  • 1. Science Is… Unit 1: An Introduction To Physical Science Part 1 NOTES (Text: Prologue)
  • 2. What?!
    • What do people do when they cannot explain something?
    • What do people do when they do not understand something?
    • Actions usually fall into 3 categories:
      • Science (Physical Data, How?)
      • Arts (Emotions)
      • Religion (Spiritual, Why?)
  • 3. What is SCIENCE?
    • The orderly search for answers to our questions about the world we live in.
    • How do scientists “orderly search for answers to problems and questions”?
    • The questioning is called
    • SCIENTIFIC INQUIRY.
    • The steps of problem solving are called
    • the SCIENTIFIC METHOD.
  • 4. How do scientists work?
    • Questioning/ Inquiry
    • Experimentation
    • Trial & Error
  • 5. SCIENCE: What is the difference between Pure & Applied Science?
    • Pure Science
      • motivated by curiosity
      • Example: PHYSICS
    • Applied Science
      • designed to answer specific questions
      • Example: ENGINEERING
  • 6. Pseudoscience
    • “ pseudo-”
      • is a prefix that means “false”
    • Pseudoscience is a “false science”.
    • Pseudoscience:
      • makes predictions
      • cannot support hypotheses BASED ON DATA.
      • cannot draw valid conclusions BASED ON DATA.
    • Examples:
      • Astrology
      • Some fetal gender predictors
      • Palm Reading
  • 7. Science Skills
    • Analysis
    • Communication
    • Evaluation
    • Experimentation
    • Inference
    • Mathematics
    • Observation
    • Organization
    • Problem Solving
    • Research
    • Scientific Measurement
  • 8. Scientists must be:
    • Accurate
    • Clear
    • Cooperative
    • Curious
    • Expressive
    • Objective
    • Open to discussion
    • Productive
  • 9. Science & Math
    • Science can be described and analyzed mathematically.
    • Math allows scientists to compare measurable data.
  • 10. PHYSICAL SCIENCE
    • PHYSICS-
      • Motion
      • Force
      • Energy
      • Matter
      • Heat
      • Sound
      • Light
    • CHEMISTRY-
      • What is matter composed of?
      • How do molecules combine to form materials around us?
  • 11.
    • To understanding living things, you must understand chemistry.
    • You must understand physics to understand chemistry.
  • 12. Science GONE BAD
    • Salem Witch Trials
    • Blood Letting
    • Many other Past Medical Treatments
  • 13. SCIENCE & TECHNOLOGY
    • What technology do we use everyday?
    • What do we use technology for in Science?
    • Why do we have technology?
  • 14. Good or Bad?
    • What are our general feelings about technology?
    • What are the advantages?
    • What are the disadvantages?
  • 15. Risk Assessment
    • What risks are there in scientific improvements?
    • When do the benefits outweigh the risk?
    • Who decides now? Who should decide?
    • What are ETHICS?
  • 16. What is a THEORY?
    • Scientific Theory:
      • Group of verified hypotheses about certain aspects of the natural world.
      • Theories may change as scientists learn more about the topic.
      • Examples:
        • The Theory of Evolution
        • The Theory of the Big Bang
        • The Theory of Plate Tectonics
  • 17. What is a LAW?
    • Scientific Law or Principle:
      • Something that has been tested over and over again and has not been contradicted.
      • Examples:
        • The Law of Gravity
        • Newton’s Laws
  • 18. Fact & Speculation
    • Scientists rarely say that information is factual.
    • Fact - BASED ON DATA
    • a generally close agreement among competent observers studying the same thing.
    • A fact can be “disproved” if experimental data shows otherwise.
    • Speculation - a statement that cannot be tested to be correct and/ or incorrect.
    • Can you make a speculation?
    • “ Intelligent life exists on another planet somewhere else in the universe”
  • 19. Acceptable Information
    • You cannot test everything. Sometimes you just have to take someone’s word for something.
    • What information is “acceptable”?
  • 20. Criteria for determining if information is “acceptable”
    • Comes from a RELIABLE source.
    • Is TESTABLE.
    • Is NOT funded or conducted by a stakeholder.
  • 21. QUESTIONS?
  • 22. What QUESTIONS will we answer this year?
