How do waves behave differently from particles?  \nSummary  \nIn this fifth and final lesson of the \"What Is a Wave?\" unit, students will observe two demonstrations of waves interacting with different types of matter and form conclusions to understand how light travels through matter. Students will complete a Concept Card Map activity to demonstrate their understanding of the unit's content and concepts.  \nSnapshot  \nEngage  \nStudents generate key concepts based on the previous lessons.  \nExplore  \nStudents make observations and develop claims about light traveling through matter.  \nExplain  \nStudents observe a laser demonstration and form conclusions about light frequency.  \nExtend  \nStudents brainstorm other forms of radiation.  \nEvaluate  \nStudents create a Concept Card Map to summarize their understanding of the unit.  \n[https://learn.k20center.ou.edu/lesson/1697?rev=24658](https://learn.k20center.ou.edu/lesson/1697?rev=24658)  \nPage 2 of 11  \nStandards  \nOklahoma Academic Standards (Physical Science)  \nPS. PS4.1 : Use mathematical representations to explain both qualitative and quantitative relationships among frequency, wavelength, and speed of waves traveling in various media.  \nPS. 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.  \nPS. PS4.4. 1: When light or longer wavelength electromagnetic radiation is absorbed in matter, it is  \ngenerally converted into thermal energy (heat) .  \nPS. PS4.4. 2: Shorter wavelength electromagnetic radiation (ultraviolet, X-rays, gamma rays) can ionize atoms and cause damage to living cells.  \nPS. PS4.4. 3: Photoelectric materials emit electrons when they absorb light of high enough frequency.  \nAttachments  \n  CERTIfy Your Thinking Activity—New Direction-Spanish.docx  \n  CERTIfy Your Thinking Activity—New Direction-Spanish. pdf  \n  CERTIfy Your Thinking Activity—New Direction.docx  \n  CERTIfy Your Thinking Activity—New Direction. pdf  \n Concept Card Packet Waves—New Direction-Spanish.docx  \n Concept Card Packet Waves—New Direction-Spanish. pdf  \n Concept Card Packet Waves—New Direction.docx  \n Concept Card Packet Waves—New Direction. pdf  \n  Lesson Slides—New Direction. pptx  \n  Wave Vocabulary Packet—New Direction-Spanish.docx  \n  Wave Vocabulary Packet—New Direction-Spanish. pdf  \n  Wave Vocabulary Packet—New Direction.docx  \n  Wave Vocabulary Packet—New Direction. pdf  \n  Wave Vocabulary Teacher Guide—New Direction.docx  \n  Wave Vocabulary Teacher Guide—New Direction. pdf  \nMaterials  \n Lesson Slides (attached)  \n Concept Card Packet (attached; one per group of 3-4 students)  \n C.
