The "Children's Science Curiosity Scale" is composed of 30 Likert-like items which examine various curiosity factors in the context of science learning. Internal consistency, test-retest reliabilities, and validity of the instrument were investigated. Sex differences using the instrument were also investigated. (JN)

Basic concepts are often barriers to acquiring easy insight and satisfying understanding in a discipline. The most difficult task in the teaching of science is the recognition of these critical barriers to the student's thinking process. To make the unobvious less so is the responsibility of the teacher. (BC)

Discusses inquiry and discovery methods in elementary school science education; emphasizes the importance of teachers knowing whether they are using the inquiry approach and to what extent. Presents a chart listing the steps involved in problem solving, indicating whether a step is teacher- or student-controlled. (BC)

Describes a soap bubble motor, house insulation models, using hot-water bottles as heat sources, solar mobile, surface tension boat, evaporative cooling experiments, six activities on heat, and a magic trick based on friction. Also discusses using the Cambion Electronics Kit to introduce junior high students to the subject. (JM)

Experiments which illustrate the effect of humidity on human hair and on paper are described. Also described are two ways to make a hygrometer. These methods were found in a series of British television programs (also available in the United States). Comments on the programs are included. (JN)

Suggested are a few topics or techniques which should not be presented in planetarium astronomy until appropriate levels of potential comprehension are reached. (EB)

Interviews conducted with a group of Lebanese children showed that they give physical rather than animistic interpretations to natural phenomena such as rain, clouds, and falling bodies. (MLH)

Based on the numerous ways physical constants are used daily. A knowledge of the meaning of a constant is deemed necessary. Various studies done by elementary school children are presented. (EB)

Reported are the results of an evaluation of the Nuffield Combined Science projects utilized in English schools for biology, chemistry and physics instruction. Evaluations by 18 teachers and 420 students indicate that the course is effective in teaching expected skills. (SL)
