Practical notes
1. The aim or purpose of an investigation
1. = describes what the experiment is trying to find out.
1. Format example: To investigate ...
2. Investigative question
2. An investigation usually starts with this.
2. It is a question where the dependant and independent variable are mentioned.
2. NOTE - Ask a question about their relationship, where the answer cannot be yes or no.
2. Format example: What is the relationship between Dependant Variable and Independent
2. Variable?
3. Hypothesis
3. = A supposition, i.e. what you suppose the result will be.
3. The dependant, independent and a value, including the unit, will appear in your hypothesis.
3. Format example: The Dependant Variable is directly proportional to the Independent Variable.
Variables:
Variables
= Things that can change during an investigation.
Independent variable
= The variable that you will change during the investigation.
There can only be one.
Dependant variable
= The variable that you measure during the investigation.
There can only be one.
Control variable
= The variables that must be kept constant during an investigation in order for the investigation
= to be a fair test.
There are usually many.
When listing control variables:
a. Mention only the most important variables.
b. Describe how you ensured that they remained constant.
