It highlights the development of practical laboratory skills, independence, and confidence in conducting experiments, as well as an understanding of how these techniques interconnect with broader scientific principles. The work demonstrates strong practical competence and reflective insight, clearly showing ...

This assignment explores the principles and applications of chromatography, focusing on the separation of amino acids using both paper and thin-layer chromatography (TLC). It provides a clear and detailed explanation of how intermolecular forces, solvent polarity, and other factors influence the separation process. The work demonstrates strong scientific understanding, linking theory to practical application while explaining the role of Rf values in identifying different amino acids. The assi...

Unit 4: Laboratory techniques and their application. Distinction Assignment. I hope these assignments are helpful to you all !

In this assessment I had to determine the concentration of an unidentified sodium hydroxide (NaOH) sample for this evaluation. In order to do this, I had to titrate the hydrochloric acid (HCl) against a standard sodium carbonate solution (Na2CO3) in order to figure out its concentration. I did this assignment in double applied science BTEC and I got a distinction, I hope this helps you all :))

Introduction: This experiment was designed to investigate the link between temperature changes and physical changes in cooling curves using paraffin wax and stearic acid as examples. A cooling curve is a graph that shows how something cools over time. To do this, I had to use different techniques with a tool called a calorimeter to learn about the curves better. Calorimetry is a method scientists use to measure heat during reactions or changes. They use a device called a calorimeter to do this....

coursework on the applied science level 3 Unit 2 A on titrations. I got a distinction for this

This is my Assignments C and D for Unit 17 of the BTEC Level 3 Applied Science course, focusing on microbiology and microbiological techniques. In this work, I carried out aseptic techniques to culture microorganisms and explored factors controlling microbial growth in industrial, medical, and domestic applications. I was really proud to achieve a Distinction for this work, and I hope it can help guide you too! Just a little reminder — please use this as a reference only and don’t copy it di...
