Your grade will come from your ability to demonstrate your skills by accurately performing scientific techniques and your scientific writing ability. You will need to select the appropriate equipment, solve chemical problems, collect and assess information. As this is a laboratory report, it should be written in third person narrative and all scientific terms used should be defined. Someone who has not carried out this practical before should be able to replicate your method exactly. Learning Outcomes By completing this assessment, you will: Key and Employability Skills Task Demonstrate analytical skills in collecting and assessing information and solve chemical problems. Use basic techniques in laboratory practical work and develop an awareness of risks involved in the laboratory environment, work safely in the lab and use appropriate equipment. To accurately conduct a practical task by completing a risk assessment, choosing the appropriate equipment collecting and assessing information, as well as communicating your findings in a scientific laboratory report. You must complete the following practical for your laboratory report: Determine the concentration of aspirin in the powder sample. Instructions You should: Conduct your own research and cite all your sources appropriately using the Harvard referencing style. Demonstrate your analytical skills in collecting and assessing information and solve chemical problems. Use basic techniques and appropriate equipment in your laboratory practical work and develop an awareness of risks involved in the physical laboratory environment. Write in the third person narrative and all scientific terms used should be defined. о Someone who has not carried out this practical before should be able to replicate your method exactly. 2 Cardiff University International Study Centre 23/24 CARDIFF UNIVERSITY PRIFYSGOL CAERDYD Study Group Sections to include: Your laboratory report must be structured in this order; however, you may begin writing the sections in any order. 1. Title of your practical investigation 2. Abstract 2.1. Precise summary of the whole report Consider writing the abstract after completing the rest of your lab report 3. Introduction 3.1. Brief overview of key theories related to your practical investigation 3.2. Review of literature based on similar practical investigations 3.3. Objective (aim) of this practical 4. Method 4.1. Risk assessment What hazards/risks do you have to consider when conducting this practical? How did you reduce the risk of the hazards occurring? 4.2. Equipment and other material (such as chemicals including volumes and concentrations required with units) 4.3. Method 4.3.1. Conducting the titration using the standard solution to determine the concentration of the aspirin. This must be detailed and clear. Another person must be able to follow your method exactly. 5. Results & Calculations 5.1. Results described in a paragraph. 5.2. Any observations made during the practical (such as colour changes) and in the results (such as trends) 5.3. Results presented in a table with a short descriptive legend. 5.4. Processed data with step-by-step calculations 6. Discussion 6.1. What do the results mean? Compare trends in primary results to other investigations. 6.2. Do they answer the questions of the practical investigation? 6.3. What errors were introduced when you conducted this practical in real life? 6.4. Would you make any changes to how the practical was conducted? If yes, what would they be? If no, why not? 6.5. Any potential impact of your results on real world application? 7. Conclusion 7.1. Short review summarizing your main results, and significant findings. 8. References 8.1. Harvard Referencing only 9.
