FOUNDATIONS (Grades 1-3)

Students know and are able to do all of the above and the following:

  • 2SC-F1. Recognize that scientific contributions have been made by all kinds of people everywhere in the world

PO 1. Describe how people and cultures, past and present, have made important contributions to scientific knowledge

  • 2SC-F2. Understand that scientific inquiry has produced much knowledge about the world, that much is still unknown, and that some things will always be unknown

PO 1. Describe the results of scientific inquiry in the world (e.g., a timeline of inventions, progression from simple to mechanized tools, understanding weather patterns)

PO 2. Explain how inquiry develops into further exploration of the unknown

  • 2SC-F3. Understand that science involves asking and answering questions and comparing the results to what is already known

PO 1. Explain how asking and answering questions are part of the process of a scientific investigation

PO 2. Compare prior knowledge to the results of a scientific investigation

ESSENTIALS (Grades 4-8)

  • 2SC-E1. Identify major milestones in science that have revolutionized the thinking of the time

(Grades 4-5)

PO 1. Describe major scientific contributions

(Grades 6-8)

PO 1. Describe the effects of major scientific events on society

PO 2. Describe a recent scientific event that has impacted the quality of life

  • 2SC-E2. Describe how science and technology are interrelated

(Grades 4-5)

PO 3. Determine scientific processes involved in a technological advancement

  • 2SC-E3. Provide different explanations for a phenomenon; defend and refute the explanations

(Grades 4-5)

PO 1. Propose several possible explanations for a scientific phenomenon

PO 2. Provide evidence to defend an explanation for a scientific phenomenon

PO 3. Provide evidence to refute an explanation for a scientific phenomenon

(Grades 6-8)

PO 1. Analyze different theories to explain a phenomenon

PO 2. Defend or refute the explanation of a phenomenon

  • 2SC-E4. Identify characteristics of scientific ways of thinking

PO 2. Explain the role of experimentation in scientific inquiry

PO 3. Describe how a scientific theory can be developed and modified

(Grades 6-8)

PO 1. Describe the relationship between theory and hypotheses

PO 2. Describe how experimental procedures can be formulated to test a hypothesis

PO 3. Explain how experimental results may affect a hypothesis and a theory

  • 2SC-E6. Demonstrate how Science is an ongoing process of gathering and evaluating information, assessing evidence for and against theories and hypotheses, looking for patters, and then devising and testing possible explanations.

PROFICIENCY (Grades 9-12)
