Grade 5

You might use the Internet to look up average temperatures and extend this Headline Story. Students might consider the difference between the hottest and coldest temperatures on Mount Everest, for example.

Susan claims that the average temperature decreases by 3^{o}F for every 2,000 feet of elevation on Mount Everest. If she were correct, what would be the temperature at 29,000 feet if the temperature at the base camp at 17,000 feet is _____^{o}F.

- If the base camp was 50
^{o}F, 29,000 feet would be 32^{o}F. - If the temperature at the base camp was 0
^{o}F, the temperature at 29,000 feet would be –18^{o}F. - There would be a difference of 18
^{o}F between base camp and 29,000 feet. - The temperature at 21,000 feet would be 6
^{o}F less than at base camp.
