1.3 STEPS IN SCIENTIFIC INVESTIGATION

LEARNING OUTCOMES

SCIENTIFIC INVESTIGATION• A scientific investigation : a series of steps

done systematically to study a problem or an event.

• Involves the use of one or more science process skills.– Different types of skills, including thinking &

reasoning skills need for scientific investigation.– Examples : Observing, measuring, making

inferences & controlling variables

The sequence of steps in scientific investigation

Identifying the problemWe determine what we want to find out.

Forming a hypothesisTo make a smart guess to explain the problem.

Needs to be tested.

Planning an experimentIdentifying the variables involved.

Determining the materials & apparatusDetermining the procedure to carry out, methods

of collecting & analysing data

Carrying out the experimentControlling the variables

Collecting data through observations & measurements.

Analysing & interpreting dataExplaining the collected data

Giving an explanation.

Making a conclusionState whether the hypothesis is true.

Based on data.

Writing a report on the experimentWriting a report on the experimentPresent the aim, apparatus & procedure, any table/graph

& conclusion in the report.
