PT project by 2K152b


									                      Hi! Welcome to your First Semester Final Assessment!
                              Dr Katz - Honors Chemistry – Greenhills School
Oh! How I love to spell words with element symbols (never mind that)! You will be working with your
NEW group to construct a three-dimensional periodic table (PT) complete with many of the components
you will need for the rest of the year. When you are done, you will have either summarized or pre-learned
everything there is to know about the periodic table! In addition, your group will then have a life-size PT at
arm’s reach!

You will be given a set of templates called foldables1 to assist you in this project. Each foldable template
comes pre-printed with element name, atomic symbol, atomic number, and average atomic mass (as shown
in the HI graphics above). They also provide a location inside the fold for you to write atomic number (this
is redundant, but these foldables were made by non-scientists), atomic weight (a.k.a. atomic mass - also
already listed, but on the front it is written without units, so you will write it again with the appropriate
units: g/mol), melting point, boiling point, properties (to be discussed below), and history. You can simply
indicate who discovered the element and when for the history of an element even though there are books
written about the history of some of elements; for some elements you will only find things like...“ ...has
been known since ancient times.” For other elements, especially the synthetic or radioactive elements, you
may uncover how they were synthesized in a laboratory.

There are numerous properties of elements; thus the small space provided isn’t large enough. As a result,
there is a need for the three–face INSIDE of the foldable! Here’s what the “matchbook” foldable looks like:

                     This is         When you cut                        The three-
                     where the       out the                             face panel
                     requested       template and                        INSIDE of
                     information     fold it into its                    the fold
                     is pre-         matchbook                           allows you
                     printed         shape it looks                      report lots
                                     like this                           of important
Here are some of the important properties you should collect about your elements:

   Electron configuration (ground state)                     Electronegativity (TRENDS)
    (TRENDS for main group elements)                          Ionization Energy (TRENDS)
   Atomic Radius (TRENDS)                                    Electron Affinity (TRENDS)
   Valence Electrons (TRENDS)                                Naturally occurring isotopes and percent
   Common Oxidation State(s) (TRENDS)                         abundances
   Color, texture in standard state                          Radioactive Isotopes
   Melting point (TRENDS)*                                   Classification (metal, non-metal, metalloid) –
   Boiling point (TRENDS)*                                    COLOR CODE YOUR TABLE
   Found in Nature (monoatomic, diatomic,                    “Group” Name – alkali metal, alkaline earth
    oxide, other?)                                             metal, transition metal, chalcogen, halogen,
   Allotropes (if applicable)                                 noble gas, lanthanide, actinide
   Common uses (there may be none for some                   Ionic Radius
    of the larger elements)

                      * already listed, but needed to be re-stated to point out TRENDS

You may notice that the word
TREND is found after many of the
properties listed above. Well the PT is
designed the way it is because of its
periodicity, i.e. because the properties
of the elements are similar to
elements near them on the PT and
they occur in trends (patterns).
Scientists can predict chemical
behavior based upon the location of
an element on the PT alone!

Since these properties tell us so much
about an element, it will be pretty
important for us to understand and
be able to identify these trends, so
your tables will need to have a key or
legend which will define and identify
any property that is periodic on the
table. We will use a different version
of the matchbook foldable to report
these (see diagram to the right).

So, what’s the goal of this project?
Your job is to research all of the
elements, collect data for the
properties listed and more, and
display them in some amazingly
creative fashion on a large tri-fold poster board. First you must brainstorm as a group to determine how
you will want to creatively display the PT. Then you will have to delegate jobs, and elements, among you.
You have a deadline to meet (Dec 12th ) for which you are all responsible; I strongly recommend that you
make some “due dates” for yourselves to report in to each other to see if one person “needs a hand” with
his or her part. Teamwork is about sharing the burden of producing a product, not placing blame when one
person is unable to perform a task, so each person needs to be clear about his or her own ability to
contribute. Part of this project is about learning to collaborate. We will design a rubric as a class so there
will be complete communication between us about what is expected of you.                (see next page)
I have sized the foldable templates so that the element squares will just fit on a tri-fold board. This will be
the most convenient way to display your tables, plus we will be able to easily store them in class for when
you need to use them. Additionally, you will be able to glue your key or legend (which will consist of your
definition/trend foldables and your color schemes key) on the OUTSIDE of the folded tri board. While
this isn’t ideal, it does work. If we figure out a way to hang your PT on the wall, we will simply hang it by
the center panel and it will still be foldable on the wall. See below for how I envision this working3.

                             affix to wall at arrow

Inside is where                                                                                Outside is where
you’ll glue the                                                                                you’ll glue the
element foldables                                                                              definition/trend
with all of the data                                                                           foldables

foldable for each
individual element
in the PT shape                                                                                You can put
                                                                                               other stuff here
                             affix to wall at arrows

We will either store the projects folded as shown in the picture on the right (above) on their backs, or we
will affix them to the wall at the corner locations of the center panel, as designated by the block arrows in
the picture on the left above. In other words, don’t use the back of the center panel for a location to put
information. You also do not need to decorate the back of the center panel. You may place your group
name there if you wish; however, you might want to proudly display your names upon the front of your
beautiful table. Either location is acceptable.

I have listed a few websites (in the endnotes) to get you started, but there are limitless resources for you to
retrieve information about element properties and periodic trends. Don’t forget to keep a list of URLs that
you visit so you can properly cite your references in a “works cited” type of bibliography. MLA format can
be found easily online4. You will need to put your works cited on a visible location on your PT.

This grade will count as 20% of your Semester 1 grade. Since it is a group project, it would be
understandable if you feel uneasy about relying on other students for the outcome of 20% of your grade.
Therefore, you will not be forced to participate in this project, and may instead opt to take a cumulative
Semester Exam. However, should you decide to opt out of the Project, you are still responsible for learning
the same material that goes into this project; therefore, the material that your classmates are researching for
their PT project will show up on your Exam. You will be expected to know it only at a basic level, not at an
applied level. You will be expected to know the periodic trends and their definitions; you will be expected to
know the names and symbols of the elements, and you will be asked the names of the groups on the
periodic table. You will be expected to know how to identify metals, non-metals, and metalloids. You will be
expected to know which elements on the periodic table are solids, liquids and gases, and which occur in
nature as diatomic molecules. Additionally, you will be expected to know the common oxidation states of
the main group elements and the number of valence electrons the main group elements have. All of this
information has been covered this semester and can be obtained from PowerPoints, screencasts, and the
textbook, just like any other material information could be obtained. If you decide to take an exam instead
of participate in the project, you will not be required to know melting points or boiling points of any one
element but you will be expected to know the trends. You will not be expected to know common uses of
elements or the allotropes of each element. I will provide a study guide for those of you who select this
option well before finals week and I will give you practice problems as well.

Designing a rubric together as a class is no easy task. It is difficult enough to create a good rubric with one
brain, but with all of us working together it will be much harder. However, I’d like you to have some
ownership of the process. I thought perhaps if I provide a template, we might have an easier time. So, based
upon the assignment described above, I listed the minimum graded topics I’d like to see in the rubric:
