OUTCOME
By the end of the lesson you will have a clear idea of how to create a questions for your EPI and get some ideas of how to develop an investigation to answer that question
In experimental design we think up a question, consider the variables, refine the question, identify the variables and controls and identify the independent variables. We then design an experiment that achieves high recision and accuracy by iteration
LEARNING TASKS
Explain
1. What does refine the question mean?
2. How do we decide which variable is the independent variable?
3. What is the difference between precision and accuracy?
4. How is good data achieved?
Evaluate
You have one week to make a decision on what you will investigate.
Please complete this form with you topic selection. This will include identification of variables to be tested and controlled and ideas of how you may carry the experiment out. this is preliminary as you are now expected to go out and research to create your testable question.
