Biv lives here provides activities in class, in laboratory, and on the web for students to learn basics of electromagnetic waves.  There is an emphasis on visible and ultraviolet light.      Physical Science Topic: Electromagnetic waves Grade Level: Ninth Student Lesson: Electromagnetic Waves URL:  http://ctap295.ctaponline.org/~davidson/student/                                                                           Back to the top. Standards Addressed Ninth  Grade Science: Physics 4. Waves have characteristic properties that do not depend on the type of wave. As a basis for understanding this concept: e. Students know radio waves, light, and X-rays are different wavelength bands in the spectrum of electromagnetic waves whose speed in a vacuum is approximately 3 X 10 8 m/s (186,000 miles/second). f. Students know how to identify the characteristic properties of waves: interference (beats), diffraction, refraction, Doppler effect, and polarization.   Back to the top Instructional Objectives 1. Given a chart of the electromagnetic spectrum, students will be able to identify the wavelength bands of radio waves, light, microwaves and X-rays. 2. Students will be able to state the speed of electromagnetic waves. 3. Students will be able to explain that electromagnetic waves travel in a vacuum. 4. In reference to light, students will be able to identify the correct definition of at least four of the following characteristics properties of waves: interference, diffraction, refraction, Doppler effect, polarization. 5. Students will be able to identify in a list at least one method of observing any characteristic property of light waves. 6. Given a property of a light wave, students will be able to identify in  a list at least one use of that property. 7. In reference to light, students will be able to compare and contrast the terms: color, reflection, transmission, and absorption. Back to the top Student Activities Introductory Activity Students will explore characteristics of light at Amazing Space Web-based Activities in the activity Star Light, Star Bright at http://amazing-space.stsci.edu/ . Enabling Activities Reading in text on light, demonstrations and labs on characteristics of light.  PowerPoint about Star Light:  http://pls.atu.edu/physci/physics/people/psjr/courses/PHYS4213/Stellar/sld001.htm   A short term Web Quest  to develop information on properties of light and of electromagnetic waves in general.  This is a data acquisition and integration activity, students will be asked to generate questions and to search for answers.  Mini Web Quest  Students will participate in collaborative research at KanCRN.   http://KANcrn.org/uvb/ by making a daily UV-B high reading at solar noon using the Sunsor UV meter and collect daily weather data at the same time.  Link to Activity 5: Safe in the Sun, an introduction to the use of the Sunsor UV-a and UV-b meter. http://www.wv-hsta.org/TeacherInfo/NIH_Modules/uv/matter_activity5.htm    Culminating Activity      Web Page: Students will create a web page to report the results of their information collection and analysis.  This is Searching for Roy G.

Biv  Collaborative Research Materials:  Sunsor UV meter, Source: Sunsor, Inc.  (This meter may be purchased from Sunsor for $39.95 plus shipping and handling charges of $4.50 from Sunsor, Inc. 4361 Route 8 Allison Park, PA 15101,  1/800/492-9815), a source of daily weather information,  data collection sheet (available at the KanCRN site  http://KANcrn.org/uvb/. List and link the web resources for your learning activity(ies) here. Also link supplementary materials such as PDF files and /or document files. Culminating Activity Students will need to know how to use a web page editor such as Netscape Composer or Front Page.  Students can create their pages in Microsoft Word and save them as a web page.   Students will need access to a computer and to the internet.   Back to the top   El Dorado High School El Dorado County Anne Davidson anndavid@innercite.com Last Revised:04/25/01
