CEF provides study materials to help students succeed at every level of the Challenge and expose them to the fascinating world of chemistry as it applies to everyday life. The Passport to Science Exploration is divided into three sections that correspond to the different levels of the Challenge: local, state, and national.

To prepare for a Challenge competition, students should carefully National Challenge 2015 - Audreyread and review the information in the Challenge study materials. Competition questions are based on an overall understanding of chemistry and science concepts presented in these study materials, as well as the relationships among concepts. Questions are largely derived from information contained in CEF’s study materials but are not restricted to this information.

We encourage students to seek additional examples and explanations of chemistry concepts from outside resources. CEF does not provided any suggestions or recommendations for any participants regarding outside resources. Doing so will help students to answer questions that require them to connect concepts, apply their knowledge of chemistry to familiar and unfamiliar situations, and learn more about the world around them!


Study Materials for the Qualifying Exam and Local Challenges


Study Materials for State Challenges


Study Materials for the National Challenge

Please note: Participants that will be attending the 2015 National Challenge will receive a copy of these study materials by mail.
In addition to the reviewing the study materials below, students should continue to review The Core of Chemistry and Chemistry Connections and both versions of the periodic table to prepare for the National Challenge.


Next Generation Science Standards

CEF works with a team of chemistry experts and Next Generation Science Standardseducators, including professors and industry professionals, to develop the Challenge study materials. The materials align to the Next Generation Science Standards (NGSS) and include science concepts covered in many state assessments. Learn how each section of the study materials align to the NGSS:


Please note: CEF does not endorse or approve the use of any questions for the purposes of preparing for any level of the Challenge. Challenge competition questions (including the Qualifying Exam) are for competition purposes ONLY. Students should NOT receive or use questions (from the current year or any previous years) at any point to study. Use of Challenge competition questions for study purposes is grounds for disqualification.
