Also making a sort of game out of it, practicing the plan over several times, and having them draw or color pictures about the plan and even making a cute poster for the refrigerator are all good ways to help them remember what to do. Remember all the drills in school where we lined up and marched outside? And the practice of crawling under our desks? I can remember when we had the Cuban crisis, I was a young adult and I was pretty frightened about possibly being bombed by Castro. (I lived in California at the time) So it is important to educate, but to do it in a manner that does not overly frighten youngsters.
