Overview: Students are asked to determine what the interior construction of the mystery tube looks like. Working in groups, students pose explanations for what they are observing and test their ideas. Author/Source: UCMP Grade: 9-12 Discipline: Nature and Process of Science Time: One period Concepts: Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details. Scientists strive to test their ideas with evidence from the natural world; a hallmark of science is exposing ideas to testing. (P3, P4, P6, P7, NOS2) Scientific knowledge is open to question and revision as new ideas surface and new evidence is discovered. (P4, P6, NOS3) Scientific ideas cannot be absolutely proven. The process of science involves observation, exploration, testing, communication, and application. Scientists test their ideas (hypotheses and theories) by figuring out what expectations are generated by an idea and making observations to find out whether those expectations are borne out. (P4, P6) Hypotheses are proposed explanations for a narrow set of phenomena. (P6) Hypotheses are usually inspired and informed by previous research and/or observations. They are not guesses. (P6) Scientists usually work collaboratively. (NOS7) Teacher background: Process of science Exploration and discovery Scientific arguments/evidence/testing ideas Hypotheses/theories
