Here is what we did:
A set of wooden building blocks were divided equally into two groups.
1. Blocks with "regular" shapes of rectangles and squares. They were labelled (with masking tape) with words like "wisdom, patience, kindness, love, joy, self-control, forgiving, honest, prayer, worship God, etc.".
2. Blocks with "irregular" shapes like cones, cylinders, triangles, arches, rounded and sloping shapes which can be difficult to build with. They were labelled with words like "foolish, selfish, hatred, envy, loves money, likes to fight, faithless, prejudice, worship idols, etc.".
All blocks were placed in a box and the children pulled them out one by one and decided if they described "wise" or "foolish" behavior and placed them on two separate tables. The children split into two groups of builders, one wise and one foolish. Each group built a single house with their blocks on the separate tables. They were instructed to make their house as strong as possible.
After the children admired both houses, the leader pounded with fists on the table of the foolish builders' house, to imitate an earthquake. The "foolish" house made of the fancy-shaped blocks fell over quickly (much to the delight of all the builders). The "wise" house was next. The fist-pounding did not knock over the well-built "wise" house.
Discussion followed.
