After a little digging, I came across a section devoted to lesson plans. The Social Studies section had nothing for psychology, but the Family and Consumer Sciences Education section had over thirty lessons devoted to Child Development.
While I doubt if any of these child development lessons could transfer directly to a psychology course, I have a feeling there are a few "gems" in there. My thought was, with a major break coming next week, some of you who frequent the THSP Blog might have the opportunity to do some "mining" of those lessons and either leave your results in the comments section or email them to me for a posting.
