Describes an in-depth, comprehensive method that enables students to understand the basic concepts of visual perception. (JRH)

Compares a broad cross-section of high school biology laboratory manuals with respect to several standard features as well as the degree to which they engage students in scientific inquiry. Discusses comparisons with respect to topics contained in the manuals, types of activities, lab exercises, and features of activities. (JRH)

Describes historic aspects of color or coloring. Presents activities involving spectral colors identified by Sir Isaac Newton and others involving dyes and dyeing. (MKR)

Describes having a pot-bellied pig in a classroom. Students learned how to care for the pig and train it. Describes other animals in the classroom and the class putting on shows for other students. (PR)

Presents a series of investigations focusing on the biodegradable packing materials ("peanuts"), which provide a method for exploring science through experimentation. These activities can help fourth through sixth graders sharpen their critical thinking and science process skills. (PR)

Describes a project by secondary-level students of constructing a rain forest in a 14-by-14-by-8 meter space in a shopping mall. (PR)

Describes the effects when a clear toothbrush is used as total internally reflecting light pipe when attached to a laser. Several explanations are given describing the nonuniformity of the transmitted light resulting from surface and internal irregularities found in the toothbrush. (MVL)

This activity was created to address a lack of problem-solving activities for elementary children. A "monorail" activity from the Evening Science Program for K-3 Students and Parents program is presented to illustrate the problem-solving format. Designed for performance at stations by groups of two students. (LZ)

Presents a Project WET water education activity. Students rank and compare different uses of water in order of their importance. The class develops a "Water Index," an indication of the group's feelings and values about water and its uses. (LZ)

Presents 17 classroom activities with an environmental theme. Activities are divided by grade level (grades K-2, 3-5, 6-8, and 9-12) and by subject matter (science, social studies, language arts, mathematics, and fine arts). Contains 15 suggestions for celebrating Earth Day. (LZ)

Drawing from current models, research, and science and mathematics education reform documents, this article first defines and/or delimits three broad domains of education: integrated school science and mathematics, assessment, and technology. A list of characteristics is derived, and two integrated school science and mathematics activities are…

Describes activities that will help students understand how car seat belts work, the limited reaction time available to passengers in an automobile accident, and the force of impact in a car collision. These activities will provide students with hands-on experiences that demonstrate the importance of always wearing seat belts while in an…

Describes the involvement of students in the construction of an inexpensive wooden balance to aid in their understanding of mass. (ZWH)

Discusses the effects of blowing bubbles in extremely cold weather. Describes the freezing conditions of the bubbles and some physical properties. Suggests using the activity with all ages of students. (MVL)

Provides a motion activity where a student walker is timed as he passes various students along a set course. The motion of the walker changes with each trip. The findings are then graphed and the results discussed. (MVL)
