how substances such as surface soil are relocated, and identifying examples of erosion on a local or regional scale
• 3 analysing the difference between weathering and erosion and comparing the timescales over which these processes can occur
• 4 modelling the effects of erosion on a simulated landscape and exploring factors that mitigate its effects
• 5 investigating how humans have changed local landscapes and predicting the effect these changes might have on rates of erosion
• 6 considering how First Nations Australians are impacted by the rapid erosion of sand dunes and the resulting effect of saltwater on culturally significant freshwater swamps
• 7 considering the effects of significant rainfall, such as a monsoon, on the transportation and deposition of river sediments in the Asia-Pacific region
