AI, Graphics and Field Work
Need help on how to use AI with your science/engineering fair project? See the ISEF Tips and Guidelines to guide your work.
Reminder to all students—credit all graphics. Review the D&S Graphic Credit Guidance. Please be aware that all graphics must be individually cited, graphics obtained from the Internet must include the URL from which they were obtained in their citation, and graphics created by students must be cited with the year they were created and the program used. When creating your materials for your Project Board for fair day. Students should verify any references, credits, or citations generated by AI to ensure their work is not submitted with false or incorrect sources.
Also, ISEF has published a new guide to Field Work. If your project involves field study, please check this out!
