Basics of Science Quiz

What is Science?

• Science involves studying natural phenomena and events, sparked by human curiosity and inquiry.
• It utilizes systematic methods such as observation, experimentation, and analysis to build knowledge.
• Applied scientific knowledge helps solve everyday problems, exemplified by refrigeration which slows down the growth of microorganisms responsible for food spoilage.

Branches of Science

• Biology: Examines living organisms and their interactions.
• Physics: Investigates matter, energy, and forces.
• Chemistry: Focuses on substances, their properties, structures, and reactions.
• Astronomy: Studies celestial bodies and the universe.
• Geology: Explores Earth's structure and rocks.
• Medicine: Concerns the study and treatment of diseases.

Nature of Science

• Evidence-Based: Scientific ideas must be supported by empirical evidence, as demonstrated by Galileo's experiment refuting Aristotle's long-held belief about the speed of falling objects.
• Subject to Change: Scientific knowledge can evolve with new findings. Barry Marshall's discovery of bacteria leading to effective gastric ulcer treatment illustrates this adaptive nature.
• Limitations: While science has advanced understanding, it cannot answer all questions, such as the existence of life on other planets or how to fully cure cancer. Moreover, scientific knowledge does not address ethical dilemmas or personal values.

Application and Impact of Science

• Scientific Discoveries: Advancements in science have led to discoveries that enhance understanding of the natural world, like the discovery of microorganisms.
• Inventions: Technologies such as microscopes have facilitated discoveries and led to creations like pharmaceuticals for disease treatment.
• Modern inventions, including light bulbs, smartphones, vaccines, and motor cars, have significantly improved quality of life and influenced daily living.
