  1. Description
    1. You must include a physical description. You can use your personal observations from photographs. If you cannot safely observe your molecule/substance, you must research.
      • Physical Characteristics (appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, etc.)
    2. Chemical description: You will need to research the chemical properties of your compound/molecule)
      • Chemical Characteristics (stability in air or other environment, flammability, volatility, etc)
  2. Discovery
    1. a. Describe the initial discovery of your molecule. Who discovered the molecule, when, how, etc? Some compounds are part of a larger substance/plant. If this is the case, describe the isolation of your specific compound. The isolation refers to the initial time your molecule/substance was discovered from its raw materials, or isolated from its natural resources. Please see here for some hints on the chemical isolation.
  3. Usage and Benefit or Harm to Society
    1. Where has your molecule/substance been used. Is it used regularly or is has it only been used on occasion? If your compound is one we ingest when eating, include information on foods it's commonly found in.
    2. Write about the Benefit or Harm to Society Caused by your molecule/substance. Many compounds can be used as bioweapons or have both positive and negative impacts. Other compounds have had benefits as medicines or have caused harm as illicit narcotics. All of these are good ideas to start out thinking about, so I'd like you to discuss these impacts on society, the future, and in any way you can think they may be beneficial or harmful.

Conclusions - ALL

  1. This section must contain:
    1. Four to six points that sum up the main topics of the presentation that you have in your outline

Reference Slide(s) and Internal Citations – ALL

  1. This section must contain:
    1. Internal citations - This is not just a separate section; rather, referencing should occur throughout the presentation via parenthetical citations anytime you paraphrase, make direct quotes, or use visual components from other sources. Please be sure to cite any language, images, videos, etc. in the presentation that should be cited.
    2. Reference Slide - Your presentation should also have a final reference slide listing 5-10 credible sources researched for your presentation. NOTE: these are not included in the slide count for your presentation.

Here are the notes that I wrote. I'm having trouble getting it to record, but I will be sure to get it taken care of before the due date.

Title: Hello, my name is Mark Austin and this is my presentation for the introduction to chemistry. I
chose to do my presentation on arsenic because it was one of the featured elements on the chemistry
world podcast. I had heard of arsenic before, but I didn’t know much about it. Doing this project has
made me more aware of its uses and applications, as well as it potential dangers.
Introduction: Arsenic has an atomic number of 33, meaning that it has 33 protons in its nucleus.
Arsenic has a molecular weight of 74.92 grams per mole, and the shorthand abbreviation is written as
capital A little S. Arsenic resides on the periodic table in group number 15. Some other elements found
in group 15 include nitrogen, phosphorus, antimony and bismuth. Arsenic is a classified as a metalloid,
meaning that it takes on some of the characteristics of both metals and solid nonmetals.
Properties: The stable isotope of arsenic is arsenic 75. Stable isotopes are ones that do not decay into
other elements. This form will have 42 neutrons in its nucleus. There have been a total of 33 i...
