| To carry out the experiment, please refer to the instructions for your specific practical assignment which can be found in a separate document. Your tutor will advise which experiment you will be carrying out in order to complete this assignment.
Completing the lab report
1. Introduction and aim
The introduction should include a clear and detailed aim of the experiment with supporting background research to explain the theory and idea behind the experiment. It should also explain how the results you collect and analyse will enable the aim to be achieved and how the equations relate to the experiment and graph.
2. Apparatus and diagram
You must include a full list of all apparatus and equipment used during the experiment, including quantities, which is supported by a clear and fully annotated scientific diagram. You should also explain the choice of suitable materials and measurement strategies that enable you to produce accurate and precise results.
3. Variables
You must identify and explain the dependent and independent variables within the experiment, including units, values and range. You should also note at least two controlled variables within the experiment, explain how they are controlled and the consequences that will occur if they are not controlled.
4. Method
The procedure must be a detailed and clearly explained step by step method of the experiment with methodical and sequential instructions including range and repeats. You should discuss the suitability of the procedure in relation to the aim of the investigation.
5. Safety
You must identify all hazards related to the experiment and assess the risks associated with these hazards. You should describe and justify the appropriate safety precautions that must be carried out to ensure the experiment is conducted safely in a laboratory environment, including the consequences should this safety issue occur.
6. Results table
Your results must be recorded accurately in a suitable table, with correct headings, units and rounding. The results should be presented clearly and must be fully reliable, including required calculations.
7. Results graph
Your graph must be hand drawn with an appropriate linear scale, units, title and labelled axes. The graph must also be a suitable scale based on the size of your paper. Your results must be accurately plotted on the graph, including a line/curve of best fit and intercept identified (if appropriate).
8. Gradient calculation
You must accurately calculate the gradient of your line of best fit, including correct units. You should explain the relationship between the gradient and the quantity to be determined from your original aim. This may also include reference to the intercept if appropriate.
9. Critical analysis of results – conclusion
This section must include a conclusion based on the stated aim of the experiment and contain a detailed analysis of the results, identifying and describing clear trends and patterns with reference to your results data and graph. You should ensure scientific terminology is used to critically analyse the results, which includes suggestions of any further calculations or experimentation that may be required.
10. Evaluation of scientific investigation
You must provide a scientific critique of the experimental design and procedure of your experiment, identifying at least two areas of improvement. Anomalies should be identified, and explanations given into possible sources of errors and uncertainties. This should also include the consequences of potential/identified anomalies and how this affects the processing of data, looking at future experiments of this nature.
11. Referencing
Throughout the laboratory report, you should have carried out a range of research to support your understanding of the aim of the experiment. In this section, you must provide a complete list of research sources correctly cited in Harvard Referencing style, including the date you accessed the source.
