Contact your public information officer and let them know that you would like to give a lecture.
Determine the venue for your lecture.
If you plan to give the lecture at your institution, contact the appropriate people there to help with local logistics. Other venue ideas are museums, community centers, libraries, clubs and organizations, or local Science Cafes. These may require additional legwork, but your public information officer may be able to help.
Select a date. When possible, allow at least two months to publicize your lecture and organize logistics.
Check out the many resources available for general audiences to help prepare for your lecture.
After you give your lecture, if a video of your presentation or your slides are available online, please send your information and a link to Kathryn Grim. She will add your lecture to the Virtual LHC Lectures page to help others planning LHC lectures.
