For this activity, I walked the girls through the Plan of Salvation, reading scriptures and discussing each part. We started in the premortal life where there was a war. (My original plan was to have the girls cut out pictures from church magazines and make a poster representing the Plan of Salvation, but I didn't have the room or the resources. So I had a bunch of old church magazines with no use, so I cut out pictures to decorate each station.)
Then we went through the door of birth,
and to earth.We talked about the creation, the fall, and the atonement. We discussed various pictures that related to earth life. Then we went through the door of death.
We went to the Spirit World, where our work continues and the Gospel is preached to those who haven't yet accepted it.
Then we went to judgment and resurrection, a door that is not possible without the Atonement of Christ.
We ended up in the Kingdoms of Glory.
The front of the room was bright and the rear was dark.
In the front (Celestial Kingdom), there were color pictures of temples and pictures of Christ. In the middle (Terrestrial Kingdom), there were black and white pictures of temples.
In the back, there were silhouettes and reflections of the temple.
At the very back was Outer Darkness.
Afterward, I gave them a diagram of the Plan of Salvation and instructions to go explain it to someone else to pass off.
Throughout the activity, I handed out candy for various things: bringing scriptures, sitting on the front row, helping people, finding scriptures first. At the end, I discussed how not everyone got the same amount. In the end, we don't all end up in one generic heaven. We go where we deserve to go--we get what we earn.
Hindsight advice: When it's this late in the year, it's too dark and cold to have "earth" outside.
