Overview

This lesson consists of two activities linked by classroom discussion. Its purpose is to engage students in the general topic of technology. The first activity involves classroom discussion and a short scenario to allow students to develop a sense of what technology is and to dispel the notion that technology relates mostly to computers. The second activity introduces students to the concept of scale by using the classroom to repre-sent a cell and other smaller objects to represent subcellular components.

Major Concepts

Technology is a body of knowledge used to create tools, develop skills, and extract or collect materials. It is also the application of science (the combination of the scientific method and material) to meet an objective or solve a problem. Scale is a way to represent the relationship between the actual size of an object and how that size is characterized, either numerically or visually.

Objectives

After completing this lesson, students will
  • be able to explain what technology is,
  • recognize that human intervention is the common bond among technologies, and
  • describe the use of scale to distinguish between objects of different size.
