GENERAL CONCEPTS OF SCIENCE AND TECHNOLOGY Scientia - knowledge Science: Idea Intellectual Activity Body of Knowledge Personal and Social Activity Thus, science is a process of investigation into the natural world and knowledge generated through that process. Scientific Method: process of objectively establishing facts through testing and experimentation. Observation Question Hypothesis Experiment Analysis Conclusion Technology: applied science. It is a collection of techniques, skills, and methods in the accomplishment of the scientific investigation. It is the application of scientific knowledge for practical purposes, especially in industry.) Process of finding solutions to human problems to make life easier and better. Changes the environment and society. Advantages of Science and Technology in Society Life became easy and comfortable. Travelling has become easy and fast. Communication became cheaper/ easier. Standard of living has increased with the increase in technology. Help treat more sick people and save many lives and fight against harmful viruses and bacteria. Disadvantages of Science and Technology in Society It can be easily manipulated by irresponsible people. We’ll be too dependent on it. It affects our health and lifestyle. Terrorists are using modern technology for their destructive work. It destroys our natural world.
