Welcome
Chemistry Teachers
Pearson Prentice Hall:
Teaching for the Regents
Why Use Graphic Organizers?
New information becomes visible and
colorful
 Can be used as guided notes
 Help students to become organized
 Can be used as a study guide for a
chapter test and Regents

- What are the main topics in this chapter?
- What formulas are needed?
- What vocabulary is needed for this unit of study?
- Will you need a graph?
- Where can you use calculators?
*** Use the guided notes handout with a practice Regents test
and highlight only problems that use this organizer in the
same color as the guided notes handout. ***
