Lesson on will and might (possibility)

I have been asked to create a lesson to level 1 students about will and might and the fact that there are differing degrees of certainty. I was wondering if anyone had any ideas what context I could use, and where I could find some resourses to back me up. I have "How English Works" by Micheal Swan.

Any help would be great:-) :up:
