CALIFORNIA SCIENCE & ENGINEERING FAIR
2022 PROJECT CATEGORIES

CSEF_Bar
Students:
Do not assume that your project belongs in the same category that it had in the previous competition.
Every science fair uses its own unique categories and their definitions. Read through all of the category definitions below to find the one that best describes what you studied in your project. For convenience the categories have been organized broadly into groups, but do not limit your category search only to one group. For example, studies of the effects of a chemical on a plant might, depending upon the details, be classified either as Plant Biology (in the Life Science group) or Toxicology (in the Environmental group). Read all of the definitions of possibly relevant categories.
Your project may still be moved to a category different from your preference
All projects will be reviewed for appropriateness in the requested category by the judges in that category based upon your Project Presentation. Do not assume that your project will remain in the category you request. All such changes in category will be effected by one week prior to the Fair and announced on this web site. If your project&rquo;s category is changed, you will be informed directly.
