Becoming a probation officer requires at least a bachelors degree in criminal justice, psychology, and/or social work. This career can be frustrating at times and immensely gratifying at others. Successful probation officers are firm yet gentle, have strong social skills, and are very organized.

Meterologists use highly developed instruments and computer programs to do their jobs. For example, they use weather balloons, radar systems, satellites, and sensors to monitor the weather and collect data. The data they collect and analyze are critical to understanding air pollution, drought, loss of the ozone layer, and other problems. Some atmospheric scientists work on teams with other scientists and engineers to find the best locations for new wind farms, which are groups of wind turbines used to generate electricity. Others work closely with hydrologists to monitor the impact climate change has on water supplies and to manage water resources. Atmospheric scientists need a bachelor’s degree in meteorology or a closely related field for most positions.
