Examples of equilibrium are evident everywhere and the equilibrium rule provides a reasoned way to view all things, whether in static (balancing rocks, steel beams in building construction) or dynamic (airplanes, bowling balls) equilibrium. Interestingly, the equilibrium rule applies not just to objects at rest but whenever any object or system of…

Sound is typically thought of something that is heard. Can it be seen or felt? Most students experience the noises that surround them in everyday life, but few stop to think about what sound is, how it travels, and the biological challenges associated with perceiving sound. Since students are already familiar with everyday sounds, inquiry-based…

In our science for non-science majors course "21st Century Physics," we investigate modern "Hubble plots" (plots of velocity versus distance for deep space objects) in order to discuss the Big Bang, dark matter, and dark energy. There are two potential challenges that our students face when encountering these topics for the…

It seems each new school year brings its own opportunities to grow as an educator. As teachers in a STEM focused school that serves primarily at-risk students, the authors face a new challenge in rethinking their instruction to align with the "Next Generation Science Standards". This involves changing the focus of units previously taught…

Two articles are presented in this column. "Life in an Auto Factory: Simulating how Labor and Management Interact" by Eric B. Freedman describes a classroom simulation of management and labor relations in an auto factory. Classroom handouts are included. The next article, "Women of Action and County Names: Mary Musgrove County--Why…

The Calculator Controlled Robots activities are designed to engage students in hands-on inquiry-based missions. These activities address National science and technology standards, as well as specifically focusing on mathematics content and process standards. There are ten missions and three exploration extensions that provide activities for up to…

Discusses the searching process for students attempting to obtain meaningful information about which to write. Presents methods and benefits of searching which improve students' technical writing. (MS)

Argues that journal writing expands students' discoveries about themselves as writers, and extends their abilities to take charge of writing assignments in both English and non-English courses. (MS)

Reviews Kenneth Pike's tagmemic theory and its application to rhetorical concerns generally. Explains his epistemological assumptions. Presents a model for speech classroom use, which allows rhetors to channel their thought processes consciously and to vary their perspectives in search of a fuller understanding of any subject. (PD)

Describes role-play centers in which children can do math problems, invent, experiment, write with a purpose, and act out adult career roles. Examples of centers include a doctor's office, a supermarket, a fix-it or inventor's workshop, a post office, a pet store, a zoo, a veterinary clinic, a museum, and a restaurant. (DKM)

This instructional packet deals with inventions and presents activities that enable students to learn about past inventions and inventors and also create their own inventions in a variety of ways: centers, individual work, and group work. (JRH)

Seven easy-to-do experiments with plants are outlined to aid in teaching children about plants: their search for water, food, and light; a variety of rooting systems; and the effects of soil temperatures. (JMF)

Presents a demonstration that attracts and then repels soap bubbles to a Van de Graaff generator. Discusses theory and describes the event that led to the development of this demonstration. (JRH)

Proposes three basic strategies of inquiry essential to good writing and reports the results of studies on these strategies. (JL)

Presents the story of the accidental invention of the Wardian case, or terrarium, by Nathaniel Bagshaw Ward. Advocates the use of this story in teaching precollege biology as an illustration of how a chance event can lead to a major scientific advancement and as an example of the common occurrence of multiple discovery in botany. Contains 34…
