Make sure there is a question and answer time. Have the students write thank you notes. Arrange trips at least two weeks in advance. After the first year, this is usually simple to set up with the same employer year after year. Have the students brainstorm and write down questions prior to the excursion.
Partners are a good idea.
Have one adult for every eight to ten students. Provide time to debrief the students on return from the experience. Discussions and sharing of people in the news, in history, on TV and in the movies can be excellent ways to put careers in your classroom. Reading books and watching videos are prime times for career awareness activities. Workplace skills are taught in the classroom daily.
