Tories: Fighting for the King in America's First Civil War
Most Americans have learned the essential narrative of the American Revolution: Our Founding Fathers led proud Patriots to fight against British rule and ultimately prevailed. Rarely mentioned are the thousands of Tories, or Loyalists, who supported the British and fought to remain in their American homes as loyal subjects of the crown. Historian Thomas B. Allen contends the American Revolution was as much a civil war as it was a rebellion against the British. Thomas B. Allen is the author or c

Trash to Treasure!
Student teams use the engineering design process to create a useful product of their choice out of recyclable items and "trash." The class is given a "landfill" of reusable items, such as aluminum cans, cardboard, paper, juice boxes, chip bags, egg cartons, milk cartons, and etc. and each group is allowed a limited amount of bonding materials, such as duct tape, hot glue and string. This activity addresses the importance of reuse and encourages students to look at ways they can reuse items they

Glowing Flowers
Student teams learn about engineering design of green fluorescent proteins (GFPs) and the use of GFPs in medical research, including stem cell research. The use of GFPs is simulated by adding fluorescent dye to water and allowing a flower or plant to transport the dye throughout its structure. Students apply their knowledge of GFPs to engineering applications in the medical, environmental and space exploration fields. Due to the fluorescing nature of the dye, plant life of any color, light or da

Swinging Pendulum (for High School)
This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by using the equations for potential and kinetic energy. The equations will be justified as students experimentally measure the speed of the pendulum and compare theory with reality.
