Purdue Global Forensic Evidence Collection Paper
The Importance of Forensic EvidenceOne of the most powerful parts of a case against a criminal can be the forensic evidence that is collected and presented. Dramatic breakthroughs in both the scientific and technological fields have greatly impacted the criminal justice system.Imagine that a recent crime wave has swept your city. You came home last night to find that your home had been burglarized. Understandably, the police and crime lab are overworked and in need of help. Physical evidence (meaning any materials at the scene of the crime that could be valuable to a criminal case) was collected by crime scene technicians at your residence and from a possible getaway car. Review the evidence that was collected from the crime scene. You will need to complete the Assignment template provided after considering the following information:Choose three pieces of evidence that were collected from the crime scene to examine in detail.Define the physical properties of the evidence collected. Also include any biological, chemical, or other characteristics of the data that would be important to the investigation.Explain what specific tests would be performed on the evidence and what information can be extrapolated from this evidenceHypothesize how the evidence could be used in the investigation and at a trial. Note that although this is largely a hypothetical investigation, the description of a material and how it is tested will be factual and you will need to conduct research using the PG Library to identify reliable sources. The final results and importance of the evidence in an investigation will be up to your interpretation and will be largely hypothetical.Review the links below for additional information.National Forensic Science Technology Center.

Yes or no. 2. Suppose that you were given a sample that had a pH of 6.5 but you were unaware of the pH. a. Can you perceive a problem that would arise if you attempted to determine the pH of this sample using either anthocyanins or pH paper? b. What about using a pH meter? 3. a. Is the use of anthocyanins qualitative or quantitative? b. is the use of a pH meter qualitative or quantitative? 4. Which measurement would you consider to be a most reliable measurement; anthocyanins, pH paper or pH meter? End of Lab J

Rate of Photosynthesis Data Analysis
For many metabolic processes, like photosynthesis, it is often difficult to make meaningful observations without expensive laboratory equipment. You can look at a green plant and assume that photosynthesis is occurring, but there are few ways for you to observe the chemical reactions involved in this critical metabolic process.
On land, the gases involved in photosynthesis, carbon dioxide and oxygen, would be exchanged by the plant without any notable indication. However, in certain aquatic plants the situation is slightly different.
The waterweed, Elodea, undergoes photosynthesis while completely submerged in water. The oxygen that is produced by the plant is released as tiny bubbles. As a result, you can get a relative measure of the rate of photosynthesis by counting the release of gas bubbles.
In this assignment, you will investigate the relative rate of photosynthesis by quantifying the gas bubbles emitted by the waterweed, Elodea canadensis.
Instructions
This assignment focuses on the graphical presentation of the data, your analysis, and a discussion to report your findings.
Complete the interactive activities embedded within the page prior to analyzing the data. These activities are designed to help you understand the scientific method and how it applies to this specific mock experiment.
Graph the data in the appropriate format. Make sure that you present the data in the format that best demonstrates the results.
Analyze the data, looking for trends and evidence that supports (or disputes) the hypothesis.
Prepare your discussion that focuses on the back ground science, the results, any relevant scientific concepts that can help explain the results, and further tests or new experiments to expand on what was learned in this experiment.
Note
Science is always best when you have an opportunity to participate in the process, from planning the experiment, setting up the equipment, to collecting and analyzing the data. As the majority of students will not have access to the required equipment or materials, this assignment is designed to allow you an opportunity to analyze the data and make required connections to the course content.
