Year 7 Science in the Australian Curriculum

AC9S7U01

investigate the role of classification in ordering and organising the diversity of life on Earth and use and develop classification tools including dichotomous keys

AC9S7U02

use models, including food webs, to represent matter and energy flow in ecosystems and predict the impact of changing abiotic and biotic factors on populations

AC9S7U03

model cyclic changes in the relative positions of the Earth, sun and moon and explain how these cycles cause eclipses and influence predictable phenomena on Earth, including seasons and tides

AC9S7U04

investigate and represent balanced and unbalanced forces, including gravitational force, acting on objects, and relate changes in an object’s motion to its mass and the magnitude and direction of forces acting on it

AC9S7U05

use particle theory to describe the arrangement of particles in a substance, including the motion of and attraction between particles, and relate this to the properties of the substance

AC9S7U06

use a particle model to describe differences between pure substances and mixtures and apply understanding of properties of substances to separate mixtures

AC9S7H01

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

AC9S7H02

investigate how cultural perspectives and world views influence the development of scientific knowledge

AC9S7H03

examine how proposed scientific responses to contemporary issues may impact on society and explore ethical, environmental, social and economic considerations

AC9S7H04

explore the role of science communication in informing individual viewpoints and community policies and regulations

AC9S7I01

develop investigable questions, reasoned predictions and hypotheses to explore scientific models, identify patterns and test relationships

AC9S7I02

plan and conduct reproducible investigations to answer questions and test hypotheses, including identifying variables and assumptions and, as appropriate, recognising and managing risks, considering ethical issues and recognising key considerations regarding heritage sites and artefacts on Country/Place

AC9S7I03

select and use equipment to generate and record data with precision, using digital tools as appropriate

AC9S7I04

select and construct appropriate representations, including tables, graphs, models and mathematical relationships, to organise and process data and information

AC9S7I05

analyse data and information to describe patterns, trends and relationships and identify anomalies

AC9S7I06

analyse methods, conclusions and claims for assumptions, possible sources of error, conflicting evidence and unanswered questions

AC9S7I07

construct evidence-based arguments to support conclusions or evaluate claims and consider any ethical issues and cultural protocols associated with using or citing secondary data or information

AC9S7I08

write and create texts to communicate ideas, findings and arguments for specific purposes and audiences, including selection of appropriate language and text features, using digital tools as appropriate
