CBA 1 - Extended Experimental Investigation (EEI)
CBA 1 is completed in 2nd Year
This CBA is completed over the course of three weeks. Students engage in four activities which contributes to the generation of their evidence of learning and achievement in the EEI.
These four activities include:
A. Questioning and predicting B. Planning and conducting
C. Processing and analysing D. Reflecting and reporting
A. Questioning and Predicting
Students may work individually or collaboratively in small groups for this part of their investigation.
• Choose the topic
• Decide the research question
• Collect information on the background theory related to the research question
• Refine the question to help with the justification of their hypothesis/prediction
• Record the sources of information
• Write the hypothesis/prediction
B. Planning and Conducting
Students may also work individually or collaboratively in small groups for this part of their investigation.
• Hands-on experience in the laboratory to plan and refine experimental design
• Deciding on an equipment and what materials will be necessary
• Assessing any possible risks
• Writing individual Investigation Plans
• Submitting individually for investigation approval
• Conducting the investigation
• Recording all data as well as problems and changes to method used during any trials and during the final experiments
C. Processing and Analysing
Students must work individually for this.
• Analyse their own data
• Perform any necessary calculations
• Consider how to best represent and analyse their data
• Identify patterns and relationships in the data
• Explain any anomalous data
• Describe the relationships between the variables
• Draw conclusions
• Consider if their hypothesis or prediction has or has not been supported
D. Reflecting and Reporting
Students may work individually or in groups to reflect on their work.
They should critically discuss various aspects of their investigation, such as:
• Experiment design and possible improvements
• Limitations of their data
• Possible theoretical or practical implications of their findings
• Further related investigations that they might conduct
Students will individually report their research and findings in a format of their choice.
If a typed or hand-written report is the format of their choice, the total length of the report would typically be in the 400 - 600 words range (excluding tables, graphs, reference list and research records), but this should not be regarded as a rigid requirement.
