Space travel, even low Earth orbit, is probably several years away for most of us; however, students and teachers can research the edge of space by participating in the BalloonSat program. BalloonSat is an offshoot of the Space Grant Consortium's very successful RocketSat program. The Arkansas BalloonSat program consists of teacher-initiated…

To promote inquiry-based learning, the authors integrate the anatomy of a scientific journal article into their secondary science curriculum. In this article, they present three classroom activities used to teach students about the function and format of scientific journal articles. The first focuses on journal article figures, the second on…

In this theoretical article the authors discuss the role of technology tools in supporting students' argument construction within the context of middle and high school science. In the first part of the article they focus on the theoretical underpinnings for studying argumentation in school science and report on the difficulties associated with…

Describes the use of written and practical tests to evaluate achievement of some objectives of the Australian Science Education Project (ASEP). Achievement varied on the two tests. It is argued that good curriculum evaluation needs both types of assessment to accurately reflect student learning. (RH)

By concentrating radioactivity contained on luminous dials, a teacher can make a high reading source for classroom experiments on radiation. The preparation of the source and its uses are described. (DT)

Reports an attempt to infer from official statements and from course materials some of the assumptions and theoretical positions which underlie four high school physics courses: Nuffield Physics, ECCP's "The Man Made World," Harvard Project Physics, and PSSC Physics. (PEB)

This set of laboratory exercises in general science is an outgrowth of courses given by the author in methods of teaching secondary school sciences. Many of the exercises have enough material for more than one lesson and should be subdivided to suit teaching conditions. The emphasis placed in these lessons upon the interests of the individual, in…

MANY IDEAS TAUGHT IN ELEMENTARY PHYSICS TODAY ARE EITHER FALSE IN FACT OR ABSURD IN LOGIC, AND HAVING BEEN CARRIED ALONG BY TRADITIONAL PRACTICE, THESE ERRORS AND MISCONCEPTIONS CONTINUE TO BE PROMULGATED. MANY MISCONCEPTIONS AND ERRORS COMMONLY FOUND IN CURRENT TEXTBOOKS ARE EXAMINED. AREAS DEALT WITH ARE (1) FORCES, (2) GRAVITATION, (3) ENERGY,…

The major portion of this publication is devoted to the presentation of 20 chemistry experiments dealing with corrosion of metals. The experiments are intended for high school level students or for chemistry teachers for demonstration purposes. Diagrams and illustrations accompany the written directions. Also included in this publication are…

A short description of the availability of Harvard Project Physics course components is given as is a discussion of the growth of the use of Project Physics in schools, including some enrollment data and survey results. Locations of the 1970 and 1971 Summer Institutes are listed. Adaptations of Project Physics course outside the United States are…

The syllabus for a general biology course (which may be used for one Group III credit as an elective toward a New York State Regents High School Diploma) contains five major units. These units - Life Functions, Systems of the Human Body, Continuation of Life, The Green Plants, and Classification and Evolution - are designed to "involve the…

Includes latest theory concerning the flight of the returning type of boomerang. Some comparisons in aerodynamics are made between returning and non-returning boomerangs. (CS)

Proposes a model that implies that enrollments in science classes will increase if the grade penalty in science subjects is less severe. Students' decisions are based on rough comparisons between their grades in other subjects and early science courses. Student records from 27 schools were analyzed for correlations between many variables. Results…
