Everyday Chemistry Project

 Chemistry  

Due Dates    Monday, January 4, 2009   (for bonus points) Thursday, January 7, 2009 (Final Required Due Date)       

     Part A:  Choose 2 EVERYDAY CHEMICAL APPLICATIONs (may choose from the list of topics
 provided.)  Topic selections are based on a lottery. You are encouraged to focus on the practical
applications of basic chemical principles. You are to highlight one example from each of the 5 major
types of reactions:  You may also use redox reactions (a type of single replacement) and acid base
neutralizations ( at type of double displacement reactions) The history and background information
should be kept to a minimum.  This is a chemistry research activity and information is graded on any
and all chemical relevance (such as any topic we have covered in your chemistry book). One of your
topics has to be presented in the form of a crib sheet.  Click on  the menu bar above: How to make a crib
sheet for instructions.   Be sure to include diagrams that explain your topic. Notice the giant examples
of cribsheets in my room.  They have a focus point picture with other diagrams and pics highlighting
 concepts pertaining to the important topic.  This must be printed in color and sent to Ms.
Riddle as an attachment to the following e-mail: riddler.dhc@pitt.k12.nc.us.
 These may be used again in the oral presentation, but not limited to those. For Example:  If you choose
 Chemistry in Electronics, you must focus on principles we have covered such as the cathode ray tube,
 red, blue, and green wavelengths of color, transmission of radio and TV waves, red, green, or blue
phosphors, etc.  You are to complete another type of graphic representations of your 2nd and third
research topics "One should be a poster. If you do three, it should be a powerpoint: 5 slides maximum or
a 3 dimensional model, video or computer generated presentations like moviemaker or your own
website, etc.
Part B:  Elements
Choose one or more elements that relate directly to your EVERYDAY CHEMICAL APPLICATION .
Research these and include the following: A) all historical background  B) General properties and
grouping according to any information derived from the periodic table  C)  The element(s) uses,
hazards, toxicities, etc.D) Where and how this element is obtained ( naturally, man-made, etc.) 
 Part C:  Highlight a SCIENTIST
that is instrumental and relevant to your EVERYDAY CHEMICAL APPLICATION TOPIC.  Biographical
information should be limited and the focus of this part is based on the scientific contributions of your
scientist, especially toward the focus of your research.  This is to be included as part of your crib sheet.
 Part D:  Expert in the field/personal contact
You should contact and interview an expert in the field of chemistry that your
topic focuses upon.  The interview can be electronic: e-mail, telephone, fax, etc.  but, it has to be
recorded as a hard copy .  You must also include your expert's qualifications and expertise in the field
of study.  For example, if your topic is the chemistry of color photography, a technician in one of the
one-hour photo labs is not a good choice.  However, a chemist that works with Kodak may be available
over the internet.   It is critical that you do this as soon as possible---no credit for letters being UPS
overnighted that never show up.  Once again, the focus is on the principles of chemistry involved , not
how many children and dogs the chemist may have.  Yes, you may use a parent, aunt or cousin if the
person is qualified!!!! 
Part E:         Make a cover page with the following information:
The title of the Report
by
Your name
Class/Period
For
R. S. Riddle
Honors Chemistry
The Date 
    If you do not have access to a word processor or computer, see the teacher about hand-written
reports.       Include a bibliography with a minimum of the following 5 different resources: 1 reference
book: Encyclopedia 1 CRC Handbook of Chemistry and PhysicsPeriodical such as the Journal of
 Chemical Education by ACSA website referenceOther books  5)      Documentation of the bibliographical
references will be referred to the MLA  Handbook for Writers of Research Papers.  The teacher has a
copy as does the Media Center.  6)      1 day of  class time for computer-based research on the
WWW/internet. Make sure your password and logins are
current and useable.  Times and dates TBA.  7)      This will count as a major test grade for the third nine
 weeks, possibly two.  Begin work as soon as possible, especially your expert in the field contact.  Choose
your topic carefully---information that is hard to find does not make for a good topic.  No consideration
is given for not finding enough information.  8)      Be sure to ask questions---do not assume anything.

 

 

Special Note: I will put up a checklist and table formatted rubric ASAIC (As soon as I can)

Honors Chemistry:  Scavenger Hunt

 

Ions:   Cations, Anions, and Polyatomic Ions

 Objective:  To familiarize you with ions and all the possible combinations of ions to make chemical compounds. Background Information:  Ions are a special group of atoms that have either gained electrons or lost electrons.  When this happens, the atom is no longer neutral in its charge.  CATIONS are the metals that lose electrons easily and ANIONS are the non-metals that gain the electrons usually lost by a cation. Polyatomic ions have 2 or more atoms combined as a unit and have an overall charge.  Examples of these cations, anions, and polyatomic ions were given to you in the hand-out entitled:  Formulas and Charges of Ions. Ions have rules for the way we name them:   Metal cations have names the same as the element:  Na is the symbol for the atom named sodium.  Na+ is the symbol for the cation sodium that has lost one valence electron. Non-metal anions with a negative charge have the names changed to “ide” endings.  For example :  F- is the symbol for the fluoride ion that came from the fluorine atom that had gained one electron. Most polyatomic ions end in either “ate” or  “ite” depending on how many oxygen atoms are in the ion. 

Procedure/Requirements: 

A.    Collect labels, boxtops, make copies, etc. of everyday household items that have ions listed as part of the ingredients.  For Example:  on the Vienna Sausage Label shown in class:  sodium nitrite was found

B.     Staple, glue, etc. the label or copy of the label to one sheet of paper and write the name of the compound along with its formula.  Label the ions also. 

C.     The same label can only be used to demonstrate at the most 2 ions:  The above label will show  the Na+ ion and the NO 3 – ion on the same page. You cannot use the same brand/label for any other compound for more than 2 compounds.

D.    You should include a paragraph summary or develop a chart to tell  about the compound’s chemical and physical properties along with any other interesting information.

E.     You will need an inexpensive duo-tang folder (with metal clasps) or a 1 inch 3 ring notebook to secure all your pages. Do not use the plastic sheet holders! (Dividers with tabs are acceptable.  Some people have taken it to get it bound in the past)

F.      Creativity, neatness, and thoroughness are all important.  Extra effort means extra points as usual.

G.    Examples from all categories must be displayed.  A total of 15 cations and 15 anions will give you an AVERAGE GRADE of C.  It will take extra effort to make above average grades of B or A.  Extra labels, descriptions, paragraph summaries will help you make an A. Project is due on Tuesday, November 24 or before.  If there is any question you may be absent from school that day----turn your project in prior to  November 24th or send it with someone else. 

H.    Include a coversheet and bibliography. Number all pages and put a table of contents in your notebook.   I

.       Please organize your notebook of ions in some logical manner. 

J.       EXTRA,EXTRA,EXTRA goes a long way: Creativity, thoroughness, added information, organization, neatness, organization, etc. etc.  The more the better, but limit to no more than 25 Labels, because you will not get any more bonus points. 

K.    I will do a rough draft check by next Friday, the 13th for a lab grade. You should have at least 7 compounds completed and ready to be checked, a title page, a bibliography started, a table of contents.  Be sure to have your checklist as the very last page.
