While movie screens and televisionshows put a spotlight on lawyers, doctors and policemen (and occasionally also on forensicscientists), they only occasionally pick entrepreneurs as the characters of interest.This paper has identifies and reviews a number of known and available portrayals ofentrepreneurs in feature films.

Undergraduate Research (NCUR) has been an annual conference since 1987.NCUR’s primary goal is to promote undergraduate research in all fields of study.National Science Foundation (NSF) funds undergraduate research through Research Experiencesfor Undergraduates (REU) program. Providing research experiences for undergraduate studentsand increasing the number of students interested in graduate programs are the goals of the REUprogram. Students work on REU projects during summer months for 8 to 10 weeks. REUprograms entail several benefits to students including increased awareness of their discipline andtechnical expertise, better career opportunities, gains in confidence levels, and elevated likelihoodof pursuing graduate degrees and research careers.6

student thatmay be working can be taking another class only offered at that specific time during their workhours. This often is the result of a lack of professors at a university, but the students are the oneswho have to pay for it. With such little scheduling flexibility, students are often forced to delaytaking a class they to graduate promptly. As a result, a lack of course availability pushes theirgraduation back, and increases the amount of tuition they have paid at the end of their collegecareer.

Interest, not performance, hasbeen shown to be a greater predictor of choosing to concentrate in STEM1. However, schoolsoften neglect the engineering component of STEM. Consequently, extracurriculars such asscience centers must play key roles in influencing children by fostering interest in engineering.Taking advantage of the popular tinkering and Do-It-Yourself Maker movement, increasinglymore science centers are offering engineering and maker programs.
