TED-Ed has created a set of videos with complete lesson plans, quizzes, discussion and further research topics for each of the elements in the periodic table. They’re called the Ted-Ed Periodic Videos.
The online system also allows you to adapt the lessons to your own needs and re-share that. This looks like an awesome resource, well worth having in your “toolkit”.
The activities embedded in the programs make the subjects more engaging for the students as well as the teacher.
