Practical investigation questions
Aim
Starts with ‘to’
Example; to determine the brightness of a bulb when connecting more cells
in series
Investigation question
Has a question mark and cannot be answered with yes or no. the question
must include variables; what will be changed and what remains the same.
Example; how will the brightness of the bulb change id more cells are
connected in series?
Hypothesis
What you think the answer to the investigation question will be
Example; The brightness of the bulb will increase as more cells are
connected in series
Variables
• Independent variable
What will change during the investigation
Example; the number of bulbs
• Dependent variable
What will be measuring during the investigation
Example; the brightness of the bulb
• Constant variable
What will remain the same during the investigation
Example the light bulb
Observation
What you observe
Example; the bulb glows brighter when the number of cells in series
increases
