If you like, you can measure the daily growth of the bacteria colonies by using a felt-tip marker to trace a circle around each colony on the bottom of the petri dish. After several days, you should have a collection of concentric rings on the bottom of each dish.
Alfred Adler was a physician, psychotherapist, and the founder of Adlerian psychology, sometimes called individual psychology. He is considered the first community psychologist, because his work pioneered attention to community life, prevention, and population health.
Alfred Adler (1870-1937), world renowned philosopher and psychiatrist, stressed the need to understand individuals within their social context. During the early 1900's, Adler began addressing such crucial and contemporary issues as equality, parent education, the influence of birth order, life style, and the holism of individuals. Adler believed that we all have one basic desire and goal: to belong and to feel significant.
