Sound RAFT

Please do not write on these directions.
Directions: Your task is to work with a partner to complete a RAFT that shows me what you have learned about sound and how it travels. Some key pieces of information that need to be addressed in your RAFT: The speed of sound depends on the elasticity, density, and temperature of the medium the sound travels through. Sound travels slowly in gases (air is a gas). Sound travels more slowly in denser mediums. Sound travels more slowly in lower temperatures than higher temperatures. If you need help getting started, read pg. 39-41 in your book to refresh your memory of how sound travels.
ROLE: Take on the role of a newspaper journalist who has just seen Captain Chuck Yeager of the United States Air Force break the sound barrier. It is the year 1947 and Captain Yeager used his knowledge of how sound travels to become the first person to break the sound barrier flying a plane.

AUDIENCE: Your audience is newspaper readers who are not familiar with the speed of sound. They do not know that sound waves travel at different speeds in different mediums. They do not know that sound travels slower at lower temperatures. They do not know that it is colder at high altitudes than lower altitudes. They have never heard a sonic boom before. Remember, your audience is living in the year 1947.

FORMAT: The format is a newspaper article with photographs (drawings) of the amazing flight. (Your article must be one full page with interesting details. Keep the reader’s attention. Write your article around the ‘photographs’ as in a newspaper.)

TOPIC: The topic is the speed of sound, which depends on the elasticity, density, and temperature of the medium the sound travels through.
