Working Effectively: Contributing to the work of a brainstorming group, laboratory partnership, cooperative learning group, or project team; planning procedures; identify and managing responsibilities of team members; and staying on task, whether working alone or as part of a group.
Gathering and Processing Information: Accessing information from printed media, electronic data bases, and community resources and using the information to develop a definition of the problem and to research possible solutions.
Generating and Analyzing Ideas: Developing ideas for proposed solutions, investigating ideas, collecting data, and showing relationships and patterns in the data.
Common Themes: Observing examples of common unifying themes, applying them to the problem, and using them to better understand the dimensions of the problem.
Realizing Ideas: Constructing components or models, arriving at a solution, and evaluating the result.
Presenting Results: Using a variety of media to present the solution and to communicate the results.
Scientific explanations are built by combining evidence that can be observed with what people already know about the world.
Learning about the historical development of scientific concepts or about individuals who have contributed to scientific knowledge provides a better understanding of scientific inquiry and the relationship between science and society.
Science provides knowledge, but values are also essential to making effective and ethical decisions about the application of scientific knowledge.
Inquiry involves asking questions and locating, interpreting, and processing information from a variety of sources.
Inquiry involves making judgments about the reliability of the source and relevance of information.
Scientific explanations are accepted when they are consistent with experimental and observational evidence and when they lead to accurate predictions.
All scientific explanations are tentative and subject to change or improvement. Each new bit of evidence can create more questions than it answers. This leads to increasingly better understanding of how things work in the living world.
Well-accepted theories are ones that are supported by different kinds of scientific investigations often involving the contributions of individuals from different disciplines.
