Pedagogical research indicates that students learn better if they are actively engaged. This investigation reinforces the logic of a scientific approach, emphasizes the importance of posing and testing multiple hypotheses, and provides a good opportunity for discussing the role of assumptions in science, avoiding bias, and the relevance of science in our everyday lives.
Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details. - Science works only with testable ideas. (P2, P3, NOS2)
- 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)
- 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)
- Scientists test their ideas using multiple lines of evidence.
- Scientists often try to generate multiple explanations for what they observe. (P7)
- Raw data must be analyzed and interpreted before we can tell whether a scientific idea is likely to be accurate or inaccurate. (P4, P5)
- Scientists try to be objective and work to identify and avoid bias.
- Hypotheses are potential explanations for what we observe in the natural world. (P6)
- Anyone can participate in science.
- Scientific knowledge helps us make decisions that affect our lives every day.
- Problem-solving and decision-making benefit from a scientific approach.
