The purpose of this experiment was to explore the principles of investigating a crime scene; utilizing both biological and chemical laboratory techniques. Collecting proper evidence is crucial to crime scene investigation. The insight that an investigator may gain about a perpetrator can be determined by analyzing the physical evidence obtained at the scene, and therefore an investigator must carefully examine numerous pieces of evidence found at a crime scene. However, the knowledge and education of the investigator are able to elucidate both the obvious and the obscure. Each piece of evidence may provide a clue to who committed the crime that is under investigation. Techniques such as hair, gunshot, fingerprint, footprint and blood spatter analyses were learnt and then used in the investigation process. This research project involved the investigation of a hypothetical crime scene, which was analyzed by using the aforementioned forensic techniques.

Natural products of fruits and vegetables play important roles in human health. Due to their benefits, researchers have tried to identify specific natural compounds within a single fruit or vegetable. These are technically demanding experiments because of the complex sample matrix and the need for a sensitive chemical analysis technique. This research project presents optimized protocols for the organic extraction and separation of multiple natural products of fruits and vegetables. The compounds were analyzed, and characterized by using Gas Chromatography-Mass Spectrometry and cross referenced with journal articles that have previously reported these products.
