How did one bee commu-nicate the news of food to others

?

Professor von Frisch marked some bees with little dots of colour.

The marked bee performed a circle dance, and the surrounding bees copied it and left for the feeding place together.

The circle dance communi-cated the news of food.

Results Conclusion

Did the dance convey more informa-tion?

Professor von Frisch set up two feeding places, one close to the hive, the other much farther away, and marked the bees with two colors.

Bees from nearby feeding place did circling dance, while bees from the distant one did a wagging dance.

The two dances told the bees about the location of the feeding place.Para.4

Experiments Results Conclusion

How did bees tell the exact distance of the feeding place?

Zoologists moved the feeding place slowly farther, and use a stop-watch to count how many times the bees repeated the dance per minute.

The farther away the feeding station was, the slower the dance was.Para.5

The number of wagging dances per minute told the exact distance of the feeding place.

Experiments

Results Conclusion

Could bees tell each other the exact position of a feeding place?

Scientists obtained more data and did more experiments.

The zoologists clarified the procedure by which bees communicate information they use to find and fetch food.
