5.14 Response and damping
How do different instruments produce the sounds we classify as music? How do we decide whether something – a piano, a vacuum cleaner – is actually a musical instrument? In this unit we investigate the way vibrations and sound waves are harnessed to create music.

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

Jakobshavn Glacier Ice Flow (WMS)
Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. However, from 1997 to 2003, the glacier has begun to recede again, this time almost doubling in speed. The finding is important for many reasons. For starters, as more ice moves from glaciers on land into the ocean, it raises sea levels. Jakobshavn Isbrae is Greenlands largest outlet glacier, draining 6.5 percent of Greenlands ice

AMSR_E Pacific Sea Surface Temperature Data Used to Forecast 2003 Hurricane Season
Researchers and forecasters often study sea surface temperatures for an activity predictions for 2003 in part to changing conditions in the Pacific Ocean, such as the demise of El Nino. This sequence traces the evolution of the warmer-than-normal waters associated with the weak El Nino that developed in the late fall of 2002. By January, the warm conditions began to dissipate. Fewer than normal hurricanes generally form when El Nino is present. Researchers say the Pacific may transition to the c
