ANALYZE IT

Complete the Analysis Questions in your SDR then discuss them as a class. 

  • Write your calculated speeds of sound for each type of matter in Table B.

  • Refer to the first Background. Based on the Background and your calculated speeds, identify each of the three types of matter as air, water, or iron.
  • In the last column record the identity of each type of matter.
  • Use axes below to make a bar graph that compares the speed of sound in air, water, and iron.

  • Order the three types of matter from the lowest speed of sound to the highest speed of sound. 
  • Which of the three types of matter would have the greatest amount of attraction between its atoms or molecules? 
  • Which of the three types of matter would have the least amount of attraction between its atoms or molecules? 

GET FOCUSED

Complete the Focus Question in your SDR then discuss it as a class. 

  • How do different types of matter affect the speed, the wavelength, and the frequency of sound? 

 

COMPREHENSION CHECK

The Comprehension Check is designed to summarize the CELL.

Answer each Focus Question below. 

  • How are sounds produced?
  • How is sound transferred from one object or substance to another? 
  • What is the relationship between the wavelength and frequency of a standing wave and the sound it produces? 
  • What is the speed of sound in air? 
  • In the same type of matter, is the speed of sound different for different frequencies and wavelengths? 
  • What is the relationship between the wavelength and frequency of a standing wave and the sound it produces? 
  • How do different types of matter affect the speed, the wavelength, and the frequency of sound?
