Transcript

  • 1. Introducing science Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding1. It is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions.
  • 2. What is technology?
    • Technology is the process by which humans modify nature to meet their needs and wants. Most people, however, think of technology in terms of its artifacts: computers and software, aircraft, pesticides, water-treatment plants, birth-control pills, and microwave ovens, to name a few. But technology is more than these tangible products.
  • 3. Benefits of technology .
    • Man, powered by his imagination and inquisitive character, has wondered he mechanisms of Nature since time infinite. This quest for the truth, the ways in which his surrounding works, has led to many a scientific discoveries and innovations. Since the art of making fire and creating handcrafted tools, our civilization has come a long way. Science and Technology are making advances at an amazing rate. From telephones to the Internet, calculators to computers, cars to rockets and satellites, we are submerged in a sea of discoveries and inventions made possible by Science. Fields like Medicine and communications have made inroads into our cultures and thus our lifestyles
  • 4. Abuses of technology
    • Advancements in science and technology have made our life a lot easier. However sometimes they can cause harm to society and the environment, especially when misused.
  • 5. Can technology solve all our problems?
    • There is a broad agreement among psychologists that the term “problem“ refers to a situation in which an individual is called upon to perform a task not previously encountered. Moreover, when dealing with a true problem, externally provided instructions do not specify completely the mode of solution. The particular task, in other words, is something new to the individual, even though the processes or knowledge already available can be called up for solution. (Resnick & Glaser 1976)
  • 6. Hazard symbols Hazard symbols are easily recognizable symbols designed to warn about hazardous materials or locations. The use of hazard symbols is often regulated by law and directed by standards organizations . Hazard symbols may appear with different colors, backgrounds, borders and supplemental information in order to signify the type of hazard.
