This group project is designed to continue our study of chemistry while also incorporating collaborative work and learning. Together, our class will work to gain a deeper understanding of the organization of the periodic table and the trends and patterns that can be found within it. Using varoius technologies, such as this wikispace, our class will be able to communicate openly about the chemistry content while we learn it.

Please visit this site throughout our project and use it as a reference in our study of the periodic table and Chapter 5 of our text. Feel free to post discussion questions as they arise.

Below are important documents including: > > This document shows the grading rubrics for the PowerPoint, webpage, and Presentation > This document gives the overview and requirements of the project.
 * 1) An overview of the project
 * 2) Grading rubrics for the PowerPoint, the webpage, and the class presentation.
 * 3) An explanation of shielding using an analogy.

A worksheet comparing the shielding effect of electrons to an analogy of feeling the heat from a campfire. Your group must come up with your own analogy of shielding, draw a comic strip depicting it, and place the comic strip on your wikispace.
