Science Process Skills Science Process Skills Presentation Transcript

  • Science Process Skills
    • Logical operations of thinking in
    • investigations. They are either basic or
    • integrated.
    • Basic Process Skills : Observing, comparing, classifying, quantifying, inferring, predicting, communicating and manipulative skills.
    • Integrated Process Skills: Embodied in experimenting which includes hypothesizing, controlling variables and classifying data .
  • The Basic Process Skills
  • 1. OBSERVING
    • most basic and fundamental of the process skills. One cannot compare, classify or perform the other process skills without being a good observer. We observe objects or events through our five senses: sight, smell, touch, taste and hearing.
    • Example: Describing a pencil as yellow
  • The Process of observing can be:
    • Qualitative – this is identifying and naming the properties of an object such as its shape, color, size, texture, smell, and sound.
    • Quantitative – This kind of observation involves measurement.
    • Change – it could be the result of crushing, pounding, burning, cutting, decaying, etc.
  • 2. COMPARING
    • Comparing is using observable properties in discovering similarities of and differences between objects and phenomena. Through comparison, we are able to identify relationships among objects and phenomena observed.
  • 3. CLASSIFYING
    • There is an overwhelming number of things around us – nonliving and living things. Order can be attained by observing similarities, differences and interrelationships and by grouping them accordingly to suit some purpose.
    Example: Placing all rocks having certain grain size or hardness into one group.
  • 4. INFERRING
    • While observing is getting information by using one or more senses, inferring is explaining or interpreting an observation.
    Example: Saying that the person who used a pencil made a lot of mistakes because the eraser was well worn.
  • 5. PREDICTING
    • Predicting is the process of using past observations or data along with other kinds of scientific knowledge to forecast event or relationships. A statement not based on observation is not a prediction. It is simply a guess.
    • Interpolation – is predicting new data based on and within a trend/ pattern of previously observed data.
    • Extrapolation - is predicting new data outside or beyond the range of previously observed data.
  • 6. QUANTIFYING
    • Quantifying is making and manipulating quantitative observations.
    • This involves:
    • 1. Using numbers
    • 2. measuring
    • 3. using time and space
    Example: Using a meter stick to measure the length of a table in centimeters.
  • 7. COMMUNICATING
    • Expressing ideas in many forms, such as orally, in writing or with graphs, diagrams, tables of data or photographs is a way of communicating.
    Example: Describing the change in height of a plant over time in writing or through a graph.
  • 8. MANIPULATIVE SKILLS
    • These skills involve using equipment and materials properly and accurately, preparing setups for investigation, and handling specimen carefully.
