This packet contains three science learning activities that can be used in agricultural education courses. The activities cover these topics: (1) determining the effects of soil particle size on capillary action; (2) measuring levels of eroded soil particles in streams; and (3) determining the effects of soil cover and texture on surface erosion.…

There is a natural tension between experimentally designed studies and case studies, which differ in that they are not concerned with the interaction of variables in the quantitative and statistical sense. This paper describes a study that was not experimentally designed, but its major findings were generalizable to the overall population of…

This book is designed to be a guide for a hands-on science experience for students in grades 3 through 6. Over 200 students can participate at the same time, moving from one station to another. The activities have been selected to encourage experimentation, creativity, higher-order thinking and fun with science. All activities use multi-modality…

Microcomputer-based laboratories (MBLs) are believed to have significant potential for improving laboratory experiences in science classrooms. A study funded through a grant project called STEPS to Better Science sought to broaden the knowledge base by examining MBL use by teachers and students in a variety of science classrooms in six high…

Problems with conducting randomized field experiments in education are explored. Focus is on problems encountered while evaluating a group of dropout prevention projects. Project planners were asked to manipulate the subject eligibility criteria until they identified as eligible three to four times as many students as they could serve. They were…

Designed to alleviate the confusion caused by the existence of a multiplicity of approaches to writing research, the four parts of this book present explicit discussions of research principles and methods used by researchers actively working within a variety of disciplines. The two chapters in Part 1 describe very broad views of the entire…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide is a four-part unit…

A survey of 102 New Jersey secondary school science teachers, department chairpersons, and supervisors concerning their laboratory accident-rate was conducted during the 1981-82 school year. Results indicate that accidents occur on a weekly basis even among a sample of experienced teachers who were interested in safety. The number of accidents…

This unit, developed by the Third World Science Project, is designed to add a multicultural element to existing science syllabi (for students aged 11-16) in the United Kingdom. The project seeks to develop an appreciation of the: boundless fascination of the natural world; knowledge, skills, and expertise possessed by men/women everywhere;…

This document is intended as a guide for both experienced and inexperienced teachers of Regents Biology in New York State. It presents a collection of demonstrations, activities, and strategies designed to enrich the teaching of that course. The guide includes seven units of study. Units are focused on unity and diversity among living things,…

This document reviews a collection of activities conducted by the Department of Physics at Virginia Commonwealth University to excite young people about physics so that they will be more likely to consider physics as a career. The Society of Physics Students performs demonstrations of physics experiments for Virginia high school physics classes…

Designed to arouse interest in students about animals, this document was developed to provide teachers with a variety of information and teaching activities. The booklet is intended to enable students to become knowledgeable about science concepts relating to animals without the use of expensive equipment. The teaching activities deal with: (1)…

Designed to supplement a basic life science or biology program, this document provides teachers with experiential learning activities dealing with the human body. The learning activities vary in the length of time needed for their completion, and require a minimum of equipment and materials. The activities focus on: (1) the human skeleton; (2)…

Based on the idea that active participation stimulates the processes by which learning takes place, this document provides teachers and students with a variety of information and learning activities dealing with chemistry. Basic concepts about chemistry are presented through the use of laboratory experiments, demonstrations, worksheet exercises…
