SCIENCE QUESTIONS:

5. When a wave transmits, or transfers, energy, do the individual molecules or particles also move from one end to the other?

6. How does a sound travel from a vibrating rubber band reach your ear (do the air molecules first touched by the rubber band travel across the room to hit your ear)?

Day 2 Section
Speed of Sound:
7. How can the speed of sound be measured?

8. Do all substances transfer sound waves the same?

9. List the materials in order, from which material can carry sound the fastest, to which carries it the slowest:
Fast: , , slow

10. How does the temperature of air affect the speed at which sound travels through it? Why?

11. Why can’t sound travel in outer space?

12. Through which material would you hear a sound faster if someone were to tap the other end with a hammer: if you place your ear on the end of a long wooden plank or at the end of a long aluminum plank?

Sound and Hearing:
13. Briefly describe how a sound is transferred from its source to be received by the brain:

14. What parts of the ear are involved in conductive hearing loss, and why?

15. What is sensorineural hearing loss?

Day 3 Section
Wave Energy and Amplitude:
16. For sound and other mechanical waves, the amount of wave energy is related to its and its .

17. What is the definition of amplitude?

18. In a sample of air, how does a lower amplitude differ from a higher amplitude?

19. Will the wave traveling through air represented by the sample on the left or the right sound louder? Why?

20. What are two ways to increase the energy of a wave?

Extending the Senses:
21. What is sonar used for, and how does it work?

22. What is a seismograph used for, and how does it work?
