  1. Access Prior Knowledge Lesson 2: What is sound energy? Opening Activity Open Science textbook to page 454. Open Workbook to page 140A to check homework. Open Science folder to review vocabulary words and outline for the chapter. Open Science journal and answer the following questions: 1-Explain what potential and kinetic energy is and give examples of each? Review Content Cards and Q-Cards in bin, sharing with partners quizzing each other quietly. Log in to clickers using student ID number. Be ready to review home learning when timer goes off. Don't forget to write your home learning in your agenda page 141A.

  2. Do you agree with the statement? The vibrations in materials are responsible for making different sounds. YES NO

  3. Do you agree with the statement? The lower the frequency of the wave, the higher the pitch of the sound. YES NO

  4. Do you agree with the statement? Decibels are used to measure a sound’s intensity. YES NO

  5. Do you agree with the statement? When the energy of sound waves is transferred, it becomes electrical energy. YES NO

  6. What is Sound? Sound is a wave of vibrations (back-and-forth motions) that spread from their source and is measured in decibels. A sound with greater frequency (measure of how fast particles vibrate), the higher the pitch. The areas where the particles are close together are called the crest. The part of the ear that absorbs the sound is the eardrum.

  7. Your Voice Energy causes the vocal cords in your throat vibrate and make sounds (particles vibrate) when you talk and travel in the air as sound waves.

  8. How Does Sound Behave?

  9. Sound Transfer of Energy Sound waves transfer energy from one object to another, like sound in the music room is absorbed by soundproofing material. BRAIN POP: Sound

  10. Waves

  11. TextQuest Answer in your Science Journal 1. What part of the ear absorbs the sound energy? 2. In which material does sound travel the slowest: air, water or metal? 3. In which material does sound travel the fastest: air, water or metal? 4. Where is the crest of the sound waves? Don't forget to write your home learning in your agenda page 141A.
