27.3: Electromagnetic Waves
10 March
BOOK NOTES
10-15 min 1. Review Chapter 27 sections 3 and complete Cornell Notes notes for this section including the "terms to know". Include diagrams and examples when possible. VIDEO NOTES 10-15 min 2. Add to your Cornell Notes using Electromagnetic Waves: Definition, Sources & Properties, from Education Portal (expires 2 April). Add details and diagrams to your notes. ELECTROMAGNETIC SPECTRUM ONLINE MODULE PRACTICE WS 15-30 min 3. Using the online learning module and tools from the National Science Foundation, explore the *Electromagnetic Spectrum learning module. This module should take some time to explore and complete the practice. Complete the practice sheet and check in when completed. Exploration 3 is extra credit. ![]()
MASTERY CHECK
5-10 min 4. Electromagnetic waves originate from the vibrations of pure energy and can travel in a vacuum or thru matter. Mechanical Waves originate from the vibrations matter and can only travel thru matter. Explain why radio waves can travel through space, but sound waves cannot. |
Standard(s) Practiced:
P4.6A P4.6B Big Idea: The electromagnetic spectrum consists of radio waves, microwaves, infrared, light, ultraviolet rays, X-rays, and gamma rays and originate from the vibrations of pure energy. Terms to Know Electromagnetic wave Electromagnetic Spectrum Infrared Ultraviolet |
27.4: Light and Transparent Materials
27.5: Opaque Materials
11-12 March
BOOK NOTES
10-15 min 1. Review Chapter 27 sections 4 and 5 and complete Cornell Notes notes for this section including the "terms to know". Include diagrams and examples when possible. VIDEO NOTES 10-15 min 2. Add to your Cornell Notes using Transparent and Opaque Materials in Electromagnetic Waves, from Education Portal (expires 2 April). Add details and diagrams to your notes. PRACTICE 5-10 min Review the Opaque, Translucent and Transparent Introduction video. Create your own example of each in your lab notebook, screencast or voice thread. REVIEW GAME
5-10 min Play the Transparent, Opaque, and Translucent Game. The game is basic but a good review of the big ideas for this section. MASTERY CHECK 5-10 min How do the transparency and opacity of objects depends on how light waves interact with the materials of those objects. Provide an example for one transparent object and one opaque object. |
Standard(s) Practiced:
P4.9A P4.9B Big Idea: -Light passes through materials whose atoms absorb the energy and immediately reemit it as light. -In opaque materials, any coordinated vibrations given by light to the atoms and molecules are turned into random kinetic energy. Terms to Know: Transparent Opaque Reflection Absorption Remission |
27.Time Delays and Sound Waves
|
Standard(s) Practiced:
P4.6C P4.6D Big Idea: Radio waves travel at the speed of light, 300,000 km/sec. Terms to Know: Radio Wave |
