Kinetic and Potential Energy of Motion
In this lesson, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum, illustrating the concept of conservation of energy. Students calculate the potential energy of the pendulum and predict how fast it will travel knowing that the potential energy will convert into kinetic energy. They verify their predictions by measuring the speed of the pend
Swinging with Style
Students experientially learn about the characteristics of a simple physics phenomenon the pendulum by riding on playground swings. They use pendulum terms and a timer to experiment with swing variables. They extend their knowledge by following the steps of the engineering design process to design timekeeping devices powered by human swinging.

"A Less Reliable Form of Birth Control": Miriam Allen deFord Describes Her Introduction to Contracep
Despite major cultural, legal, and medical impediments the use of birth control, including abortion, by American women was widespread at the turn of the century. In their quest to control unwanted pregnancies, American women could be surprisingly resourceful in the methods they used. In this audio excerpt from a 1974 interview with historian Sherna Gluck, Miriam Allen deFord described methods of birth control in vogue in the 1910s, including spermicides, douches, the Dutch pessary (an early diap
"It Is Entirely the Bolshevik Spirit": Mill superintendent W. M. Mink Explains the 1919 Steel Strike
In the dramatic 1919 steel strike, 350,000 workers walked off their jobs and crippled the industry. The U.S. Senate Committee on Education and Labor set out to investigate the strike while it was still in progress. In his testimony before the committee, W. M. Mink, mill superintendent at the Homestead steelworks, testified that the cause of the strike was simple--the infection of "the Bolshevik spirit"among "the foreigners."
