Presents an investigative sequence of experiments addressed to the topic of photosynthesis. (BR)

Describes how astrophysics can be a do-it-yourself project within a school boy's budget and background, by giving detailed instruction on equipment construction. In addition, this article describes many experiments to undertake, with the equipment, such as determining color temperature, star spectra, chemical composition and others. (BR)

Describes a set of experiments for the catalytic oxidation of alkenes to aldehydes and ketones which can be carried out in a test tube by the student. (BR)

This unit is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit, which consists of two levels, focuses on the elements and compounds of Group IV (halogens) of the periodic table. Level one deals with the physical and chemical properties of the individual elements. Level two considers…

This guide, the second in a series of three, provides the intermediate science student and teacher an opportunity to review selected science concepts and processes through activities which emphasize the applicability of scientific knowledge in the professional world. The guide is divided into three components. The first component helps students…

Science experiment books which typically incorporate relatively large numbers of questions can be an especially important resource for children who are learning scientific processes. These processes include observing, communicating, hypothesizing, experimenting, measuring, classifying, generalizing, and predicting. An analysis of questions in…

This 12-chapter book examines different phenomena as viewed by those trained in physics. These views (or vistas) are promulgated to demonstrate that the infinite variety of things seen in the material world can be reduced to a handful of general laws and to share with the public the richness of the scientist's world view. The phenomena examined…

This procedure, using polystyrene spheres of specified diameter, renders the Millikan oil drop experiment more accurate than the conventional procedure of the polystyrene spheres, eliminates size estimation error, and removes the guesswork involved in assigning proper index integers to the observed charges.

Developed for mathematics-shy high school chemistry students, this laboratory manual is suitable for use with any chemistry textbook. Seventy-three experiments, based on a theme of change, are grouped into 5 general areas: (1) 9 experiments focusing on skills needed in observing reality; (2) 19 experiments interpreting how reality changes,…
