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”.
History and Geography are no longer boring and dry, and the material provides a wide variety of topics.
