A technique for studying various properties of soap bubbles subjected to deformation, accompanied by some representative experiments to illustrate the versatility of the method, is presented. The measurement of the change of force that occurs when a bubble is stretched is calculated. (KR)

Activities that highlight the unknown and the fact that successful science is produced as much by contradictions as by confirmations are described. The activities are intended to help students begin expressing and channeling their individual curiosity. The topics include ecosystems and energy. (KR)

Activities designed around packaged items such as toothpicks are used to teach students to identify variables, gather and analyze data, use statistics, and draw conclusions based on evidence. A computer database used to keep track of data is described. Curriculum extensions in writing, math, and art are included. (KR)

Suggests ways parents can help steer their children toward the field of science, noting the current decrease in the proportion of students in science and engineering. Some of the ideas are to take children to museums, watch science specials on television, and buy toys and tools that teach. (SM)

This article describes a program providing a school district's most able high school students with advanced laboratory experience through access to facilities in an area university. Subjects studied include electronics, nutrition, and microbiology. Professors working with the students are interviewed and other experts comment on this approach. (PB)

Discussed is the purpose of role playing in the classroom. Suggestions for preparing for role playing are enumerated. The advantages and rationale for role playing in the science classroom are stressed. (CW)

The use of an olfactory acid-base indicator in titrations for visually impaired students is discussed. Potential olfactory indicators include eugenol, thymol, vanillin, and thiophenol. Titrations performed with each indicator with eugenol proved to be successful. (KR)

Different types of spiders, their ranges and habits are discussed. Activities associated with the study of spiders are suggested. Four references are listed which may be of interest to beginners. (CW)

Presents several electricity activities for developing student's science process skills of observation and inference. (PR)

Describes problems with teaching embryology in the traditional manner. Presents a new approach where students prepare presentations, questions, and discussion topics. During laboratory periods, students conducted their own long-term research projects. (PR)

Describes an activity appropriate for college or high school students where they make hypotheses about prearranged patterns in a deck of playing cards. (PR)

Describes a series of lessons on spiders that encompasses the varied interests and learning styles of young children. (PR)

Presents activities and techniques for introducing students to the concepts of digestion, chemical reactions, and enzymes. (PR)

Presents an activity where students investigate whether crackers contain sugar (Benedict's test solution) and starch (Lugol test solution) before and after being chewed. (PR)

Describes three exercises that will assist advanced high school and undergraduate students in understanding: (1) the concepts of randomness; (2) the importance of randomly assigning subjects to treatments; and (3) the statistical concepts of degrees of freedom. (ZWH)
