Chemistry

What is the difference between “natural” and “non-natural” medicine, supplements, or products? Based on what we’re learning this semester, how rigorous is that distinction? Especially in our consumer age when the “organic” label comes with commercial overtones, it’s important to think about what’s behind the label. Using examples, and incorporating information from class, answer one of the following questions: Make an argument for or against the use of “natural” or “organic” products in a particular area of life (e.g. health, medicine, cleaning, clothing, etc.) Make an argument for how to define a product as being “natural” or “organic”. Content: You should be sure to address the concepts necessary for understanding the explanation to your answer, explain the concepts, layout your answer to the question, and illustrate your answer with informative examples (plural). You may draw your examples from any field of chemistry or medicine you like, and it is recommended that you use this project to highlight the relevance of chemistry to your chosen field of study and/or professional discipline of interest. Format: You should prepare a multimedia presentation (be creative!) to explain the ideas in your presentation (PowerPoint, video, skit, song, etc).

Description: Essay 1000 words Causes of chemical pollution and their effect on our natural resources also reference it

1) Title including the name of the element (on a title page) 2) Discuss important properties of the element including at least three compounds in which the element appears 3) Discuss biological, biomedical, and/or commercial applications of the element. 4) Discuss other interesting facts about the element. 5)The report should include four sources cited within the paper and on a reference page

Assignment 1: The Annotated BibliographyObjective: Assess sources for your research for your final presentation (for credibility, reliability, and relevance) and list references in proper APA formatAssignment Instructions: The Research Project/Presentation for this class is divided into three major Assignments, 1) annotated bibliography, 2) outline and 3) final presentation. The first part is the annotated bibliography. An annotation is a summary and evaluation, and your annotated bibliography will include a summary and evaluation of some of the sources (or references) you will use for your presentation.To prepare for this assignment, I recommend that you do the following:Read these directions carefully.Review the sample annotated bibliography provided to you below.Message me using Classroom Support with any questions!The reason the annotated bibliography is included as part of the research project is that writing an annotated bibliography is important in that it provides excellent preparation for the final presentation. One of the issues regarding any type of research, especially in chemistry, is the credibility of the sources used, particularly those obtained from various websites. By forcing you to evaluate each of your potential sources carefully, the annotated bibliography helps you determine if in fact the source you chose is credible and helps you determine how relevant it is to your topic and understand the topic better which will help you develop your presentation.For this project, you will assess three sources to include:1) a complete citation for each source,2) a summary of each source, an3) an evaluation of each source.Three sources are required for this assignment (i.e., you are to write an annotation for each source). However, you must use five or more sources in your final presentation.

Choose the topic for your course project.Familiarize yourself with PowerPoint with Audio Narration, which you will be using for your final presentation.Upload a “mini-presentation” introducing the molecule of your choice and explaining why you chose this topic for the course project.
