Basics Steps of Scientific Investigation

  1. Identifying problem
  2. Making hypothesis
  3. Plannig the investigation
  4. Identifying and Controlling Variable
  5. Conducting the experiment
  6. Collecting and recording data
  7. Analysing and interpreting data
  8. Making conclusion
  9. Preparing the report


The 2 main scientific skills

  1. Science process skill (Mental skill)
  2. Manipulative skill (Hand skill)


The 6 Science Process Skill (OCCMIP)

  1. Observation
  2. Communication
  3. Classification
  4. Measurement
  5. Inference
  6. Prediction


Examples of Manipulative Skill

  1. Handling apparatus and material correctly.
  2. Handling specimen correctly
  3. Clean apparatus correctly
  4. Storing apparatus and reagents correctly


Hypothesis

Hypothesis is a suggested explanation for a specific phenomenon.

Inference

Inference is the act or process of deriving a conclusion based on what one already knows.
