27
Q

Name the steps in scientific method

A
Observation
Hypothesis
Experiment
Data
Conclusion 
Relating the conclusion to existing knowledge
28
Q

Name the reasons for experiments to be fair

A

Sample size
Random selection
Double blind testing
Replicates

29
Q

Sample size

A

Normally as large as sample as possible is tested for more reliable results

30
Q

Random selection

A

To prevent bias (unfairness) by the person carrying out the experiment

31
Q

Double blind testing

A

Prevents person carrying out experiment from unconsciously influencing the results

32
Q

Replicated

A

Repetition of a test/ complete experiment

33
Q

Name the four principles of experiments

A

Careful planning and design
Ensure experiment is safe
Design a control experiment
Experiments must be fair

34
Q

Explain extent of our knowledge

A

The ability to form a hypothesis and design an experiment is dependent on the amount we know relating to our observations
