Language arts and science activities are combined in a program based on the adventures of an imaginary character. (DD)

Describes needed equipment and procedures for shattering a glass goblet with the amplified output of an audio oscillator. (MLH)

Describes the development of a program to establish in-school salvage systems for school-generated and nonschool-generated waste materials. Students from conservation classes became involved in collecting waste from "recycle" boxes in every classroom, in field trips, newspaper drives, and salvage of aluminum cans. (CS)

Presents a selection of fascinating physics demonstrations that look impossible but that can be done with some knowledge of physics and some practice. Includes four demonstrations that illustrate free fall motion and the center of mass of a system. (DDR)

Reports on research that has identified an appropriate policy model for emergency anticipation in high schools that was developed from an analysis of the literature and the law. Presents a model emergency anticipation policy for high schools together with policy statements in first aid, respiratory equipment, fire, chemical storage, and waste…

Describes a project that enables students to emulate a scientist in the classroom setting through collaboration on research projects, use of research literature, and communication with scientific peers. Student groups focus on investigations of the cellular and molecular aspects of a disease. (DDR)

Describes how to use various types of licorice ropes to illustrate the similarities between RNA and DNA. Specifically addresses illustrations of replication, transcription, protein synthesis, mitosis, meiosis, mutations, and anomalies. (DDR)

Reports on an exploratory study of how people see and explain a prominent exhibit (Tornado) at an interactive science museum (the Exploratorium). Data was assembled using a novel, technically mediated activity system (Video Traces). Argues that Video Traces is an effective tool and discusses an expanded Video Traces system. (Author/DKM)

Presents activities in which students play the role of cadets performing missions for the fictitious SETI (Search for Extraterrestrial Intelligence) Academy. Guides students toward an understanding of evolutionary forces and how they are affected by the physical environment. (JRH)

Describes the experiences of two first-year teachers who joined forces for implementing an integrated biology/English unit. Discusses insights gained during the experience. (JRH)

Describes a project that enables students to apply their chemical knowledge and business sense in a real-world activity. Involves forming companies that compete against each other to produce two pounds of the best quality soap. (JRH)

Describes a constructivist approach to teaching about the phases of the moon. Addresses student misconceptions and encourages students to focus on the causes of the phases of the moon. (JRH)

Focuses on two aspects of literacy related to science performance: interpretations of science task cards depicting a series of activities and written language samples summarizing science tasks. Results highlight difficulties that students experience in developing and expressing their understandings of science activities. Illustrates the need to…

Describes a strategy for teaching astronomy using sky lore from different cultures. Presents an activity in which students invent their own constellations and create myths to accompany them. (JRH)

Presents a lesson that uses the learning cycle to introduce the concept of classification and the use of dichotomous keys to identify plants and animals. Encourages students to become better observers and helps them gain confidence and experience in using simple classification keys. (JRH)
