Chemistry

Chemicals_in_flasks.jpg
Chemistry is the science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions.


Chemistry (from Arabic: كيمياء Latinized: chem (kēme), meaning "value")[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics, but while physics takes a more general and fundamental approach, chemistry is more specialized, being concerned with the composition, behavior, structure, and properties of matter, as well as the changes it undergoes during chemical reactions.[2] It is a physical science for studies of various atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, which incorporates the concepts of energy and entropy in relation to the spontaneity ofchemical processes.
Disciplines within chemistry are traditionally grouped by the type of matter being studied or the kind of study. These include inorganic chemistry, the study of inorganic matter; organic chemistry, the study of organic matter;biochemistry, the study of substances found in biological organisms; physical chemistry, the energy related studies of chemical systems at macro, molecular and submolecular scales; analytical chemistry, the analysis of material samples to gain an understanding of their chemical composition and structure. Many more specialized disciplines have emerged in recent years, e.g. neurochemistry the chemical study of the nervous system (seesubdisciplines).



Biology

Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.[1]
Biology is a vast subject containing many subdivisions, topics, and disciplines.
Among the most important topics are five unifying principles that can be said to be the fundamental axioms of modern biology:[2]
  1. Cells are the basic unit of life
  2. New species and inherited traits are the product of evolution
  3. Genes are the basic unit of heredity
  4. An organism will regulate its internal environment to maintain a stable and constant condition
  5. Living organisms consume and transform energy.
Subdisciplines of biology are recognized on the basis of the scale at which organisms are studied and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues, organs, and organ systems of an organism; and ecology examines how various organisms interrelate with their environment.[3]



Environmental Science


RATIONALE
Environmental Science provides the opportunity for students to understand the structure, function and diversity of natural ecosystems on this planet and evaluate the impacts of human activities on them. Students examine strategies to maintain and protect the ecological health of the environment while meeting the needs and desires of human populations.
Environmental Science investigates the interactions between natural and human systems. This study examines the application of environmental science to ecologically sustainable development and environmental management. Students should understand the values and attitudes that underpin environmental decisions and reflect on effective ways for modifying behaviour of individuals and groups for positive environmental outcomes.
While undertaking this study, students will develop skills in practical scientific investigations, environmental fieldwork techniques, report writing, research and analysis.

AIMs
This study is designed to enable students to:

• understand the structure, function and diversity of ecosystems; state of ecological health;
• examine human impacts on ecosystems and investigate ways to minimise them;
• understand the concepts and principles of environmental science;
• investigate the role of science in the management of the environment;
• develop a critical perspective on environmental science;
• undertake activities that contribute positively to the sustainability of the environment.
