  2. Can We Talk?100 • The use of echoes to help animals find their way and food is called…. • Echolocation Return to board

  3. Can We Talk? 200 • Any sounds that are too high for humans to hear are called… (hint: machines can send out these high frequency waves and then make a picture of the echoes) • Ultrasound Return to board

  4. Can We Talk? 300 • Sounds below the human hearing range are called….. (hint: elephants make sounds this low) • Infrasound Return to board

  5. Can We Talk? 400 • This common household machine turns sound energy into electrical energy and then back to sound again. • Telephone Return to board

  6. Can We Talk? 500 • This device measures how long it takes for an echo to return. It is generally used by submarines and fishing boats to determine the object’s distance. • Sonar Return to board

  7. I Can’t Hear You100 • This part of the outer ear contains ear wax…. • Ear Canal Return to board

  8. I Can’t Hear You 200 • Name the 3 small bones of the middle ear…. • Hammer, Anvil, Stirrup Return to board

  9. I Can’t Hear You 300 • A thin, tight membrane that vibrates…….. • Ear Drum Return to board

  10. I Can’t Hear You 400 • This inner ear structure contain fluid which vibrates tiny hair cells…. • Cochlea Return to board

  11. I Can’t Hear You 500 • Which nerve carries electrical signals to the brain? • Auditory Nerve Return to board

  12. Play It Again100 • A measurement of how high and squeaky or low and deep a sound is…. • pitch Return to board

  13. Play It Again 200 • A measure of how many compressions pass a certain point every second. • Frequency Return to board

  14. Play It Again 300 • Frequency is measured in a unit called…. • Hertz (Hz) Return to board

  15. Play It Again400 • The distance from the top, or crest, of one wave to the next is called…. • Wavelength Return to board

  16. Play It Again500 • As an object making a sound moves, the pitch changes (think of a motorcycle coming toward you, then passing you). This is called… • Doppler effect Return to board

  17. Too Much Noise!100 • What well-known kids toy is often used to show how a sound wave moves? • Slinky Return to board

  18. Too Much Noise! 200 • A measure of how loud or soft a sound is. Loud sounds have a lot of energy or ….. • Volume Return to board

  19. Too Much Noise! 300 • The height of a sound wave is its …. • Amplitude Return to board

  23. Sound Energy 400 • The pushed-together part of a wave is called a …. • Compression Return to board

  24. Sound Energy 500 • Most wave energy travels in up-and-down waves, not like sound waves. These waves like radio, TV, microwaves, and UV waves are called…. • Transverse waves Return to board

  25. Sound Energy 100 • Sound energy is caused by back-and-forth shaking movements called…. • Vibrations Return to board
