1 Dividing the planet

A good globe can set you back quite a lot of money. Of course, I don't mean the little moulded plastic planets or the globes you can blow up as if the world were a beach ball, but the decent sized ones that sit solidly on turned wooden bases and quietly emanate authority from the corner of a room. Yet these days, it hardly seems worthwhile making such an investment. Countries appear to change their colour, their shape or their name with remarkable rapidity.

It has become a cliché t

Engineering is about extending the horizons of society by solving technical problems, ranging from the meeting of basic human needs for food and shelter to the generation of wealth by trade. Engineers see the problems more as challenges and opportunities than as difficulties. What they appear to be doing is solving problems, but in fact they are busy creating solutions, an altogether more imaginative activity.

Focus on Fabrics: Putting Materials to Good Use
The goal is for students to understand the basics of engineering associated with the use, selection, and properties of fabrics. A wide variety of natural and synthetic fibers are used in our clothing, home furnishings and in our travel and sports equipment. The specific material chosen for each application depends on how closely the properties of the material match the design needs. This unit focuses on the different characteristics of fabrics and shows students how natural and synthetic fabrics

Dickinson Magazine - Turtle Tagging
Dickinson Magazine Feature Video: In April, students in Gene Wingert's Introduction to Field Biology lab teamed up to capture and tag turtles in Wildwood Park in Harrisburg, Pa. The project had a two-fold purpose: track population and growth rates while raising funds for Wildwood Park through an Adopt-a-Turtle event. All "adopted" turtles were later released back into the wild; meanwhile, students had hands-on experience with field research. Assisting Wingert (who directed the project from behi
