Science, Technology, Engineering, and Mathematics (S.T.E.M.) programming is becoming increasingly popular in public libraries. However, facilitating these programs can be expensive and smaller libraries, including Gretna Public Library's teen department, often struggle to fund them. By interviewing other teen librarians in similar situations and researching community resources, I was able to create a S.T.E.M. focused programming guide for the Gretna Public Library teen department. This guide specifies the budget, materials, time, and space needed for each program, as well as other resources they can share with their teens.
