Describes a joint project between a local secondary school and a feeder primary school to challenge students to produce an environmentally friendly green ink. The project involved children in developing new skills and boosted the profile of science in schools. (Author/CCM)

Discusses a classroom activity to trigger student interest early in a chemistry class. Describes a take-home exercise to convince students that a basic knowledge of chemistry is relevant to a better understanding of course topics in their majors. (CCM)

Finds that first-year college students can understand in detail the origin of the equivalent mass. Provides both a simple calculation derivation of this result as well as a noncalculus derivation. Argues that for every soft spring, the equivalent mass should be somewhere between m0/3 and m0/2. (CCM)

Describes a laboratory exercise to supplement or replace more traditional force table experiments, and adds real-world examples to this part of the introductory physics course. (CCM)

Explains a project called "Life Cycle of a Pencil" which was developed by the National Science Teachers Association (NSTA) and the U.S. Environmental Protection Agency (USEPA). Describes the life cycle of a pencil in stages starting from the first stage of design to the sixth stage of product disposal. (YDS)

Discourse analysis focuses on the negotiation concept to describe interaction between teachers and children in Mexican science classes in an elementary school. The interaction is seen as a collective way of developing Vygotsky's zone of proximal development (ZPD) in a cooperative context with the ZPD being the social product. (MMU)

A home kitchen can serve as a stockroom to provide the supplies needed to culture fungi for classroom use. Provides some alternative media and cultural techniques along with two alternative classroom investigations that can be employed in elementary through college-level classrooms. (Author/SAH)

Presents an activity on liquid chromatography that demonstrates the influence of mobile phase polarity on the separation of dyes with different solubilities. (YDS)

Discuses the counterintuitive fact that ice is a good insulator and creates a 'teachable moment' for describing the use of discrepant events as a strategy for science instruction and exploring a possible solution to the question, "How warm can the interior of an igloo get?" (Author/ASK)

Uses the GEMS guide, "Ants at Home Underground", to explore the life of ants and teach about them in a classroom setting. The activity applies students' knowledge of ants and students learn about ant colonies, what ants eat, and how they live. (SAH)

Presents an activity in which first grade students learn why camouflage is important to an animal's survival. Students see living examples of animals who use camouflage for protection, then create their own camouflaged animals and hide them around the classroom. For assessment, students write and illustrate five things they learned from the study…

Describes an activity to learn about meteorology and weather using the internet. Discusses the National Weather Service (NWS) internet site www.weather.gov. Students examine maximum and minimum daily temperatures, wind speed, and direction. (SAH)

Explains from fundamentals how the periodic table became the way it is and in doing so, touches on quantum theory and the important concept of symmetry. (SAH)

Describes a Science Technology and Society (STS) course for nonscience-oriented students in grades 10-12. The program comprises a collection of modules that present the scientific concept, its technological manifestation, and its societal relevance. (SAH)

Introduces the activity of making ice by boiling water with no external heat applied. Uses a vacuum chamber for the activity and explains the kinetic molecular theory of matter. (YDS)
