Berikut merupakan hasil pembelajaran kami pada hari tersebut :

Science Process Skills

  • Involves in scientific investigation
  • As ways in producing and arranging information about our world
  • Basic – basic & provide foundation
  • Integrated Skills – complex skills

Basic Skills

  • Observing
  • Classifying
  • Measuring and Using Numbers
  • Inferring
  • Predicting
  • Communicating
  • Using Space-Time Relationship

Integrated Science Process Skills

  • Interpreting Data
  • Defining Operationally
  • Controlling Variables
  • Hypothesising
  • Experimenting

Observation

  • Using one or more senses to gather information qualitatively
  • The five senses are sight, smell, touch, taste, and hearing
  • Equipment may be used to make data accurate and precise. Eg. the use of ruler, thermometer
  • Information gain leads to curiousity, questions, interpretations and further investigation
  • For development to other skills such as inferring, communication, predicting, and classification

Berikut merupakan hasil pembelajaran kami pada hari tersebut :

Measuring and Using Numbers

  • A quantitative observation using equipment
  • Correct way of taking the measurement

Classifying

  • Grouping or ordering objects or events according to a classification scheme or patterns
  • Based on similarities, differences and interrelationships
  • Scientist classify for the purpose of study

Inferring

  • Ideas developed or explanation made based on observations
  • Appreciate better if we are able to interpret and explain things happening around us
  • Scientists form hypotheses based on inferences

Examples …

  • There is a spot in my front yard where grass does not grow
  • I see that iodine turns purple when put it on a potato chip
  • That star is brighter than the others

Predicting

  • Forming an idea or making a forecast based on a certain set of data
  • Closely related to observing, inferring, and classifying
  • Classifying involves ordering or sequencing. It permits us to recognize patterns and to predict from the patterns what future observation will be.

Communicating

  • Giving or exchanging information with others, in the form of verbal, written, diagrams, graphs, tables, or other forms of visual demonstration

Using Space-Time Relationship

  • Describing changes in parameter with time. Examples of parameters are location, direction, shape, size, volume, weight and mass.

Interpreting Data

  • Giving rationale explanations about an object, event or pattern obtained from the collected data
  • What does the data tell

Defining Operationally

  • Defining terms within the context of one’s own experiences; stating a definition in terms of “what you do” and “what you observe”
  • Example: Endurance of a person

a.  the number of hours a could stay awake

b.  the distance a person could run without stopping

c.  the number of jumping jacks a person could do

Examples

  • Complete circuit is a bulb, dry cell and wire connected so the bulb lights up
  • A legume  bears its seeds in pods
  • A carbohydrate turns blue-black when a drop of iodine is placed on it

Controlling Variables

  • A variable is something that varies or changes. Controlling variables is manipulating one variable or factor that may affect the outcome of an event while other variables or factors are held constant

Hypothesising

  • Stating a problem to be solved as a question that can be tested by an experiment. Hypotheses are intellectual guesses about the relationships between variables

Experimenting

  • Setting up a planned situation and using most of the science process skills to collect and analyze data to draw conclusions in order to test the hypothesis or to solve a problem

Manipulative Skills

  • Psychomotor skills
  • Use and handle science apparatus and substances
  • Handle specimens correctly and carefully
  • Draw specimens and apparatus
  • Clean science apparatus
  • Store science apparatus
