Part 2:

The scientific method is a logical and rational way of investigation that helps us to organise our thoughts and procedures and generally we can identify 7 specific steps in this process, these are:

1. Observation

2. Asking a critical question

3. Developing a hypothesis

4. Making a prediction that can be tested

5. Performing experiments to test the prediction

6. Data collecting and analysis

7. Making a logical conclusion based on experimental results

Task: You observe that workers in a large open plan office environment tend to complain of headaches by mid-morning, particularly towards the end of the working week and the absenteeism rate amongst this group is much higher that among other employees.
