This booklet is one of a series intended to provide explicit instructions for the collection of oceanographic data and samples at sea. The methods and procedures described have been used by the Scripps Institution of Oceanography and found reliable and up-to-date. Instructions are given for taking air samples on board ship to determine the…

The course in Applied Number is designed to be covered with the course in Pure Number (see SE 012 723 to 725). The aims of this course are stated to be: "the development of (1) comparison: as exemplified by measurement; (2) exploration of the environment; (3) skills: among these, estimation and computation; and (4) language: as a medium for…

This guide is a continuation of SE 012 726. Each section is organized under the same six headings: length, volume and capacity, weight, time, money, and spatial relations. A further section describes work on statistics and graphs which may be spread over the entire interval covered by this guide. A great number of activities are suggested, leading…
