Academic Words List
The purpose of this document is to give the school community access to a list of the key academic words used across all the subject areas at CBHS.
The words are arranged alphabetically and by year level. Each word is followed by a subject-specific definition and, in some cases, an example (in italics) of how that word might be used in that subject area or a further clarification. Many of these words build on each other over various levels or are used at successive levels, with development in their meaning and expectations.
Below is a brief list of key verbs used in the five SOLO Taxonomy levels. Many of these words, or words like them, appear in our school list.

Change | Change involves any alteration to the natural or cultural environment. Change can be spatial and/or temporal. Change is a normal process in both natural and cultural environments. It occurs at varying rates, at different times, and in different places. Some changes are predictable, recurrent, or cyclic, while others are unpredictable or erratic. Change can bring about further change. |
Cultural | The human environment. |
Describe | This means to identify and give an account of; to make reference to the qualities, characteristics or recognisable features. A simple explanation can also be included. |
Environments | Environments can be natural and/or cultural. They have particular characteristics and features that can be the result of natural and/or cultural processes. The particular characteristics of an environment may be similar to and/or different from another. |
Explain | This means to provide reasons for, to account for, to provide a clear answer, to clarify. Logical reasons are provided. |
Interaction | Interaction involves elements of an environment affecting each other and being linked together. Interaction incorporates movement, flows, connections, links, and interrelationships. Landscapes are the visible outcome of interactions. Interaction can bring about environmental change. |
Natural | The physical environment. |
Patterns | Patterns can be spatial, such as the arrangement of features on the earth’s surface, or temporal, such as how characteristics differ over time in recognisable ways. |
Perspectives | The way people view and interpret environments. Perspectives and values may be influenced by culture, environment, social systems, technology, economic and political ideology. They may influence how people interact with environments and the decisions and responses that they make. |
Processes | A sequence of actions, natural and/or cultural, that shape and change environments, places and societies. Some examples of geographic processes include erosion, migration, desertification, and globalisation. |
Sustainability | Sustainability involves adopting ways of thinking and behaving that allow individuals, groups, and societies to meet their needs and aspirations without preventing future generations from meeting theirs. Sustainable interaction with the environment may be achieved by preventing, limiting, minimizing, or correcting environmental damage to water, air, and soil, as well as considering ecosystems and problems related to waste, noise, and visual pollution. |
Aroha | love and empathy. It is an attitude and an important cultural value of Māori, derived from a particular Māori view of the natural world and the place of Māori within it. Aroha is an important concept that underpins a Māori environmental management system. |
Kaitiakitanga | to “care for” the environment. It is the sustainable use, management and control of natural and physical resources that are carried out to the mutual benefit of people and resources. |
Taonga | is a resource either physical or cultural that can be found in the environment (including features within the environment e.g. lakes, mountains, rivers, also including people, te reo, whakapapa, etc.). |
Tino Rangatiratanga | - includes the rights, responsibilities and obligations involving the use, management and control of the land and other resources. |
Whanaungatanga | Māori share a common whakapapa with other people/taonga and therefore a strong sense of responsibility and reciprocal obligations toward those people/taonga. This forms an important part of a holistic world-view. All taonga are interrelated, interconnected and Interdependent. The life force (mauri) of taonga must be protected. The sustainable management of taonga is therefore paramount to our survival. |
