Glossary
adaptation
A physical or behavioural characteristic that is inherited and which results in an individual being more likely to survive and reproduce in its environment.
analyse
To consider in detail for the purpose of finding meaning or relationships, and identifying patterns, similarities and differences.
characteristic
A distinguishing aspect, including features and behaviours, of an object material, living thing or event.
chart
A visual display of information.
classify
To arrange items into named categories in order to sort, group or identify them.
collaborate
To work with others to perform a specific task.
communication
To convey scientific information using a range of modes, conventions, formats and structures.
conclusion
A judgement based on evidence.
contemporary science
New and emerging science research and issues of current relevance and interest.
continuous data
Quantitative data with a potentially infinite number of possible values along a continuum.
controlled variable
A variable that is kept constant, or changed in constant ways, during an investigation.
convention
An agreed method of representing concepts, information and behaviours.
data
The plural of datum; the measurement of an attribute, the volume of gas or the type of rubber. This does not necessarily mean a single measurement; it may be the result of averaging several repeated measurements and these could be quantitative or qualitative.
dependent variable
A variable that changes in response to changes to the independent variable in an investigation.
design
To plan and evaluate the construction of a product or process, including an investigation.
digital technologies
Systems that handle digital data, including hardware and software, for specific purposes.
discrete data
Quantitative data consisting of a number of separate values where intermediate values are not permissible.
environment
All the surroundings, both living and non-living.
evaluate
To examine and judge the merit or significance of something, including processes, events, descriptions, relationships or data.
evidence
In science, evidence is data that is considered reliable and valid, and that can be used to support a particular idea, conclusion or decision. Evidence gives weight or value to data by considering its credibility, acceptance, bias, status, appropriateness and reasonableness.
experiment or experimental investigation
An investigation that involves carrying out a practical activity.
fair test
An investigation where one variable, the independent variable, is changed and all other conditions, controlled variables, are kept the same; what is measured or observed is referred to as the dependent variable.
field study or work
An observational or practical research undertaken in a normal environment of the subject of a study; that is, an investigation can be conducted outside the laboratory.
force
A push or pull between objects, which may cause one or both objects to change speed or direction of their motion; that is, accelerate, or change their shape. all interactions between matter can be explained as an action of one or a combination of forces.
formal measurement
Measurement based on an agreed standard unit; for example, metre, second, gram.
graph
A visual representation of the relationship between quantities plotted with reference to a set of axes.
guided investigation
An investigation partly directed by a teacher.
informal measurement
Measurement that is not based on any agreed standard unit; for example, hand spans, paces, cups.
investigation
A scientific process of answering a question, exploring an idea or solving a problem that requires activities such as planning a course of action, collecting data, interpreting data, reaching a conclusion and communicating these activities.
law
A statement of a relationship based on available evidence.
material
A substance with particular qualities or that is used for specific purposes.
matter
A physical substance; anything that has mass and occupies space.
methodology
Learners will develop and apply the specialised methods of study designed to meet the requirements of a discipline.
Methodologies vary and have to be adapted at every stage of an inquiry; for example, data sampling techniques, data organisation, presentation and tracking sources of error.
model
A representation that describes, simplifies, clarifies or provides an explanation of the workings, structure or relationships within an object, system or idea.
natural materials
Products or physical matter that come from plants, animals, or earth and have undergone very little modification by humans.
observable
Something that can be seen, heard, felt, tasted or smelled either directly by an individual or indirectly by a measuring device; for example, a ruler, camera or thermometer.
processed materials
Products of physical matter that have been modified from natural materials by human intervention, or that do not occur at all in the natural environment but have been designed and manufactured to fulfil a particular purpose.
property
An attribute of an object or material, normally used to describe attributes common to a group.
qualitative data
Information that is not numerical in nature.
quantitative data
Numerical information.
relate
To identify connections or associations between ideas or relationships or between components of systems and structures.
relationship
A connection or association between ideas or between components of systems and structures.
report
A written account of an investigation.
represent
Use words, images, symbols or signs to convey meaning.
scientific literacy
An ability to use scientific knowledge, understanding, and inquiry skills to identify questions, acquire new knowledge, explain science phenomena, solve problems and draw evidence-based conclusions in making sense of the world, and to recognise how understandings of the nature, development, use and influence of science help us make responsible decisions and shape our interpretations of information.
senses
Hearing, sight, smell, touch and taste.
system
A group of interacting objects, materials or processes that form an integrated whole.
technology
A development of products, services, systems and environments, using various types of knowledge, to meet human needs and wants.
theory
An explanation of a set of observations that is based on one or more proven hypotheses, which has been accepted through consensus by a group of scientists.
