2 History and Nature of Science
1 Identify individual and cultural contributions to scientific knowledge.
PO 1 Identify how diverse people and/or cultures, past and present, have made important contributions to scientific innovations (e.g., John Muir [naturalist], supports Strand 4; Thomas Edison [inventor], supports Strand 5; Mae Jemison [engineer, physician, astronaut], supports Strand 6,; Edmund Halley [scientist], supports Strand 6).
PO 2 Describe science-related career opportunities.
2 Understand how science is a process for generating knowledge.
PO 1 Describe how, in a system (e.g., terrarium, house) with many components, the components usually influence one another.
PO 2 Explain why a system may not work if a component is defective or missing.
3 Science in Personal and Social Perspectives
