  • Science is a systematic study that is concerned with facts and principles, and methods that could be observed in our natural or physical and social environment
  • Science
    Comes from the Latin word 'scire' that means 'to know'
  • Science
    • It is both a body of knowledge and a process – a way of thinking, a way of solving problems
  • The Branches of Science
    • The Physical Sciences
    • The Earth Sciences
    • The Life Sciences (Biology)
  • Physics
    The study of matter and energy and the interactions between them
  • Chemistry
    The science that deals with the composition, properties, reactions, and the structure of matter
  • Astronomy
    The study of the universe beyond the Earth's atmosphere
  • Geology
    The science of the origin, history, and structure of the Earth, and the physical, chemical, and biological changes that it has experienced or is experiencing
  • Oceanography
    The exploration and study of the ocean
  • Paleontology
    The science of the forms of life that existed in prehistoric or geologic periods
  • Meteorology
    The science that deals with the atmosphere and its phenomena, such as weather and climate
  • Botany
    The study of plants
  • Zoology

    The science that covers animals and animal life
  • Genetics
    The study of heredity
  • Medicine
    The science of diagnosing, treating, and preventing illness, disease, and injury
  • Scientific Method
    1. Identify and clearly state the problem
    2. Gather information pertinent to the problem
    3. Formulate hypothesis
    4. Test the hypothesis
    5. Draw a generalization or conclusion
    6. Apply the principle (conclusion) to other situations
  • Phenomenon
    A thing observed by the senses
  • Fact

    A scientifically tested observation
  • Controlled experiment
    • Manipulating one of the conditions or factors that may affect the result of experiment
    • Trials - number of times experiment is repeated
    • Controls - factors that are kept constant throughout the experiment
    • Variables - factors that change during the experiment
  • Independent or experimental variable

    Factors that are changed
  • Dependent variable
    Factors that change as a result of changes in the independent variable
  • Conclusion
    A statement about the result of the experiment
  • Law
    A statement which describes what happens but does not explain the cause of the occurrence
  • Theory
    Hypothesis that can be explained from observations
  • Scientific Traits
    • Curiosity
    • Logic and system
    • Open-mindedness
    • Intellectually honest
    • Hardwork and perseverance
    • Not opinionated
    • Creativity and critical thinking
  • Technology
    The application of scientific knowledge to practical purposes
  • Types of Technology
    • Machines
    • Products
    • Processes
  • Measurement
    The process of comparing a quantity with a chosen standard
  • Basic Quantities in the International System (SI) of Measurement
    • Length
    • Mass
    • Time
    • Electric current
    • Temperature
    • Amount of substance
    • Luminous intensity / light
  • Two factors affect the degree of measurements: (a.) the ability to use the measuring instruments properly and (b.) the precision of the instrument
  • Unit factor method
    A systematic technique for solving numerical problems by cancelling units not desired using fixed relationships, leaving behind the unit desired
  • Metric Prefixes
    • giga
    • mega
    • kilo

    • centi
    • milli
    • micro
    • nano
    • pico
  • Fahrenheit temperature scale
    Based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts
  • Celsius temperature scale
    Based on 0 for the freezing point of water and 100 for the boiling point of water
  • Metric prefixes
    Like 'kilo' and 'milli', they are very handy for understanding metric conversions
  • Temperature scales in use today
    • Fahrenheit
    • Celsius
    • Kelvin
  • Centigrade temperature scale
    Scale based on 0 for the freezing point of water and 100 for the boiling point of water
  • Kelvin temperature scale
    The base unit of thermodynamic temperature measurement in the International System (SI) of measurement, defined as 1/273.16 of the triple point of pure water
  • Converting Celsius to Kelvin
    K = °C + 273
  • Volume
    The amount of space that an object occupies
