"Curriki is more than your average website; we're a community of educators, learners and committed education experts who are working together to create quality materials that will benefit teachers and students around the world." From About Curriki

The Curriki Open Source Chemistry Text primarily covers the content standards of the California Chemistry Standards. Occassionally, some additional topics are covered to transition from one topic to another, but some content traditionally included in a chemistry textbook has been removed. Furthermore, the textbook is a content reference and not a reference for labs, worksheets, tests, or other supplementary material—many of which are available in each folder.

All tested and starred California Chemistry Standards were used as an outline for this text and, for the most part, the topics are presented in the order of the published standards. Sometime, particularly the unit of nuclear chemistry, some starred standard needed to be introduced earlier than the tested standards and the order of materials is adjusted to make a coherent presentation of material. Please visit the CA Chemistry Standards to see the specific content covered within this digital collection.

This text is only a beginning to the resources that are available at Curriki. Inside each folder are other resources such as labs, worksheets, and slide presentations. The goal of Curriki is to use the strength of the online education community to build a collection of supplementary material that will support the text in ways that are innovative, comprehensive, and meet the needs of California teachers. We encourage you to be a contributor of resources, to be an editor to tease out the incorrect, incomplete, and confusing passages from the text and the resources, and to develop lesson plans that provide teachers with the tools to make efficient and effective use of the resources.
