PRESENTATION OUTLINE

AIR CONDITIONING

BY: CHRISTIAN MCDOW

Change:
Instead of using fans you use in your hand or using electrical fans, people are now using air conditioners. This has helped us change over time by becoming more modern and thinking of more reasonable and more effective ways to stay cool. Instead of a fan that only keeps one spot cool, we have air conditioners that can keep entire houses cool.

Continent example:
The example I've used for all continents is they have all evolved from electric fans and ceiling fans to air conditioners.

Background Info:
during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902.An air conditioner is a major or home appliance, system, or mechanism designed to change the air temperature and humidity.
