Resources - The materials required to complete this assessment will be provided to students where they can be safely transported by mail or collected directly from the school. Where materials cannot be provided by the school, students may be required to source their own materials or modify their methodology.
Other resources include online research, data bases and journals.
Context
You have completed the following experiments in class:
- Conduct an experiment and collect quantitative / qualitative data to determine the horizontal distance travelled by an object projected at various angles from the
- Conduct an experiment and collect quantitative / qualitative data to investigate the strength of a magnet at various distances.
- Conduct an experiment and collect quantitative / qualitative data to investigate the force acting on a conductor in a magnetic field.
Task
- Modify (i.e refine, extend or redirect) an experiment in order to address your related research question.
- You may use a practical performed in class, a related simulation or another practical related to Unit 3 (as negotiated with your teacher) as the basis for your methodology and research question.
To complete the task, you must:
- Identify an experiment to *
- Develop a research question to be *
- Research relevant back ground scientific information the modification of the research question and methodology.
- Conduct a risk assessment and account for risks in the *
- Conduct an *
- Collect sufficient and relevant qualitative and quantitative data to address the research question.*
- Process data and present the data
- Analyse the evidence to identify trends, patterns or
- Analyse the data to identify uncertainty and
- Interpret the evidence to draw conclusions to the research
- Evaluate the reliability and validity of the experimental
- Suggest possible improvements and extensions to the
- Communicate findings in an appropriate scientific genre, e scientific report.
*The steps indicated with an asterisk above may be completed in groups. All other elements must be completed individually.
Checkpoints
- Week after Handout: Select experiment and identify proposed Develop research question and complete risk assessment.
- Weeks after Handout: Perform experiment and process data
- Weeks after Handout: Analyse and evaluate
- Weeks after Handout: Evaluation of evidence
- Weeks after Handout: Submit draft. 8 Weeks after Handout: Submit final response
Authentication strategies
- Teacher will provide class time for task
- Students will provide documentation of their progress at indicated
- Teacher will collect and annotate one draft
- Teacher will consult with each student as they develop the
- Students will submit the assignment via QLearn and use plagiarism detection software at submission of the response.
- Students must acknowledge all
- Teacher will compare the responses of students who have worked together in
Scaffolding
The response must be presented using an appropriate scientific genre(i.e scientific report) and contain:
- a research question
- a rationale for the experiment
- a reference to the original experiment and identification and justification of modifications to the methodology
- raw and processed qualitative and/or quantitative data
- analysis of the evidence
- conclusion/s based on the interpretation of the
- an evaluation of the methodology and suggestions of improvements and extensions to the experiment
- a reference list
An example of how one of the practicals could be modified to develop a research question.
Practical that will be modified: conduct an experiment to investigate the parallel component of the weight of an object down an inclined plane at various angles.
Research question: What is the relationship between the angle of inclination and the magnitude of the frictional force for a given rectangular wooden object on a given wooden surface?
Develop the research question
Note: You can not use this sample research question for your experiment.
