• I've long wanted to partner with the local science museum to have a Psychology Day. Students could demonstrate psychological principles. We would have some lectures on topics of general interest. I would invite high school teachers of psychology to bring their students and have an activity for the teachers so they could get CE credit. Both APA and APS have grant programs that I think would support this effort. The same kind of activity could be done with libraries.
• Speak at teacher professional development days on relevant topics. This can be college or high school level.
