IGCSE Coursework Assessment Criteria •
The best two results of C1 to C4 will be your score.
Units are only written in table headings eg. Height (± 0.05cm) Data taken with correct significant figures eg. 10.55, 10.50, 10.00

Your Name TITLE OF PRACTICAL The title must be specific and include the dependent and independent variables. For example, ‘An Investigation of the Concentration of Vitamin C in Different Brands of Orange Juice’ NOT: ‘An Investigation into the Amount of Vitamin C in Orange Juice’. Don’t use the word amount in the report – it is too vague. Make sure your complete report is easy to read with all the clear headings. Don’t add unnecessary information. Have everything formatted well. You are writing a piece of functional English using scientific terminology that would be understandable to your peers. Introduction This needs to give the marker a quick understanding of what you are doing or any other relevant background information. Include chemical reactions, or scientific theories and models. Aim What you are trying to achieve. Prediction Predict what the outcome of the investigation should be based on scientific models or theories. Variables Independent Variable:
Dependent Variable:

Your Name Equipment List your equipment including ranges and uncertainties eg. Measuring cylinder 0.0-100.0 ± 0.5cm3 The equipment and method will repeat some aspects of your variables section. Method Include a diagram and number the steps. Label the diagram: ‘Figure 1: Experimental set up’. Results Table with units in the headings eg. Temperature (± 0.5⁰C). Label the table: ‘Table 1: …’ eg. ‘Table 1: Temperature data for varying amounts of acid’. This is so you can refer to it in your paragraphs. Make sure you have correct significant figures eg. For the above temperature heading, 0.0 not 0. Also if the uncertainty is 0.5, you can only have readings of .0 or.5, not .1, .2 etc.. Make the first column the independent variable, and the first row the dependent variable. Analysis: Graph with units and headings. Label the graph: ‘Graph 1:…’ etc similarly to explanation above. Make your graphs and tables as easy to read as possible. Have it big enough to clearly see detailed grid lines, marked points and line of best fit with equation. Continuous data is a scatter graph, discontinuous data is a bar graph. Have one example calculation to represent all the data analysis you have done. Clearly write the equation, substitute, and give final answer all with units. Start by writing something like, ‘This is the example calculation for the first reading...’ Discussion In the first paragraph, explain the relationship of the graph. Be sure to distinguish between line and curved relationships etc. Explain the result using scientific models and theories from the syllabus. In a separate paragraph, explain anomalous results (eg. are not exactly on the line of best fit if line graph). Explain why a particular data point is not perfect. Be specific and use units when talking about data values. Talk about any systemic or random error and whether to accept or reject these points. Write separate paragraphs for separate ideas. Evaluation This is to judge your method – what was inaccurate and how to improve it (create better ways to do it). Each paragraph is to: 1. List an error in the method used 2. Explain the error scientifically and how it would have affected the results – higher, lower values? 3. Specifically show what changes can be made to the method to decrease this error Last paragraph include a further investigation that would help you better understand this investigation. Don’t confuse split up or mix up your paragraphs. Use what you have learnt in English about functional writing and clear paragraph structure.

Your Name Conclusion State if you hypothesis was correct or not, with a generalization or pattern that was discovered. References Use an accepted format (use www.easybib.com). Try not to have pictures from another source or you have to reference it. Reference all your research. eg. Higdon, Jane. "Vitamin C." Linus Pauling Institute at Oregon State University. Oregon State University, 17 Oct. 2008. Web. 14 Oct. 2009. . Number these, 1., 2. etc. FINALLY: Proof read your report – any punctuation or spelling mistakes? Is everything formatted the same and looks easy to read? Does the report flow easily? Is there any unnecessary information or parts that need deleting? Do all the sentences make sense? Give your report to a peer to see if they have any trouble understanding any of it.
