Performance Standard Level 3, Ages 11–14

Students describe the steps in the development of a widely used technology (e.g., Teflon©, sticky notes, nylon, penicillin, etc.)

Sample Assessment Ideas

Sample Assessment Ideas

  • Students research a serendipitous discovery (e.g., Teflon©, sticky notes, nylon, penicillin, Jello, etc.); write a report or create a diagram describing the discovery.

  • Students discuss “new ideas” that eventually overcame skepticism (e.g., plate tectonics, existence of viruses, atoms and molecules).

Recognize and analyze alternative explanations and predictions. Students should develop the ability to listen to and respect the explanations proposed by other students. They should remain open to and acknowledge different ideas and explanations, be able to accept the skepticism of others, and consider alternative explanations. (Page 148)

Science advances through legitimate skepticism. Asking questions and querying other scientists’ explanations is part of scientific inquiry. Scientists evaluate the explanations proposed by other scientists by examining evidence, comparing evidence, identifying faulty reasoning, pointing out statements that go beyond evidence, and suggesting alternative explanations for the same observations. (Page 148)

 

Benchmarks

Scientific knowledge is subject to modification as new information challenges prevailing theories and as a new theory leads to looking at old observations in a new way. (Page 7)
