### The Assignments

The students can choose from among the following assignments.  They can also choose in advance whether they can make an "A", "B", or "C".  If you are a teacher trying to use this for your class, substitute whatever assignments you wish.

#### Level C

Students can make a "C" by completing at least 12 of the following:

• Worksheet- The Elements
• Worksheet- Valence Electrons
• Study Guides to Chapter 9 (Glencoe)
• Concept Mapping: Chapter 9 (Glencoe)
• Worksheet: Who Am I?
• Worksheet: Element Code
• Activity: Valence Man cut and paste
• Lab: Arrangement of the Periodic Table
• Audio Activity: Chapter 9
• Alien Periodic Table
• Internet Activity: The History of the Elements
• Lecture: Metals and Non-metals
• Lecture: Arrangement of the Periodic Table/ The Structure of the Atom
• Demonstration: Flame test and metal salts

#### Level B

Students can receive a "B" on the unit by completing the "C" level and at least 2 of the following:

• Write a 1-2 paragraph essay on how the Valence Man activity compares to the periodic table.
• Observe 2 cans (1 aluminum, 1 steel) in the weather for 2 weeks.  Write your observations.
• Get a bottle of multi-vitamins and list the elements present. Use the periodic table to determine if each is a metal, non-metal, or metalloid. List in a table format.
• Make a table that lists metals used in world currencies. Find at least 3 countries.
• Write a letter to The Aluminum Association to find out about various uses of aluminum.
• Collect samples of easily attainable elements and prepare a board listing their names, properties, uses, with the sample of the element.
• Using Geometric shapes, create a model of a BuckyBall (Buckminsterfullerene).
• Create a 3-dimensional model of an atom.
• Find at least 5 web sites relating to chemistry that you actually find interesting.  Use the web site critique form to critique the sites.
• Write a 1-2 page double-spaced (12 point) report on one of the following topics:
• How/why silicon is used in the making of computer chips
• The Moh's Scale
• How the clearing of tropical rain forest affects the ozone layer
• A topic of your choice okay'd by the teacher

#### Level A

Students can receive an "A" by completing both the "C" and "B" levels and doing at least one of the following:

• Research and demonstrate an experiment that shows a chemical reaction taking place and be able to explain it.
• Create a multimedia presentation on the use of silicon in computer chips.
• Create a multimedia presentation on a topic okay'd by your teacher.
• Do a research paper on the history of coinage metals in the U.S.
• Lab: Preparing and Observing Oxygen (p. 286 Glencoe)
• Create your own web page that incorporates things learned in the unit. Your page should be a summary of sorts of "everything you know".  You can gear the page toward younger kids.
• Create a 20 question test with an answer key.

All grades are negotiable.  For example, you can substitute 2  "A"s for the "B" and "A" level stuff.

Each student must also keep a journal that reflects their daily experiences.  These will not be graded but will count toward your participation grade.
