20、To discover whether bees can see colors, the following experiment is set up. A table is put in a garden and on the table is a piece of blue cardboard with a drop of syrup on it. After a short time, bees come to the syrup. The bees then fly to their hive and give the syrup to other bees in the hive. Then they return to the feeding-place which they have discovered.
After a while, the blue cardboard with the syrup on it is taken away. Instead of this card, a blue card is now put on the left side of the first feeding-place and a red card to its right.
