Read the scriptures
(By Stacey)

When I challenged the kids I used my radio from my 72hr kit as an object lesson. (Prs. Hinckley had challenged every member to read the Book of Mormons before Christmas 2005, challenge can be found in Ensign Aug 2005)

It is one that you have to hand crank to make it work. 

And we talked about how we had to be willing to do the work (studying and pondering) to help the scriptures work for us. 
We also related it to being "in tune" and listening to the right messages and how the Lord could give us information in an 'emergency'--I was able to relate this to things that the kids could think of to do with Katrina (hurricane in Sept. 2005) ....
