Describes a class project to determine which environmental condition, such as light, heat, and type of basking substrate, would result in the least and most turtle basking behavior. (PR)

Describes how students in grades 2-8 can make beakers from quart-sized oil containers and calibrate them in milliliters. In an second activity, students estimate the volume of water in four jars and use their beakers to measure the water in each. The estimates are compared to the true measurements. (PR)

Describes a simulation of chemical reactions to help students understand factors that affect the rates of chemical reactions. (PR)

Listed with examples are six levels of thinking. The design of lessons to teach higher order thinking is discussed. A sample lesson on spontaneous generation which uses this method is provided. (CW)

The improvement in student attitudes as the result of the use of videomicroscopy in the science classroom at the elementary, secondary, and college levels is discussed. The results of published research studies are reviewed. (CW)

Presents methods and questions for discussion, activities, role plays, and assessment methods for helping students understand the importance of water conservation. (PR)

The MOONBASE AMERICA project involved teachers and 96 secondary school students who participated in the project by helping to build MOONBASE, taking a space science course, creating a communications network, and completing a 7-day simulation in the MOONBASE structure. Teacher and student outcomes were evaluated. (MDH)

Describes activities to help students understand pH scales and acid rain. (PR)

The purposes of this paper are (1) to demonstrate that medical microbiology laboratory exercises should be presented with a focus on medical applications, not just traditional microbiology and (2) that exercises devoted to differential diagnostic decision making can be used to enhance the problem solving of students. (PR)

Describes a class activity of conducting a mock trial of a pretend situation of a white-tailed deep population creating problems for a town. Procedures, fact sheets, names, and descriptors of characters are provided. (PR)

Examines the following five teaching techniques that have strong motivational value: (1) study groups, (2) group projects, (3) sharing information, (4) computer-assisted instruction, and (5) field trips. (PR)

Presents a list of 11 advantages that hands-on science instruction has over science instruction via television. Teaching methods encourage activities that appeal to sensual stimulation, problem solving, student interests, and cooperative learning. (MDH)

Describes an activity that shows how understanding a modern coral reef environment helps predict the location of old subsurface reefs that may contain oil. (PR)

Describes how science fiction films can be used in science instruction. (PR)

Describes a program that introduces students to hands-on, minds-on science and provides an opportunity to work on a project with a scientist-collaborator who uses their data in ongoing research. Introduces students to the rigors of science through the focus on data quality. Contains 21 references. (DDR)
