I have revised our growth and development curriculum for 4th, 5th, and 6th grade. There are many videos out there and one of my favorites is from National Geographic entitled, "Human Reproduction". There is an excellent web site that provides course content, teaching strategies, handouts, and evaluation methods: http://www.HealthTeacher.com/ This web site also provides many other good web sites. Let me know if you would like to review a copy of our 6th grade curriculum.We could share the good and eliminate the bad. Florence
