Science Science and Technology, Understanding Technology: 1. Identify that science and technology are essential social enterprises but alone they can only indicate what can happen, not what should happen. Realize the latter involves human decisions about the use of knowledge. Science and Technology, Understanding Technology: 3. Explore and explain any given technology that may have a different value for different groups of people and at different points in time (e.g., new varieties of farm plants and animals have been engineered by manipulating their genetic instructions to reproduce new characteristics). Scientific Inquiry, Doing Scientific Inquiry: 2. Evaluate assumptions that have been used in reaching scientific conclusions. Scientific Ways of Knowing, Scientific Theories: Explain how theories are judged by how well they fit with other theories, the range of included observations, how well they explain observations and how effective they are in predicting new findings.
