Favorite Demonstration: Demonstrating a Thermodynamics Fountain

Journal of College Science Teaching—May 2002

Cryogenic materials, mainly liquefied and solidified gases, are probably the most fascinating materials to use for demonstrating chemical reactions to introductory college students. A popular series of articles (Blachley 1997; Coppola et al. 1994; Haub 2001; Hughes and Haworth 1992; Stamm and Franz 1992) has been published presenting very effective and attractive demonstrations using liquefied gases. The authors describe two versions of a straightforward experiment that illustrates the concepts of energy/heat flow and conversion of heat to mechanical work. It uses a water fountain powered by the expansion of liquid nitrogen or dry-ice.

Bridging Science and Engineering

Journal of College Science Teaching—March/April 2002

The Colleges of Engineering and Education at Penn State University have collaborated to design and deliver an engineering course for education and other nonscience majors. In this course, students integrate basic principles of applied physical science and engineering to solve authentic design problems.

Reflecting on a Misconception: Can students see a full-length image in a small mirror?

The Science Teacher—February 2002

Looking at the reflection of our image in a mirror is so commonplace that most of us are unaware of the misconception we hold with respect to this phenomenon. This article provides an activity that will help students explore the concepts and relationships involved in reflection.

Learning Science and the Science of Learning: Science Educators' Essay Collection

Sure, you teach science. But do your students really learn it? Students of all ages will absorb more if you adapt the way you teach to the way they learn. That's the message of this thoughtful collection of 12 essays by noted science teachers. Based on the latest research, this is definitely a scholarly book. But to bring theories to life, it includes realistic scenarios featuring classrooms where students are encouraged to "construct" their own science learning.
