High School:
Constructing New Scientific Knowledge (C) I.1
All students will ask questions that help them learn about the world
1. Ask questions that can be investigated empirically.
Key concepts: Questions often build on existing knowledge.
Real-world contexts: Any in the sections on Using Scientific Knowledge.
All students will design and conduct investigations using appropriate methodology and technology:
2. Design and conduct scientific investigations.
Key concepts: Types of scientific knowledge-hypothesis, theory, observation, conclusion, law, data, generalization. Aspects of field research-hypothesis, design, observations, samples, analysis, conclusion. Aspects of experimental research-hypothesis, design, variable, experimental group, control group, prediction, analysis, conclusion. Investigations are based on questions about the world (see C-I.1 h.1).
Real-world contexts: Any suggested in Using Scientific Knowledge benchmarks for which students would design and/or conduct investigations.
3. Recognize and explain the limitations of measuring devices.
Key concepts: Uncertainty, error, range, tolerances, accuracy, precision.
Tools: Balance, thermometer, measuring tape, ruler, graduated cylinder, electronic measuring devices.
Real-world contexts: Experiments that use quantitative data; manufacturing systems where measurements are critical.
All students will learn from books and other sources of information:
4. Gather and synthesize information from books and other sources of information.
Key concepts: Scientific journals, text- and computerbased reference materials.
Real-world contexts: Libraries, technical reference books, Internet, computer software.
All students will communicate findings of investigations, using appropriate technology.
5. Discuss topics in groups by making clear presentations, restating or summarizing what others have said, asking for clarification or elaboration, taking alternative perspectives, and defending a position.
Key concepts: Logical argument, summary, clarification, elaboration, alternative perspectives.
Real-world contexts: Newspaper or magazine articles discussing a topic of social concern.
Reflecting on Scientific Knowledge (R) II.1
All students will analyze claims for their scientific merit and explain how scientists decide what constitutes scientific knowledge:
1. Justify plans or explanations on a theoretical or empirical basis.
Key concepts: Aspects of logical argument, including evidence, fact, opinion, assumptions, claims, conclusions, observations.
Real-world contexts: Any in the sections on Using Scientific Knowledge.
2. Describe some general limitations of scientific knowledge.
Key concepts: Understanding of the general limits of science and scientific knowledge as constantly developing human enterprises; recognizing that arguments can have emotive, economic, and political dimensions as well as scientific.
Real-world contexts: Any in the sections on Using Scientific Knowledge.
3. Show how common themes of science, mathematics, and technology apply in real-world contexts.
Thematic ideas: Systems-subsystems, feedback models, mathematical constancy, scale, conservation, structure, function, adaptation.
Real-world contexts: Any in the sections on Using Scientific Knowledge.
4. Discuss the historical development of key scientific concepts and principles.
Key concepts: Historical, political, social, and economic factors influencing the development of science. See Benchmarks for Science Literacy, AAAS, Chapter 10.
Real-world contexts: Historical development of key scientific theories.
All students will show how science and technology affect our society:
5. Explain the social and economic advantages and risks of new technology.
Key concepts: Cost-benefit analysis; See LO h.5 (health technology), PME-IV.1 h.1 (household and agricultural materials, EG-V.1 h.4 (resource use), LEC-III.5 h.6 (effects of urban development and agriculture on ecosystems), EAW-V.3 h.4 (air pollution), EH-V.2 h.2 (water pollution.)
Real-world contexts: Issues related to new technologies, including ones in health-care, transportation, communications, manufacturing, information and media.
6. Develop an awareness of and sensitivity to the natural world.
Key concepts: Appreciation of the balance of nature and the effects organisms have on each other, including the effects humans have on the natural world.
Real-world contexts: Any in the sections on Using Scientific Knowledge appropriate to high school.
All students will show how people of diverse cultures have contributed to and influenced developments in science:
7. Describe the historical, political, and social factors affecting developments in science.
Key concepts: Historical, political, social, and economic factors influencing the development of science.
Real-world contexts: The development of the suncentered model of the solar system and political pressures on Galileo; the development of Darwin’s theory of evolution by natural selection.
Motion of Objects (PMO) IV.3
All students will describe how things around us move, explain why things move as they do, and demonstrate and explain how we control the motions of objects:
1. Analyze patterns of force and motion in the operation of complex machines.
Key concepts: Electrical and/or mechanical components of complex machines.
Real-world contexts: Machines, such as bicycles, automobiles, pumps, electrical motors.
Solar System, Galaxy and Universe (ES) V.4
All students will explain how we learn about the universe.
4. Explain how technology and scientific inquiry have helped us learn about the universe.
Key concepts: Information-radiant energy, radio waves, light, spectra, color of stars, moon and meteor samples. Devices-radio, optical and other types of telescopes, space probes, satellites, computer imaging/modeling (see PWV-IV.4 h.4.) Problems for investigation—geology and weather of planets and moons, origins, extraterrestrial life.
Real-world contexts: Histories of discoveries, stories of exploration, visits to observatories and planetariums; videos showing space exploration; samples of space materials, including moon rocks and meteorites; remote sensing data; SETI-Search for Extraterrestrial Life.
