lesson 1

• Science and technology indeed play major roles in the everyday life
• They make difficult and complicated tasks easier and allow people to do more with so little effort and time
• The developments in this field are not just products of people's imagination, they are also brought about by gradual improvement to earlier works from different time periods
• Driving force behind continuous progress or development

  Desire to raise the quality of life of the people
• Let us take consideration to the real situation of human's health effects of these various development of technologies, their relationship to others, and the globally impact to the environment
• Science


  The system of knowledge of the natural world gained through the scientific method
• Science

  • Philosophers of nature tend to understand the natural world and have the ability to name and classify the objects found in nature was seen as the first step towards knowledge
• The scientific search for truth early on recognized the usefulness of language and the ability it gave to describe, classify and explain the different objects of study
• Science


  A systematized body of knowledge based on facts, gathered through observation and experimentation formulated by theories and laws
• Technology


  Practical applications of what we know about the nature using the scientific principles for the betterment of the human situation
• Technology and its corresponding areas of Science

• Inventions of writing


  • Pictographs
  • Lopograms
  • Syllabic writing
  • Alphabetic writing
• The invention of writing greatly helped in the development of science
• Transportation was significant during ancient times because people were trying to go places and discover new horizons
• Navigation assisted them in their journeys to unfamiliar and strange areas in the world and it allowed them to return home after they discovered new places or completed an important trade with another group of people
• Reasons why people go to places using transportation

  • Search for food and find better locations for their settlements
  • Trade their surplus goods in exchange for things that they lacked necessities
• People needed to form a technology that would enable them to increase food supplies and other survival needs without them travelling more or working harder
• As they discovered new places, the development of weapons and armors for their security and protection
• The primary challenge they faced was the conservation of life. Different illnesses and diseases, both natural and man-made, hampered the full potential of human being
• Science and technology played a major role in the discovery of cures if not, the prevention of illnesses
• Communication was also essential in their endeavors to discover and occupy new places. They needed a way to communicate with natives of the areas they visited so as to facilitate trade and prevent possible conflicts
• Record-keeping was also important since they needed to remember the places they had been to and document the trade they made with each other
• It was also vital to keep records of their history and culture so they could establish their identities as they tried to relate with other cultures and civilizations
• The development of engineering allowed human to build structures that would address their specific needs and wants
• Elaborate architectural designs were signs of technological advancements of a particular civilization
• People were not contented on beautifying only their infrastructures and surroundings. They discovered that people looked more visually presentable and appealing by adding some features and decorations in their body
• Cuneiform
