Describes three physics demonstrations: "Sticky Kinematics," dealing with motion in friction; "The Whistler," presenting a whistle-like sound of descending pitch from an iron spring; and "Magnetic Superconducter Mystery," generating a question why a magnet keeps spinning. (YP)

An activity to promote student understanding of the nature of science as a method of inquiry by engaging students in a real-life experience that requires them to utilize their critical thinking skills is designed. The activity links scientific concepts to the real world experiences of students and increase the relevancy of the content.

When identifying instruments that have had great influence on the history of physics, none comes to mind more quickly than the pendulum. Though first treated scientifically by Galileo in the 16th century, and in some respects nearly "dead" by the middle of the 20th century; the pendulum experienced "rebirth" by becoming an archetype of chaos. With…

We describe a service-learning course in which college students developed hands-on chemistry laboratory activities for elementary school children. These activities were then conducted with children both in area classrooms and in our own laboratories. This course allowed our students to apply their knowledge of chemical principles while introducing…

A science toy sometimes called the "magnetic spinner" is an interesting class demonstration to illustrate the principles of magnetic levitation. It can also be used to demonstrate Faraday's law and a horizontally suspended physical pendulum. The levitated part contains two circular magnets encased in a plastic housing. Each magnet stays…

Space science-oriented concepts and suggested activities are presented for intermediate grade teachers of science and mathematics in a book designed to help bring applications of space-oriented mathematics into the classroom. Concepts and activities are considered in these areas: methods of keeping time (historically); measurement as related to…
