Bacterial viruses, otherwise known as bacteriophage (or phage), are some of the most abundant viruses found in the environment. They can be easily isolated from water or soil and are ideal for use in laboratory classrooms due to their ease of culture and inherent safety. Here, we describe a series of 10 laboratory exercises where students collect,…

Students in introductory physics courses often don't study thermodynamics or thermodynamic events. If any thermal physics is taught in introductory courses (e.g., Physics 101 for Liberal Arts Majors), it usually involves the concepts of specific heat and various temperature scales. Seldom are the first and second laws of thermodynamics taught in…

Open-ended, inquiry-based multiweek laboratory exercises are the key elements to increasing students' understanding and retention of the major biological concepts. Including original research into undergraduate teaching laboratories has also been shown to motivate students and improve their learning. Here, we present a series of original…

Provides a series of learning center activities which demonstrate concepts about air. (CP)

Discusses the laboratory portion of a beginning noncalculus physics course that uses concrete examples of abstract concepts. Describes the use of coffee cans to explain oscillations and plastic darts to illustrate collisions. (MLH)

Many words which have been treated in the denotative sense are actually connotative in nature. That is to say that citing a definition or stating a fact should not be a learning goal. Rather, a "conceptualization" should be what teachers are striving for. A series of activities dealing with density have been provided for demonstrations or…
