This article presents a laboratory approach to teaching the scientific method. Students are given a problem that can be solved by testing their hypothesis in the laboratory. The exercise is designed to introduce scientific methods to junior high students. A sample student data form is included in the article. (MA)

Presents contributed laboratory techniques and demonstrations aids. (CP)

Science activities and laboratory techniques suggested by contributors for use in the middle school are provided. (CP)

Suggests ways in which hens' egg vitelline membranes can be used to demonstrate cell traction effects. Reviews procedures for using and culturing the membranes and identifies topic areas for student projects. (ML)

Describes how a science challenge program was modeled after the Olympics to offer a variety of science events in a competitive setting. Reviews organizational factors, suggests sources for events, and identifies rules and scoring procedures. (ML)

Introduces 12 activities for teaching science. Includes one way to begin the school year, peristalsis demonstration, candy-coated metrics, 3-D constellations, 35-mm astrophotography, create an alien organism, jet propulsion, computer programs for pendulum calculations, plant versus animal, chocolate chip petroleum, paper rockets, and…

Introduces a bubble-making method for discussion about surface tension and thin film interference. Provides some pictures and list of materials for the apparatus. (YP)

Deals with a diffraction experiment using wrapping paper. Provides a magnified picture of the paper, a diffraction diagram, and some instructional information. (YP)

Describes a project for junior high and senior high school students designed to safely preserve hard-bodied marine invertebrates. Details the materials and procedures used in this technique. Stresses the use of non-toxic solutions and producing a lifelike specimen. (CW)

Describes a program known as "Explorations" within the Camp Lejeune Dependents' Schools (North Carolina) which is based on bringing the outside world to the student. Discusses the activities developed around the theme "Oceans: Harvest of the Sea." (TW)

Describes a simple method to teach molecular geometry using styrofoam balls and velcro strips. Discusses the construction and a procedure for using the model for teaching. (CW)

Provides background information on the equipment and knowledge necessary to do an astronomy activity on the earth's rotation. Details an activity in which students can measure the rotation of the earth using a camera and the stars. (CW)

Describes how short-term laboratory projects were used to teach population and community ecology to undergraduate environmental science students. Directed students to formulate and implement their own hypotheses and experimental designs. Uses questionnaire results and written reports to assess the contribution of the course to student…

Describes the development of a robot whose mainframe is essentially transparent and walks on four legs. Discusses various gaits in four-legged motion. Reports on initial trials of a full-sized model without computer-control, including smoothness of motion and actual obstacle crossing features. (CW)

Presents several teaching suggestions associated with the raising of monarch butterflies in classrooms. Emphasizes how this endeavor can be used to enhance the use of science process skills. (TW)
