He currently coordinates work between the sectors of education in WA supporting Australian Curriculum implementation. Emma also designed and managed a small not-for-profit school for at-risk youth in Victoria for two years prior to moving to Vietnam.

Organisms are organised on a cellular basis and have a finite life span. All organisms comprise one or more cells. Multi-cellular organisms have cells that are differentiated according to their function. All the basic functions of life are the result of what happens inside the cells that make up an organism. Growth is the result of multiple cell divisions. Organisms require a supply of energy and materials for which they often depend on, or compete with, other organisms.
Food provides materials and energy for organisms to carry out the basic functions of life and to grow. Green plants and some bacteria are able to use energy from the sun to generate complex food molecules. Animals obtain energy by breaking down complex food molecules and ultimately depend on green plants as their source of energy source.
In any ecosystem there is competition among species for the energy resources and materials they need to live and reproduce. Genetic information is passed down from one generation of organisms to another. Genetic information in a cell is held in the chemical DNA. Genes determine the development and structure of organisms. In asexual reproduction all the genes in the offspring come from one parent.
In sexual reproduction half of the genes come from each parent. The diversity of organisms, living and extinct, is the result of evolution. All life is directly descended from a universal common ancestor that was a simple one-celled organism.
Over countless generations changes resulting from natural diversity within a species led to the selection of individuals best suited to survive under certain conditions. Species not able to respond sufficiently to changes in their environment become extinct. Science is about finding the cause or causes of phenomena in the natural world. Science is a search to explain and understand phenomena in the natural world.
There is no single scientific method for doing this; the diversity of natural phenomena requires a diversity of methods and instruments to generate and test scientific explanations. Often an explanation derives from the factors that must be present for an event to take place, as shown by evidence from observations and experiments. In other cases, supporting evidence is based on correlations revealed by patterns in systematic observation. Scientific explanations, theories and models are those that best fit the evidence available at a particular time.
A scientific theory or model representing relationships between variables of a natural phenomenon must fit the observations available at the time, and lead to predictions that can be tested. Any theory or model is provisional and subject to revision in the light of new data, even though it may have led to predictions that accord with data in the past.
The knowledge produced by science is used in engineering and technologies to create products to serve human ends. The use of scientific ideas in engineering and technologies has made considerable changes in many aspects of human activity. Advances in technologies enable further scientific activity; in turn this increases understanding of the natural world. In some areas of human activity, technology is ahead of scientific ideas. In other areas, scientific ideas precede technology.
Applications of science often have ethical, social, economic and political implications. The use of scientific knowledge in technologies makes many innovation possible. Whether or not particular applications of science are desirable is a matter that cannot be addressed using scientific knowledge alone. Ethical and moral judgments may be needed, based on such considerations as justice or equity, human safety, and impacts on people and the environment.
