Tennessee Secondary School Science Framework for Physical Science and Chemistry
PROCESS OF SCIENCE - GOAL: To enable students to demonstrate the processes of science by posing questions and investigating phenomena through language, methods and instruments of science.
1.1 OBSERVING - The senses are used to develop an awareness of an event or object and the properties thereof.

1.5c - Information should be related to prior knowledge.
1.6 COMMUNICATING - An essential aspect of science is the act of accurately and effectively conveying oral, written, graphic or electronic information from the preparer to the user.
1.6a - The sharing and disseminating of results should be done in a clear and concise manner.
UNIFYING CONCEPTS OF SCIENCE - GOAL: To enable students to acquire scientific knowledge by applying concepts, theories, principles and laws from life/environmental, physical and earth/space sciences.
2.1 SCALE AND MODEL - The development of models provides a conceptual bridge between the concrete and the abstract, while the use of scales allows for a comparison of differences in magnitude between the model and the desired form.
2.1a - A model is a representation used to simplify complex phenomena.
2.1b - Different models can be used to represent the same thing. The kind of model used and its complexity depends on its purpose.
2.1c - Models are often used to study processes that happen too slowly, too quickly, or on too small or too large a scale to observe directly.
2.1d - The scale chosen for a model determines its effectiveness.
2.1e - Different properties are not affected to the same degree by changes in scale; large changes in scale typically change the way things work.
2.2 FORM AND FUNCTION - Form may determine the function of a material or a system, and function may alter form.
2.2a - How an object functions is related to its form.
2.2b - Form tends to dictate function, thus an alteration of form may lead to a change in function.
2.3 ORGANIZATION - Everything is organized as related systems within systems.
2.3a - Natural phenomena display a wide variety of similarities and differences.
2.3b - Groupings are based on similarities related to structure and function.
2.4 INTERACTIONS - At all levels of living and non-living systems, matter and energy act and react to determine the nature of our environment.
2.4a - Interactions occur on scales ranging from elementary particles to galaxies.
2.4b - Interactions of matter and energy shape our world.
2.5 CHANGE - Interactions within and among systems may result in changes in the properties, position, movement, form, or function of systems.
2.5a - Everything is constantly changing; rates of change vary over a wide scale with a great variety in patterns of change.
2.5b - Cycles of change can be extended in scales of time, space, and material.
2.6 CONSERVATION - In any natural process the form may change but nothing is lost.
2.6a - Although there can be transformations of matter and energy in changes, the sum of matter and energy is conserved.
HABITS OF MIND - GOAL: To enable students to demonstrate ways of thinking and acting inherent in the practice of science; and to exhibit an awareness of the historical and cultural contributions to the enterprise of science.
3.1 HISTORICAL AND CULTURAL PERSPECTIVE - The knowledge and processes of science have evolved over time as an approximation of truth within cultural contexts.
3.1a - Although some scientific knowledge is very old, it is still applicable today.
3.1b - Individual initiative and vision create changes in science.
3.1c - The desire to understand the natural environment and to predict the course of natural events is universal.
3.1d - The growth of scientific knowledge and most technological advances have resulted from the work accumulated over many centuries by men and women in every part of the world.
3.1e - There are different traditions in science concerning the subject and method of investigation; however, they all have in common certain basic beliefs about the value of evidence, logic and argument.
3.1f - Progress in science depends heavily on societal events, and the course of history often depends on scientific and technological developments.
3.2 ASSUMPTIONS - The recognition and criticism of the validity of an argument through presentation of data and differentiation between fact and assumption in the preparation of an explanation for a natural phenomenon are vital parts of the scientific process.
3.2a - Science is based upon suppositions derived from observations of natural phenomena.
3.2b - Predictions are based on previous knowledge.
3.2c - The critical assumptions behind any line of reasoning must be made explicit so that the validity of the position taken can be judged.
3.2d - The validity of an investigation cannot be accepted unless the complete investigation can be independently duplicated.
3.3 ESTIMATION AND COMPUTATION - Scientists judge the level of precision needed to approximate a reasonable response and perform calculations with or without the aid of mechanical devices.
3.4 METHODS - A variety of techniques is used by scientists to classify and solve problems.
