 When you turn on your car radio, how does the radio station get its music into the car?  Can you see the music go into the radio? 

 As you know, there are many kinds of energy in the universe. The energy given off from the sun is radiant energy (electromagnetic radiation).  The shortest and longest wavelengths are invisible to our eyes, but the medium wavelengths are visible (visible light)

 m7c4-EO7ECE m7c4-EO7ECE The Electromagnetic Spectrum

 Find the next available page in your notebook  Label the page 6.P.3.2 Electromagnetic Spectrum  Add this entry into your notebook also

 Our new standard:  Explain the effects of electromagnetic waves on various materials to include absorption, scattering, and change in temperature

 Add this statement to your notebook…  Roxy May Is Victorious Using X-box and GameCube

 R= radio  M= microwave  I = infrared  V = visible  U = UV  X = X-ray  G = gamma

 You will be:  Assigned to work in a group of 2 or 3 students.  Research 1 of the 7 parts of the spectrum.  You will receive a handout now to help organize your ideas.  Research, create a poster, and present your findings to the class

 You will:  Use the articles I provide to you.  Use the yellow textbook section on the electromagnetic spectrum

 Your presentation should last 2-4 minutes.  You will share your research, report your findings and present your poster

 Type in culler science weebly (in a search box)  Select Electromagnetic Waves  Investigate activities 1 – 3 for information related to your specific region of the spectrum

 Your group will get the following items to help you conduct your research..  A chromebook  A yellow textbook  A handout to record your research findings  An informational packet related to your region of the spectrum  Art supplies (colored pencils and paper)

 I want to see your best!

 1. Electromagnetic radiation is a form of energy; it has no mass.  2.Electromagnetic waves differ from other waves (sound waves, for instance) in that they do not need a medium to transfer their energy— they move through a vacuum.

 3. Electromagnetic radiation moves at the speed of light (300,000 km/sec).  4.Electromagnetic radiation can also be described in terms of massless particles called photons.

5. Electromagnetic radiation is given off whenever atoms are energized. 6. The various forms of electromagnetic radiation differ only in wavelength and frequency; they are alike in all other respects.
