This article describes a design activity that provides students with a solid understanding of the many issues involved with alternate energy system design. In this activity, students will be able to learn about electric vehicles and have the opportunity to design a way to recharge the batteries while the cars are parked in a commuter garage. The…

Greenhouses are marvelous devices, allowing one to enjoy the flower spectacle of summer all year round. At night, greenhouses use supplemental heat to keep the fragile plants warm. Over the last 30 years, greenhouse technology has undergone many changes, with the structures being automated and monitored and low-cost plastic structures emerging as…

Large tractor-trailers have a reputation of being involved in rather horrific accidents, often involving death and carnage among smaller passenger vehicles. The giant rigs, according to some transportation experts, may have outlived their usefulness on crowded highways, and perhaps it is time that people rethink their presence on the roads. In…

National Aeronautics and Space Administration (NASA) has already sent many technological instruments into outer space. All these instruments were designed and built especially to operate in harsh and alien environments. How do NASA engineers know what kinds of planetary instruments to develop in the first place? Well, they ask. Once engineers…

In this article, the authors examine which nontechnical competencies or soft skills related to technology education should be developed by high school students. Results clearly indicate that university-level engineering and engineering technology professors rate students' interpersonal, communication, and work ethic competencies as desired…

Engines, in their many forms and functions, have had a tremendous impact on society and the environment. It is hard for the contemporary student to fathom a world without trains, cars, trucks, powerboats, and airplanes. With the fascination, history, impacts, and importance of engines to modern society, it is only natural that engine technology…

In this article, the author describes an activity he introduced to his engineering drafting students that involved a Tootsie Roll product. In this particular activity, he assigned his students to find out how many licks are needed to get to the center of a Tootsie Roll Pop. He first asked his students to do some research if an answer exists for…

Examines some of the forces that create change in occupations, shows the types of newly developing and much-needed careers fostered by technological advancement, and demonstrates how to pursue education and training in preparation for entering one's chosen career. Careers include engineer, scientist, technician, craftsperson, and researcher. (CT)

To prepare students for several changes in careers during their lifetime, Technology Challenge is a program designed to meet the challenges in the evolution of technology education from traditional industrial arts. In a laboratory setting, students solve real-world problems using computer technology. (JOW)

Bridge construction is a popular classroom activity. However, the basic principles of tension, compression, and counterbalance are not always clearly represented and defined. The common materials used to construct model bridges, such as straws, toothpicks, Legos[TM], and building blocks, are often too flexible or stationary to demonstrate the…
