Assessed the level of cognitive demand inherent in the manner in which students were held accountable for activities and tasks in seventh grade life science classes. Notes that most tasks placed minimal cognitive demand on students, as they involved copying or simple step-by-step procedures. (SKC)

Describes a lesson designed to help young students conceptualize cholesterol and its effects on the body. Provides young students with a concrete way to understand how cholesterol builds up in blood vessels and restricts blood flow. Includes a simple illustrative experiment for children to perform themselves. (CW)

Presents criteria for having students make their own games which are used by the class to review material covered in life science. Students are required to use recycled materials in producing the game and its accessories. Samples of some of the games produced are included. (TW)

Activities, experiments, computer programs, equipment, procedures, demonstrations, and teaching techniques are provided for a wide variety of topics in the biological and physical sciences.

Ranger Rick's NatureScope is a creative education series dedicated to inspiring in children an understanding and appreciation of the natural world while developing the skills they will need to make responsible decisions about the environment. The topic of this issue is "Wading into Wetlands." Contents are organized into the following…

A report of a task group on biomedical patents summarizes the context in which technological innovation involving research institutions and industry takes place and the interests and concerns of various participants. Suggestions are given for accommodating these concerns through institutional policies and procedures. (MSE)

Results of this study suggest that diagrams provide different types of information for ninth-grade students (N=273) and that learners process each type differently. Flow diagrams running across a page from either left to right or right to left, or with or without drawings of dinosaurs, were used. (JN)

Describes Waunakee Community School's six-week Summer Science Program for students entering the seventh grade. Students are selected for this science enrichment program on the basis of interest, ability, and maturity. Program content includes wetlands, forests, prairies, and animals, concluding with a camping trip. (DS)

Discussed is the intertidal region and the characteristics and adaptations of the organisms that live in that region. Several activities that involve the intertidal region are described, which reinforce the adaptive behaviors and forms of the organisms found in the intertidal region. (Author/DS)

Several potential safety problems are identified relative to science teaching: the use of bottled gas or alcohol lamps as heat sources, the hazards of Millon's Reagent for testing for proteins, and the use of silicon tetrachloride to demonstrate properties of chlorides. Science teachers are also warned about potentially dangerous procedures…

The use of live animals in the secondary school laboratory is discussed along with suggestions for increasing the use of live animals and challenges to those teachers who restrict this use. (SA)

A paper model which is designed to give students a hands-on experience during lecture and blackboard instruction on DNA structure is provided. A list of materials, paper patterns, and procedures for using the models to teach DNA structure and replication are given. (CW)

The use of living animals in the classroom is discussed. A checklist of ideas to remember when considering housing animals in the classroom is provided. (CW)
