This short activity quickly engages the participants in the process of developing testable hypotheses. Students come up with multiple hypotheses to explain a set of observations and figure out how to test these hypotheses.
Life Science, Nature and Process of Science
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- Science aims to build explanations of the natural world. (P3, P6)
- Science deals with the natural world and natural explanations.
- 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)
- The process of science involves observation, exploration, testing, communication, and application.
- 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 often try to generate multiple explanations for what they observe. (P7)
- Hypotheses are potential explanations for what we observe in the natural world. (P6)
- Problem-solving and decision-making benefit from a scientific approach.
