storyboard

I am currently in the brainstorming part of my video project, and I am struggling with how to make a supplemental video that will address that needs of a student in my content area without making it just a video of me teaching something. I am considering just doing it over rock types and explaining different properties of rocks and how they differ from one another. I've spent a lot of time on planes and in airports this last weekend, and that time was used to think about the project. However, I wasn't able to write anything down because I didn't have my school gear with me. I have probably been thinking about how to do this project for about 3 hours (3 hours that I have focused on thinking about this project).
