Problem:
Karl von Frisch studied the interactions between bees and flowers. He wanted to know how bees select which flower to go to. In particular, he wanted to know whether the bees could see different flower colors and would, therefore, select flowers based on their color.
In his first experiment, von Frisch put out pieces of red- and blue-colored paper, each of which had a bowl on top. In the bowl on the blue paper, he put sugar water; he left the bowl on the red paper empty. Bees discovered the sugar water in the bowl on the blue paper and ate it, returning again and again with other bees to get more.
After a while, von Frisch took away the papers and bowls. He replaced them with two new bowls with colored paper, identical to the first pair except that both bowls were empty this time. He found that bees swarmed around the bowl on the blue paper, ignoring the bowl on the red paper.
Required:
Question 1: What was von Frisch's hypothesis?
Question 2: What conclusion should von Frisch draw from his results?
Question 3: What observation would have falsified von Frisch's hypothesis?
Does anyone know how to go about this search to explain it.
