Karl Von Frisch is famous for his
study of bees. In one of his experiments he marked a
few bees by placing a white spot on the thorax of each
bee. Von Frisch then prepared a solution of sugar in
water which he scented with lavender. He placed this
solution on a table which was 2000m from the bee's
hive. He then allowed his marked bees to feed on the
Von Frisch placed other tables at
various distances from the hive. Each of these tables
was scented with lavender but there was no food on
them. All of the tables, including the one at 2000m,
were placed in the same direction from the hive.
Von Frisch placed an assistant at
each table. Each assistant counted the number of
unmarked bees which visited the table during the same
thirty minute period.
