Leaky Bottle Investigation
Introduction/Background information: You will need to introduce the topic and include any relevant
information that helps put the investigation into context about your research question
Research Question: A question in the form of “how does x affect y”. This can be stated before the
introduction/background information if necessary.
Variables: Include your independent, dependent and control variables here. Read the rubric to ensure
you complete these adequately.
Method: This should have an equipment list, a labelled diagram or picture with your experimental set
up and a clear but concise description of how the investigation was carried out. Safety, environmental
and ethical precautions and implications need to be included
