• [What is science?: Grades 6-8] Scientific knowledge is open to question and revision as new ideas surface and new evidence is discovered. (P6, NOS3)
• [What is science?: Grades 9-12] Scientific knowledge is open to question and revision as new ideas surface and new evidence is discovered. (P4, P6, NOS3)
• [What is science?: Grades 13-16] Scientific knowledge is open to question and revision as new ideas surface and new evidence is discovered.
• [How science works: Grades 6-8] The process of science involves observation, exploration, testing, communication, and application.
• [How science works: Grades 6-8] Scientists test their ideas by predicting what they would expect to observe if their idea were true and then seeing if that prediction is correct. (P4, P6)
• [How science works: Grades 6-8] Scientists look for patterns in their observations and data. (P4, P5)
• [How science works: Grades 9-12] The process of science involves observation, exploration, testing, communication, and application.
• [How science works: Grades 9-12] 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)
• [How science works: Grades 9-12] Scientists look for patterns in their observations and data. (P4, P5, NOS2)

• [How science works: Grades 13-16] Scientists look for patterns in their observations and data.
• [Hypotheses and theories: Grades 6-8] Hypotheses are potential explanations for what we observe in the natural world. (P6)
• [Hypotheses and theories: Grades 6-8] Hypotheses are usually inspired and informed by previous research and/or observations. They are not guesses. (P6)
• [Hypotheses and theories: Grades 9-12] Hypotheses are proposed explanations for a narrow set of phenomena. (P6)
• [Hypotheses and theories: Grades 9-12] Hypotheses are usually inspired and informed by previous research and/or observations. They are not guesses. (P6)

• [The social side of science: Grades 9-12] Scientists usually work collaboratively. (NOS7)
• [The social side of science: Grades 13-16] Scientists usually work collaboratively.
• [A scientific approach to life: Grades 9-12] Problem-solving and decision-making benefit from a scientific approach.
• [A scientific approach to life: Grades 6-8] Problem-solving and decision-making benefit from a scientific approach.
• [A scientific approach to life: Grades 13-16] Problem-solving and decision-making benefit from a scientific approach.

• NOS Matrix understanding category 3. Scientific knowledge is open to revision in light of new evidence.
• Science and Engineering Practice 4. Analyzing and interpreting data

At the end of this activity, students are asked to reflect on whether they were doing science. The activity can serve as an effective introduction to or reminder about the process of science, as well as provide an opportunity for students to reflect on the basic characteristics that help delimit the scientific enterprise.
