Everything in nature follows a pattern. Circles, lines, spirals, and angles are repeated to make a design or a pattern. Patterns in nature are not just pretty adornments. They do serve a purpose that has helped nature survive and flourish.

Have you ever taken a close look at a beehive? Well, not too close or you might get stung! The natural pattern in beehives is so perfect that it seems to be computer designed. The hives are made up of layers and layers of cells. Each cell has perfectly equal six sides or hexagons. Why would bees build six-sided cells, instead of circular or box shaped ones? That is because the bee is a genius at geometry and architecture! Six-sided cells use up every bit of space and allow bees to get maximum area for storing honey. Hexagons also use the least building material because all six sides are common to other cells. The bees don’t waste space, material or effort. Aren’t they smart insects?
