1
Science and Technology
  • Glencoe Chapter 2 Section 1
  • Integrated Science
  • Pages 38-45

2
A. Scientific Discovery
  • - History is full of breakthroughs in science
    that have changed the course of human history.

3
Types of Discoveries
  • Some discoveries were through scientific
    experiments, and others were by random chance or
    out of necessity.
  • For example
  • - Fire for cooking and heat was by chance
  • - Wearing animal skins to stay warm was by
    necessity
  • - Early medicine with roots and plant parts was
    a bit more scientific

4
Examples of Scientific Insight
  • 1. Disease Prevention Today
  • - Measures are taken now because we know how
    contagious diseases are spread from person to
    person and what causes infections in wounds.

5
Examples of Scientific Insight
  • 2. Weather Forecasting
  • - Meteorologists use a variety of specialized
    instruments to predict the weather.

6
B. What is technology?
  • - Science is an exploration process.
  • - Technology is the application of scientific
    knowledge of materials and processes to benefit
    people or to meet a human need.

C. Global Technological Needs
  • - Developing countries
  • Technological solutions focus on
  • supplying basic needs for families.
  • Technology that would supply adequate
  • and safe drinking
  • water and food
  • supplies would
  • be valued.

10
C. Global Technological Needs
  • - Industrialized Countries
  • ? Because the needs for survival are met in
  • industrialized nations, money often is
  • spent on
    technology.
  • ? Technology is designed to
    improve the quality of life of
