Here, we describe a laboratory experiment as part of an upper-level vertebrate physiology course for biology majors to investigate the physiological response of vertebrates to osmoregulatory challenges. The experiment involves measuring plasma osmolality and Na[superscript +] -K[superscript +] -ATPase activity in gill tissue of teleost fish…

What invertebrates make the best classroom pets? How should we care for each invertebrate? What type of inquiry activities could invertebrates support? How do elementary students respond to invertebrates? These were the questions investigated in The Critter Project, a three-week project that aimed to help students conquer their "critter jitters"…

The strong-inference protocol puts into action the important concepts in Platt's often-assigned, classic paper on the strong-inference method (10). Yet, perhaps because students are frequently performing experiments with known outcomes, the protocols they write as undergraduates are usually little more than step-by-step instructions for performing…

This investigative laboratory exercise uses the different relations between ambient temperature and metabolic rate in endotherms and ectotherms as a core concept to answer the following question: What thermoregulatory mode is employed by chicken embryos? Emphasis is placed on the physiological concepts that can be taught with this exercise,…

Secondary vocational-technical education programs in Mississippi are faced with many challenges resulting from sweeping educational reforms at the national and state levels. Schools and teachers are increasingly being held accountable for providing true learning activities to every student in the classroom. This accountability is measured through…

There is a group of terrestrial crustaceans, the isopods or sowbugs, that spend their lives in the cool, damp and dark microhabitats beneath rocks, decaying logs, and leaf litter. Although these animals are well adapted to exploit these moist niches, they are obligated to live where they do because of their need for moisture and high humidity to…

This booklet was prepared for use at workshops conducted by the Junior Academy of the New York Academy of Sciences and the New York Biology Teachers Association, as well as for use in the high school classroom and laboratory as an aid to both teachers and students. Its purpose is to help the beginning science research student in selecting and…

During the year the field force of the Bureau of Education in Alaska consisted of 5 superintendents, 1 assistant superintendent, 116 teachers, 9 physicians, and 11 nurses. Sixty-nine schools were maintained with an enrollment of 3,635. School buildings were erected at White Mountain, whither the Eskimos had migrated from Council; at Elim, within a…

Discovers little change concerning the use of animals in undergraduate psychology programs that do not offer a graduate degree. Few institutions have had any contact with animal rights activists and most chairpersons report that students generally favor the use of animals. Lists alternatives to animal use. (MJP)

Discusses who has the right to determine the use of animals in scientific research which includes medical experimentation and the toxicity testing of compounds, ranging from pesticides to cosmetics. Provides a list of questions for consideration and discussion. (RT)

This book of activities is designed to supplement a child's outdoor experiences and to encourage children to take a closer look at nature by creating temporary mini-habitats at home or in school. An introduction explains to students the concept of habitat and the responsibilities of keeping a mini-habitat. The remainder of the book contains…

This humane education activity book is written for children with the goal of helping them learn to respect animals and the environment. Not only does the guide provide information, introduce new ideas, and encourage critical thinking, it also lets young people know that they can help save animals and the environment. Children are invited to join…

Some preschool teachers have expressed concern regarding the lack of science instructional material for students age 2 through the preschool years. This videotape was developed to help fill this chasm in our educational system. It contains activities from students' everyday life such as eating, washing, and playing. These daily processes are then…

Suggests that persons concerned with personality formation might profit from an examination of the relationship between people and the domesticated animals they maintain. The Hare Indians in the Northwest Territories of Canada are discussed. (JMB)

The experiments reported here describe the relationships between the reflex-modulating effects of compounded stimuli and the effects of these stimuli when they act in isolation. (Author)
