This circular tells how and where to collect insects; how to kill, preserve, and display them; and what equipment is needed. In addition, descriptions and illustrations of all twenty-eight orders of insects are given. This booklet is written mainly for 4-H Club members and high school students but will be useful to anyone who wishes to collect and…

This guide is designed to assist teachers in involving students in individual or small group laboratory investigative experiences in the life sciences. Each of the 22 experiments contains a prelab and postlab section for teachers and a detailed procedures section for students. (Author/CO)

Presents a laboratory exercise suitable for advanced placement biology or chemistry classes. Discusses the theoretical approach, preparation and standardization of reagents, and results. Emphasizes standard analytical procedure and chelometric titration. (CW)

Introduces a life science classroom activity for developing a knowledge of the human skeletal system, environmental poisoning, and bone growth pattern. Provides the situation, an organizational flow chart, relevant information materials, and directions. (YP)

A simple oxygen-collecting device (easily constructed from glass jars and a lid) can show bubbles released by water plants during photosynthesis. Suggestions are given for: (1) testing the collected gas; (2) using various carbon dioxide sources; and (3) measuring respiration. (DH)

Provides background information and student activities on plants of the desert, including various adaptations for life with limited water supplies. Each activity includes objective(s), recommended age level(s), subject area(s), list of materials needed, and procedures. A ready-to-copy student worksheet is included. (DH)

Outlines activities for each of eight science process skills (observing, using space/time relationships, classifying, using numbers, measuring, communicating, predicting, and inferring). Directions for the activities (all of which use sea shells) are included. (DH)

Described is a science activity for impressing upon students the complexity and the delicacy of interactions between organisms and the environment. (Author/SL)

This curriculum supplement aims to bring cutting-edge medical science and basic research discoveries from the laboratories of the National Institutes of Health (NIH) into classrooms. The supplement was designed to complement existing life science curricula at both the state and local levels and to be consistent with the National Science Education…

Ranger Rick's NatureScope is a creative education series dedicated to inspiring in children an understanding and appreciation of the natural world while developing the skills they will need to make responsible decisions about the environment. Contents are organized into the following sections: (1) "The Primates," including information…

Describes construction of a model that can demonstrate the activities of the human lungs. Among these are the effects of occluding the trachea and respiratory opening, the action of diaphragmatic and negative-pressure breathing and pressure changes. (SA)
