The video introduces STS 10 (Science, Technology, and Society) and outlines the lesson objectives: tracing the historical development of science and technology both globally and in the Philippines, and discussing their societal impact.
The term "science" originates from the Latin word 'scientia' meaning knowledge, defined as a systematic attempt to discover facts through observation, reasoning, and experimentation. "Technology" comes from the Greek 'technique' (art or craft) and 'logos' (word/speech), initially meaning discourse on arts, and later defined as the means by which humans change or manipulate their environment. Science, in its simplest form, has existed since the dawn of human existence, with early people observing nature for practical purposes.
Prehistoric science involved inferential knowledge. Early humans deduced the earth was flat, observed seasonal changes relative to the sun, and recognized distinctions between living and non-living things. They also practiced instinctive therapeutics and had elementary toxicology knowledge to avoid poisonous plants.
The Stone Age is marked by the use of primitive stone tools, with early humans as nomadic hunter-gatherers. Tool-making advanced from simple sharpened stones by Neanderthals to more complex 'hafting' by Cro-Magnons. The Neolithic Revolution, or agricultural revolution, marked the transition from nomadic life to settled agricultural communities, driven by climate changes and intellectual advances. This revolution began in the Fertile Crescent, leading to the rise of civilizations.
Mesopotamia, located between the Tigris and Euphrates rivers, facilitated agricultural production and early civilizations. The Sumerians, considered creators of civilization, explored scientific hypotheses, innovated technologically, and created writing (cuneiform), mathematics, astronomy, astrology, and the concept of time. Their most important inventions include the wheel, the sail, and writing. They also developed irrigation systems and invented the plow.
Babylon was a powerful city that nurtured scientific thought. Babylonians developed astronomy and astrology, seeing them as intertwined. They associated planets with deities and used observatories for reports to the king, influencing decisions on agriculture, diplomacy, and war. They were also mathematicians, inventing fractions, cartography, jewelry making, and a calendar system. Their sexagesimal number system provides the basis for modern time and degrees in a circle. They created the world's first map and a lunisolar calendar.
Ancient Egyptian civilization flourished along the Nile River due to its annual flooding. The Egyptians excelled in science and technology, building monuments, temples, and inventing practical items like paper, ink, cosmetics, toothbrushes, toothpaste, and breath mints. They made advances in engineering, construction, agriculture, architecture, medicine, astronomy, and art. Their writing system, hieroglyphics, began with pictograms and evolved to include phonetic symbols. They also developed papyrus for writing material, and practiced embalming (mummification).
Astronomy was vital for ancient Egyptians, serving both spiritual and practical purposes. They used stars to track seasons for agricultural planning and improved their calendar. Egyptian medicine combined magic with significant medical knowledge, as evidenced by papyri detailing treatments and spells.
