Module 6 Introduction

Aircraft technicians apply de-icers and anti-icers to airplane wings, fuselages, and tail sections to remove ice, frost, and snow. These substances inhibit ice formation by lowering the freezing point of water. The amount of substance applied will depend on the aircraft's surface area.

 

In Module 6 you will explore the surface area of three-dimensional objects. In particular, you will investigate surface areas of spheres, cylinders, cones, and prisms, and you will apply these skills in a variety of practical problem situations.

 

Another winter pursuit similar to de-icing aircraft is ice and snow removal from streets, parking lots, and highways: the focus of the Module 6–7 Project. This project will combine your study of surface area in this module with your study of volume and capacity in Module 7.

 

In this module you will investigate the following question:

  • How does an understanding of surface area help to solve problems in a variety of contexts?
