Primary Discussion Response is due by Wednesday (11:59:59pm Central), Peer Responses are due by Sunday (11:59:59pm Central).

Chemicals of Concern in the Environment

As scientists and engineers work to produce products that make people's lives easier and safer, there is the possibility that these new products could have negative consequences on individuals and the environment. In this lab, you will select 1 of the chemicals listed below and learn about its role in improving lives, as well as the potential unintended consequences it may have.

Chemicals of concern (select only 1 to research):

  • Brominated flame retardants are added to plastics and fabrics to make them more flame-resistant. This chemical is regulated by the U.S. Environmental Protection Agency (EPA).
  • Cadmium is an element known as a heavy metal. It is used in batteries, paints, and plastics. It is regulated by the U.S. EPA.
  • Phthalates are chemicals added to plastics to make them more flexible and are regulated by the U.S. Food and Drug Administration (FDA).
  • Bisphenol-A (BPA) is a chemical that is added to plastics to harden them, while keeping them light. It is regulated by the U.S. FDA.

Primary Task Response: Within the Discussion Board area, write 300–500 words that respond to the following questions with your research. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas.

  • What role does your chemical play in the modern world?
  • What are some possible detrimental health effects that are associated with the chemical you selected?
  • Explain the position of the U.S. FDA or EPA regarding your selected chemical. In the above list, you will see which of these two agencies regulates your selected chemical.
  • What is the position of your state government regarding your selected chemical?
  • Do you feel that your chemical should be more tightly regulated in the United States? Why or why not?
    • Would label requirements be enough?

Computers are part of people's everyday lives. You are likely reading this assignment on a computer screen right now; you may have a smartphone sitting on your desk, and maybe you just came back from a business trip during which you made airline and hotel reservations online. Over the last several years, you may have noticed that computers are able to store more information and process that information more quickly. New research into the electron spin of atoms hints at a new computer revolution in the near future.

Assignment

For this project, you will be exploring the developments in material science that have allowed computers to become so fast. To do so, please address the following in 3–4 pages (not including the Title and Reference pages):

  • What are the 3 essential properties of every material?
  • New materials often lead to new technologies that change society. Describe how silicon-based semiconductors revolutionized computing.
  • What are microchips? How are they related to integrated circuits?
  • One of the pressing questions about the increasing ability of computers to quickly process large amounts of information is whether a computer can be built that is considered "alive" or "conscious." What is artificial intelligence?
    • What are 2 essential differences between human brains and the central processing unit of a computer?
