Have the children make 5 standups to represent the five armies who were attacking Gibeon and 1 standup to represent Joshua's army. Use Trix to represent the hail stones which God sent down from the sky against the enemy armies. The children can rain down the hail the the 5 enemy armies. Attach a round sun to a popsicle stick to reinforce about God stopping the sun in the sky so the daylight would last longer. God can do anything!
