Assessment Type 1: Deconstruction and Design Investigation
The simplest homemade bush shower is a bucket filled with water, with a hole (or holes) drilled at or on the base.
In this investigation, you will explore the problem of how to make the best bush shower. You will need to consider what factors impact user-experience when having a shower and how they might depend on variables relating to the design and set-up of a bush shower.
You will then design and conduct an experiment to determine the effect ofone factoron a variable related to the quality of a bush shower, by modelling and testing it in a controlled experiment.
ADeconstruct the problem (individual)
- Think about a range of factors that impact user-experience when having a shower.
- Brainstormvariablesrelated to the design or set-up of a bush shower which might impact the factors you identified.
- Considerpotential methodologies: how these could be tested in the laboratory and how the results could be measured and recorded.
- Think about theadvantages and disadvantages/limitationsof the different variables in relation to designing a valid and reliable experiment which could be carried out with the available materials and within the allocated time.
- Summarise your thinking.
BDesigning your own investigation (individual)
- Select one factor and develop and justify a method to investigate how that factor might influence one variable relating to the quality of a bush shower
- Your design needs to include
- Hypothesis
- Variables
- Independent
- Dependent
- Controlled (how and why they are controlled)
- Uncontrolled (and why not)
- Materials including quantities
- The procedure to be followed, including the type and amount of data to be collected
- A labelled diagram of the experimental set-up
- A blank data table to show how you will record data
- Identification of ethical and safety considerations (with level of risk, prevention and treatment)
Annotate your deconstruction and design to justify the decisions you have made about such things as the materials you have chosen, the independent and dependent variables, how and why you will control other variables, number of trials, measurements,
Evidence of deconstruction, the method/procedure chosen as most appropriate, and a justification of the plan of action must be a maximum of 4 sides of an A4 page. The minimum allowable font size is 10.
CImplementing an investigation (collaborative)
In defined groups, students (in consultation with the teacher) will negotiate an agreed upon method to implement and to collect data.
DWriting an individual report (individual)
You will use the data collected to write an individual report using the specifications from the subject outline as shown on the next page. This report is based on the investigation that was actually undertaken in Part C.
Maximum 1500 words or multimodal equivalent
Only the following sections of the report are included in the word count:
- introduction (including hypothesis and variables)
- analysis of results
- evaluation of method/procedure
- conclusion.
Deadlines
Check point 1: Draft of individual report due 3pm on the 19thApril 2024.
Final due date: TBC (1 week after receiving draft feedback.)

As specified on page 1 of task sheet. |
IAE1 |
Introduction |
Relevant Information presented that relates specifically to the practical being investigated. Includes the aim of the investigation, the hypothesis (which clearly links the independent and dependent variables) and the variables (independent, dependent, controlled (why and how) and factors that might not be able to be controlled (and why not) |
KA2/ IAE1 |
Safety |
Identifies the potential hazards associated with this experiment and determines the level of risk e.g. using a hazard risk matrix (see image below) Describes how the risk will be managed by considering both prevention (how will the likelihood of the hazard occurring be minimised) and treatment (what action will be taken if the hazard occurs) |
IAE1 |
Materials |
Lists all materials used in the experiment. |
IAE1 |
Method |
Detailed description of what was done in the experiment, including how the independent variable was changed and how the dependent variable was measured. Include a labelled diagram of the experimental set-up |
IAE1 |
Results |
Table has the correct format Data is represented in an appropriate manner- all data is shown Significant figures are correct |
IAE2 |
Analysis |
Graphs are drawn appropriately- axis are labelled, appropriate scale used, title, size, correct format. Appropriate variables are plotted on graphs as necessary, to determine the mathematical relationship between the independent and dependent variables. Trends are identified and are related to relevant physics concepts. |
IAE3 KA2 |
Evaluation |
Identifies evidence for, and causes of, uncertainty in the results including sources of: wrandom errors wsystematic errors wuncontrolled factors. Describes the effect of these errors on the data. Where applicable, describes how the procedure reduced the incidence and/or effect of these errors. Evaluates the reliability, accuracy, and validity of results, by discussing factors including: wsamplesize wprecision wresolution of equipment wrandom error wsystematic error wfactors that cannot be controlled. |
