Science Knowledge base:

A knowledge base provides information for science literacy. Information organized as concepts, misconceptions, outcomes, and standards to develop a conceptual framework of science literacy for critical thinking. Information organized in five dimensions:

  1. Habits of mind, attitudes, values, & dispositions to attain positive scientific practices
  2. Inquiry practices
  3. Processes & process skills
  4. Content areas: Physical, Life, Earth & space
  5. Perspectives: Engineering & technology, personal & social, history of science, nature of science
Activities to achieve science literacy for ideas in this knowledge base.

Inquiry practices, processes, & skills

Scientific Inquiry - asking questions, carrying out investigations, questioning, experimenting, & explaining. Ethnographic and experimental investigations

Processes & skills in science practices

Cross-cutting skills & unified processes
