Scientific Method

Scientific method is a body of technique of acquiring knowledge about the nature and its phenomena.

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

• Science process skill (Mental skill)
• Manipulative skill (Hand skill)

The 6 Science Process Skill (OCCMIP)

• Observation
• Communication
• Classification
• Measurement
• Inference
• Prediction

Examples of Manipulative Skill

1. Handling apparatus and material correctly.
2. Handling speciment 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.

Variable

Variable is a quantity whose value may change in an experiment. It is the parameter that may influence the outcome of an experiment or the data been collected in the experiment.
