S4b The designed world, such as the reciprocal relationship between science and technology; the development of agricultural techniques; and the reasonableness of technological designs.
S4c Health, such as nutrition and exercise; disease and epidemiology; personal and environmental safety; and resources, environmental stress, and population growth.
S4d Impact of technology, such as constraints and trade-offs; feedback; benefits and risks; and problems and solutions.
S4e Impact of science, such as historical and contemporary contributions; and interactions between science and society.
S5 Scientific Thinking: The student demonstrates skill in scientific inquiry and problem solving by using thoughtful questioning and reasoning strategies, common sense and diverse conceptual understanding, and appropriate ideas and methods to investigate science; that is, the student:
S5a Frames questions to distinguish cause and effect; and identifies or controls variables in experimental and non-experimental research settings.
S5b Uses concepts from Science Standards 1 to 4 to explain a variety of observations and phenomena.
S5c Uses evidence from reliable sources to develop descriptions, explanations, and models; and makes appropriate adjustments and improvements based on additional data or logical arguments.
S5d Proposes, recognizes, analyzes, considers, and critiques alternative explanations; and distinguishes between fact and opinion.
S5e Identifies problems; proposes and implements solution; and evaluates the accuracy, design, and outcomes of investigations.
S5f Works individually and in teams to collect and share information and ideas.
S6 Scientific Tools and Technologies: The student demonstrates competence with the tools and technologies of science by using them to collect data, make observations, analyze results, and accomplish tasks effectively; that is, the student:
S6a Uses technology and tools (such as traditional laboratory equipment, video, and computer aids) to observe and measure objects, organisms, and phenomena, directly, indirectly, and remotely, with appropriate consideration of accuracy and precision.
S6b Records and stores data using a variety of formats, such as databases, audiotapes and videotapes.
S6c Collects and analyzes data using concepts and techniques in Mathematics Standard 4, such as mean, median, and mode; outcome probability and reliability; and appropriate data displays.
S6d Acquires information from multiple sources, such as print, the Internet, computer databases, and experimentation.
S6e Recognizes and limits sources of bias in data, such as observer and sample biases.
S7 Scientific Communication: The student demonstrates effective scientific communication by clearly describing aspects of the natural world using accurate data, graphs, or other appropriate media to convey depth of conceptual understanding in science; that is, the student:
S7a Represents data and results in multiple ways, such as numbers, tables, and graphs; drawings, diagrams, and artwork; technical and creative writing; and selects the most effective way to convey the scientific information.
S7b Argues from evidence, such as data produces through his or her own experimentation or data produced by others.
S7c Critiques published materials, such as popular magazines and academic journals.
S7d Explains a scientific concept or procedure to other students.
S7e Communicates in a form suited to the purpose and the audience, such as by writing instructions that others can follow; critiquing written and oral explanations; and using data to resolve disagreements.
S8 Scientific Investigation: The student demonstrates scientific competence by completing projects drawn from the following kinds of investigation, including at least one full investigation each year and, over the course of high school, investigation that integrate several aspects of Science Standards 1 to 7 and represent all four of the kinds of investigation:
S8a Controlled experiment.
S8d Secondary research.
