Bees are very small animals which fly through the air to look for flowers for food. Bees have been studied by Karl Von Frisch who won a Nobel Prise for his work. He studied bees’ activities when they returned to their home called a hive. When a bee found some food, it returned to their hive and danced. The dance was the way the bee communicated to other bees the fact that it had found food.
    Bees do two kinds of dances to tell other bees of their discovery of food. First, there is a round dance. In this dance, the bee moves in a circle inside the hive. The round dance is used when food is close by. The food must not be more than ten meters away. If a bee comes back and does a round dance, the other bees know they must go out and look for food nearby. The bees also smell the bee that has found the food. The smell tells them what kind of flowers to look for. After watching the round dance and smelling the bee that has found the food, the other bees can find the food source.
    A second kind of dance done by the bees is a tail-wagging dance. In this dance, the bee wiggles the end of its body as it moves in a straight line. The tail-wagging dance is used when the food is far away. The bee knows from the speed of the tail-wagging dance just how far away the food source is. The line the bee dances on the tail-wagging dance, the bees also smell the bees that have found the food. The smell tells them what kind of flowers to look for. After watching the tail-wagging dance and smelling the bee that has found the food, the other bees know three things. They know how far to fly, what direction to fly in, and what kinds of flowers to look for.
