Presents activities to stimulate the curiosity of grade 10-12 students and introduce them to astronomical observations. Exposes students to the evolutionary theory of stars and the structure of the universe. (DDR)

Focuses on mapping activities designed to provide simulated experiences that help students understand the techniques used to measure and represent underwater terrain without making direct visual observations. (DDR)

Illustrates the use of an inductive approach that leads students to the discovery of Avogadro's number while integrating thinking, mathematical, and calculator skills in the process. An understanding of scientific notation and a calculator are required. (DDR)

Discusses the metric system. Presents an activity in which students construct their own standards of measurement by taking advantage of materials available in the classroom. (MKR)

Presents an experiment to demonstrate the diurnal and seasonal motions of the sun, which can be used in different grade levels, depending on the degree of difficulty required for the analysis, as an effort to generate student interest in the scientific method. Includes an activity to teach students elementary concepts of the sun's apparent motion…

Outlines a class project in which students explore characteristics of paper towels and paper towel advertising. Students design a variety of experiments related to paper towels and their claims. Provides four activities. (DDR)

Describes how you can lead students to erroneous inferences and conclusions by using demonstrations which point out to students the importance of carefully distinguishing between observations and inferences. (BR)

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)

Describes a field trip to study, collect, and analyze galls in the field and classroom. Students hypothesize about factors that cause gall formation, develop a basic understanding of the complex and fragile interactions between plants and insects that result in the formation of plant galls, and determine the broader role of galls within the…

Describes four court cases involving confrontation between the theory of evolution and the theory of creation: the Scopes trial, the Seagraves trial, Arkansas Act 590, and the Louisiana law. Provides 64 references on the issue. (YP)

Describes how high school biology students use the clam to study the bivalve body plan anatomy. Employs an open-ended investigation format that is rich with measurement opportunities including body mass, valve mass, and volume. (DDR)

Presents an approach that can help students to understand what happens in an experiment. Uses overlapping transparencies of both the experiment and the analysis. Includes details of the experiment and transparency preparation. (DDR)

Describes an exhibition-based activity set that teaches important psychological processes such as attention (Interference), communication (Pattern Talk), and cooperation versus competition (Do Nice Guys Finish Last?). Activities follow the scientific method, and teachers can observe varying levels of skill and cognitive development in students of…
