Describes a method suitable for quantitative studies of plant water status conducted by high school or college students and the calculation of the relative water content (RWC) of a plant. Materials, methods, procedures, and results are discussed, with sample data figures provided. (CS)

Using the hydrolysis of crystal violet dye by sodium hydroxide as an example, the theory, apparatus, and procedure for a laboratory demonstration of tubular reactor behavior are described. The reaction presented can occur at room temperature and features a color change to reinforce measured results. (WB)

Notes how laboratory experiences can help elementary school social studies pupils understand concepts such as cultural awareness, career education, advertising techniques, map and globe skills, music, transportation, and landforms. For each concept, information is presented on objectives, activities within a laboratory setting, and evaluation…

Discusses the limitations, problems, and inefficiencies with the language lab systems and some of the corrections that should be made to alleviate these problems. The problem is generally in the area of monitoring of more than one student at the same time and of correcting students. (PJM)

Compares two methods of laboratory instruction: an instructor-led conventional lecture-discussion approach and an experimental team learning approach. Subjects were assigned to groups of four or five in experimental classes. Students in control classes worked individually. While differences in group means did occur, results were not significant.…

Presents a case study of the development of a faculty media production laboratory by Michigan State University's media center, describing funding, facilities, promotion, utilization, and future plans. (CMV)

Describes a way to construct from aluminum foil and a tin can a detector of ionizing radiation in the environment. (Author/SA)

Descriptions of four gifted programs are offered in articles titled "Career Education for Gifted Students in Illinois" (J. Ellis and B. Ford); "Interage Program for Critical Thinking" (H. Masterson); "Talcott Mountain Science Center" (D. LaSalle); and "Project L.O.G.I.C.--Nurturing the Mathematically Gifted" (W. Foley and B. Spack). (SBH)

Describes the advantages and disadvantages of required v drop-in tutoring at a writing lab and advises the training of peer tutors through peer criticism in a credit-bearing course. (DD)

Suggests that differential rearing conditions may cause significant reversals in sex-related ability and behavior (maze learning and exploration), and may significantly affect perceptual sensitivity. (RL)

Authors provide guidelines for a program utilizing learning stations designed to motivate, stimulate, and guide affective and cognitive education at higher levels of thinking for academically gifted students. This approach to enrichment is defined, and the role of the teacher as facilitator is considered. (SBH)

Describes an experiment on heat that utilizes only a styrofoam cup of coffee and a soda straw thermometer. (BT)

Describes a simple method of measuring the refractive index of a liquid using a paper cup, a liquid, a pencil, and a ruler. Uses the ratio between the actual depth and the apparent depth of the cup to calculate the refractive index. (GA)

Reports and summarizes some of the findings of a conference, held in Oxford in July 1978, to discuss the role of the laboratory in physics education. (GA)

This laboratory experiment was designed for undergraduate students. It demonstrates the use of simplex optimization in a simple and straightforward manner. (BB)
