Suggests a simple technique for collecting and observing human hair roots to compare structure, function, and variation. Students extract their own hair samples and view them using a 40-power microscope objective. Differences between active/inactive phases of hair growth are readily observed. (The activity can be adapted for younger students.) (DH)

Objectives, materials needed, procedures, discussion questions, and follow-up activities are provided for five experiments. They include (1) testing for sugars; (2) comparing sugar to artificial sweeteners; (3) chewing gum scientifically; (4) soap making; and (5) making toothpaste. (JN)

A five-week course for fourth- and fifth-grade students (titled "Chemistry for Kids") was developed. Each class session consisted of a brief lecture, a demonstration, and one or more experiments. An outline of concepts fostered, instructional strategies, and procedures used is provided. (JN)

Six major concepts of science are illustrated through the use of simple, easily equipped hands-on activities. Included in each activity are a list of materials, procedures, questions for students, and suggested discussion. Aquatic acoustics are highlighted. (CW)
