Appendix A
California schools use the Next Generation Science Standards to inform and guide their instruction. This unit for Physiology crosses both into Physical and Life Science standards. Four of the NGSS standards are annotated here though there are more standards that this unit addresses.
Science and Engineering Practices: Obtaining, Evaluating, and Communicating Information
HS-PS4-4 Evaluate the validity and reliability of claims in published materials of the effects that different frequencies of electromagnetic radiation have when absorbed by matter. 32
Disciplinary Core Ideas: Wave Properties
HS-PS4A- 1 The wavelength and frequency of a wave are related to one another by the speed of travel of the wave which depends on the type of wave and the medium through which it passes. 32
Students will fulfill this standard by reviewing different sources (web-based, articles, journals, and videos) to decide how the EM waves affect their daily lives. They will look at photons at different frequencies, describe the energy associated with radiation types, and assess whether the harm to human tissue.
Disciplinary Core Ideas: Wave Properties
HS- PS4B- 4 Shorter wavelength electromagnetic radiation (ultraviolet, X-rays, gamma rays) can ionize atoms and cause damage to living cells. 32
Through classroom hands-on activities students will understand the difference between UV, X-ray, and gamma rays and will be able to articulate after each activity how they may damage cells.
Crosscutting Concepts to Engineering and Technology
HS-PS4-5 Information Technologies and Instrumentation Multiple technologies based on the understanding of waves and their interactions with matter are part of everyday experiences in the modern world (e.g., medical imaging, communications, scanners) and in scientific research. They are essential tools for producing, transmitting, and capturing signals and for storing and interpreting the information contained in them.32
Student research and mock-EPA hearing activity will show students’ knowledge regarding new and emerging medical technologies. Students should be able to address the necessity of some level of radiation exposure for the sake of medical progress.
