A problem early in the century was cooling and drying the air. Much of the South was unlivable, because of heat and humidity. Many people sweltered in the hot summers, and many died of heat exhaustion. Engineers like Willis Haviland Carrier changed all that. After many experiments, Mr. Carrier figured out that chilling air with water to condense it could also dry it. The first machines were used to condition air in factories – to improve the quality of products that didn’t do well in heat and humidity. Today, we can live, work and play in any climate. All because inquisitive engineers believed that we could live comfortably even in the hottest climates.
Lesson Synopsis: Students attempt to delay the melting of an ice cube by insulating it, consider the importance of purchasing energy efficient products, and design a subdivision where home cooling costs are reduced.
