Scientific Method

Scientific Method-a systematic method used to

solve problems in science.

Scientific Method – 11 steps

1) Making observation 2) Making inference 3) Identifying problem 4) Making hypothesis 5) Identifying variables 6) Controlling variables 7) Planning an experiment 8) Collecting data 9) Interpreting data 10) Making conclusion 11) Writing report

1) Making observation

Gathering information

about a phenomenon using our five

senses, namely sight,

hearing, smell, taste

and touch

2) Making inference

Making a smart guess or tentative explanation about phenomenon based on the observation

3) Identifying problem Asking question (s) base on the

inference made.

4) Making hypothesis Making a general statement about

the relationship between a manipulated variable and a responding variable in order to explain the question asked

5) Identifying variables Identifying the

• Manipulated variable, • Responding variable • and fixed variable of an experiment to test

the hypothesis made

6) Controlling variables Deciding how to manipulate the

chosen variable, what to measure and how to keep the fixed variable(s) constant

7) Planning an experiment Determining what materials and

apparatus to use, the exact procedure of the experiment, the method of collecting data and ways to analyze and interpret the collected data.

8) Collecting data Making observations or measurement

and then recording the data systematically

9) Interpreting data Organising and analysing data. Calculation, graphs or charts may be

drawn to look for any relationship between variables

10) Making conclusion Making a statement about the

outcome of the experiment and whether the hypothesis is accepted or rejected

11) Writing report Communicating the details of the

experiment to spread and find a benefit to the findings
