Discussions in this course are set up deepen your understanding of the material
as you make real world connections and employ creative thinking. To get the
most from these discussions, full engagement is expected on the part of the
student. Be sure to stop by the discussion section frequently, not only to
post, but to read the postings of your peers and instructor. Engaging with your
peers and learning together is key to this experience. For you initial post, choose
one of the options below:
Option 1:
We will
begin this topic by practicing the use of the scientific method. The steps of
the scientific method are: observation, hypothesis, experiment, results, and
theory. Using your understanding of the scientific method from your readings
and lessons, you will be applying this knowledge to a real world situation.
Take a real world scenario in the news, or another outside source and apply the
scientific method, being sure to detail the controls on your experiment. ?Describe
a result that would confirm your hypothesis.
Option 2:
Choose a
scientific paper written in the last year.
The Chamberlain library is a great source for this. For your chosen paper, look into the study
and discuss how the scientific method was used in this paper. Be sure to note they hypothesis, variables,
results, etc. Based on your
understanding of the scientific method, be sure to discuss if you find this
paper as a trustworthy source and why.

Option 1:
Your
initial post in the discussion this week consists of two parts. First, choose a
molecule used in healthcare, industry, or found in a natural source and discuss
the importance of this molecule. Be sure to include at least one outside source
and make sure to follow APA citation guidelines.
In the
second part of your initial post, we will be practicing naming ionic and
covalent compounds as well as polyatomic ions. To begin, give the chemical
formula for each of the following: A covalent compound containing no more than
two types of elements, an ionic compound no more than two types of elements,
and an ionic compound containing a polyatomic. Be sure that these compounds are
valid (for example, the charges balance out in the ionic compound) and that the
subscripts do not exceed 10.

The
electron configuration of an atom determines the number of electrons available
to participate in bonding with another atom. One method of depicting the
valence electrons that an atom has is through the Lewis structure. For the
second part of your initial post, pick an element from the periodic table of
elements. Identify the valence electrons and the orbitals in which they reside.
