Nature and development of science

This Content Descriptor from Year 7 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.

Content Descriptor

explain how new evidence or different perspectives can lead to changes in scientific knowledge

Elaborations

• exploring how scientists are re-examining the relationships between organisms to refine the classification of species as they discover new information or interpret evidence in new ways
• investigating how the land management practices of First Nations Australians inform contemporary management of the environment to protect biodiversity
• investigating how First Nations Australians’ traditional ecological and zoological knowledges inform sustainable harvesting practices of certain species, such as dugongs and turtles
• researching developments in the understanding of astronomy, such as the predictions of eclipses and the calculation of the length of the solar year by Abu Abdallah Mohammad ibn Jabir ibn Sinan al-Raqqi al-Harrani al-Sabi al-Battani in the 10th century
• investigating how aeronautical engineers’ understanding of the nature of the forces acting in flight have led to changes in the design of aircraft

Year 7 Science Achievement Standard

By the end of Year 7 students explain how biological diversity is ordered and organised. They represent flows of matter and energy in ecosystems and predict the effects of environmental changes. They model cycles in the Earth-sun-moon system and explain the effects of these cycles on Earth phenomena. They represent and explain the effects of forces acting on objects. They use particle theory to explain the physical properties of substances and develop processes that separate mixtures. Students identify the factors that can influence development of and lead to changes in scientific knowledge. They explain how scientific responses are developed and can impact society. They explain the role of science communication in shaping viewpoints, policies and regulations. Students plan and conduct safe, reproducible investigations to test relationships and aspects of scientific models. They identify potential ethical issues and intercultural considerations required for field locations or use of secondary data. They use equipment to generate and record data with precision. They select and construct appropriate representations to organise data and information. They process data and information and analyse it to describe patterns, trends and relationships. They identify possible sources of error in methods and identify unanswered questions in conclusions and claims. They identify evidence to support their conclusions and construct arguments to support or dispute claims. They select and use language and text features appropriately for their purpose and audience when communicating their ideas and findings.
