ACSBL021

In addition to biotic factors, abiotic factors including climate and substrate can be used to describe and classify environments

ACSBL021 | Content Descriptions | Unit 1 | Biology | Science | Senior secondary curriculum

ACSBL027

Ecosystems can change dramatically over time; the fossil record and sedimentary rock characteristics provide evidence of past ecosystems and changes in biotic and abiotic components

ACSBL027 | Content Descriptions | Unit 1 | Biology | Science | Senior secondary curriculum

ACSBL028

Human activities (for example, over-exploitation, habitat destruction, monocultures, pollution) can reduce biodiversity and can impact on the magnitude, duration and speed of ecosystem change

ACSBL028 | Content Descriptions | Unit 1 | Biology | Science | Senior secondary curriculum

ACSBL029

Models of ecosystem interactions (for example, food webs, successional models) can be used to predict the impact of change and are based on interpretation of and extrapolation from sample data (for example, data derived from ecosystem surveying techniques); …

ACSBL029 | Content Descriptions | Unit 1 | Biology | Science | Senior secondary curriculum

ACSBL091

In additional to environmental selection pressures, mutation, gene flow and genetic drift can contribute to changes in allele frequency in a population gene pool and results in micro-evolutionary change

ACSBL091 | Content Descriptions | Unit 3 | Biology | Science | Senior secondary curriculum

ACSBL110

Homeostasis involves a stimulus-response model in which change in external or internal environmental conditions is detected and appropriate responses occur via negative feedback; in vertebrates, receptors and effectors are linked via a control centre …

ACSBL110 | Content Descriptions | Unit 4 | Biology | Science | Senior secondary curriculum

ACSCH003

Conduct investigations, including the use of devices to accurately measure temperature change and mass, safely, competently and methodically for the collection of valid and reliable data

ACSCH003 | Content Descriptions | Unit 1 | Chemistry | Science | Senior secondary curriculum

ACSCH073

Catalysts, including enzymes and metal nanoparticles, affect the rate of certain reactions by providing an alternative reaction pathway with a reduced activation energy, hence increasing the proportion of collisions that lead to a chemical change

ACSCH073 | Content Descriptions | Unit 2 | Chemistry | Science | Senior secondary curriculum

ACSCH102

Volumetric analysis methods involving acid-base reactions rely on the identification of an equivalence point by measuring the associated change in pH, using chemical indicators or pH meters, to reveal an observable end point

ACSCH102 | Content Descriptions | Unit 3 | Chemistry | Science | Senior secondary curriculum

ACSES077

Ecosystems provide a range of renewable resources, including provisioning services (for example, food, water, pharmaceuticals), regulating services (for example, carbon sequestration, climate control), supporting services (for example, soil formation, …

ACSES077 | Content Descriptions | Unit 3 | Earth and Environmental Science | Science | Senior secondary curriculum

ACSES104

Natural processes (for example, oceanic circulation, orbitally-induced solar radiation fluctuations, the plate tectonic supercycle) and human activities contribute to global climate changes that are evident at a variety of time scales

ACSES104 | Content Descriptions | Unit 4 | Earth and Environmental Science | Science | Senior secondary curriculum

ACSES105

Human activities, particularly land-clearing and fossil fuel consumption, produce gases (including carbon dioxide, methane, nitrous oxide and hydrofluorocarbons) and particulate materials that change the composition of the atmosphere and climatic conditions …

ACSES105 | Content Descriptions | Unit 4 | Earth and Environmental Science | Science | Senior secondary curriculum

ACSES106

Climate change affects the biosphere, atmosphere, geosphere and hydrosphere; climate change has been linked to changes in species distribution, crop productivity, sea level, rainfall patterns, surface temperature and extent of ice sheets

ACSES106 | Content Descriptions | Unit 4 | Earth and Environmental Science | Science | Senior secondary curriculum

ACSES107

Geological, prehistorical and historical records provide evidence (for example, fossils, pollen grains, ice core data, isotopic ratios, indigenous art sites) that climate change has affected different regions and species differently over time

ACSES107 | Content Descriptions | Unit 4 | Earth and Environmental Science | Science | Senior secondary curriculum

ACSES108

Climate change models (for example, general circulation models, models of El Nino and La Nina) describe the behaviour and interactions of the oceans and atmosphere; these models are developed through the analysis of past and current climate data, with …

ACSES108 | Content Descriptions | Unit 4 | Earth and Environmental Science | Science | Senior secondary curriculum

ACSPH020

Provided a substance does not change state, its temperature change is proportional to the amount of energy added to or removed from the substance; the constant of proportionality describes the heat capacity of the substance

ACSPH020 | Content Descriptions | Unit 1 | Physics | Science | Senior secondary curriculum

ACSPH021

Change of state involves internal energy changes to form or break bonds between atoms or molecules; latent heat is the energy required to be added to or removed from a system to change the state of the system

ACSPH021 | Content Descriptions | Unit 1 | Physics | Science | Senior secondary curriculum

ACSPH024

Because energy is conserved, the change in internal energy of a system is equal to the energy added or removed by heating plus the work done on or by the system

ACSPH024 | Content Descriptions | Unit 1 | Physics | Science | Senior secondary curriculum

ACSPH031

Einstein’s mass/energy relationship, which applies to all energy changes, enables the energy released in nuclear reactions to be determined from the mass change in the reaction

ACSPH031 | Content Descriptions | Unit 1 | Physics | Science | Senior secondary curriculum

ACSPH040

The energy available to charges moving in an electrical circuit is measured using electric potential difference, which is defined as the change in potential energy per unit charge between two defined points in the circuit
