Scientific Investigation in Chemistry (4)

Definition of hypothesis

Is a general statement to relate a manipulated variable and responding variable to explain the question that has been asked

Scientific Method (7)

The manipulated variable, responding variable and fixed variable in an experiment are identified to test the hypothesis

Definition of manipulated variable

A factor which is purposely changed during the experiment

Definition of responding variable

A factor that responds to the change of manipulated variable

Definition of fixed variables

Factors which are kept the same throughout the experiment

Scientific Method (8)

Decide on how to change the manipulated variable, to measure the responding variable and to keep the fixed variables

Scientific Method (9)

Determine the apparatus and materials used, procedure of experiment and ways to collect, analyze and interpret data

Scientific Method (10)

Then, an experiment is carried out to test whether the hypothesis formed can be accepted or rejected

Scientific Method (11)

Making observation, measurement and record all the results or data accurately and systematically

Scientific Method (12)

Analyse the results or data collected and interpret them through calculation, table, graph or chart
