This paper presents a simplified approach for the application of material efficiency metrics to linear and convergent synthesis plans encountered in organic synthesis courses. Computations are facilitated and automated using intuitively designed Microsoft Excel spreadsheets without invoking abstract mathematical formulas. The merits of this…

This guided inquiry activity was developed to help students "view" an equilibrium system from the particulate level and make connections to their macroscopic observations. Part I helps students observe a physical equilibrium system in which water is transferred between two larger containers. In Part II, students examine what happens to a chemical…

A practical exercise for developing a simple cost-effective solar ultraviolet radiation dosimeter is presented for use by middle school science students. Specifically, this exercise investigates a series of experiments utilising the historical blue print reaction, combining ammonium iron citrate and potassium hexacyanoferrate to develop an…

This is an instructional activity from a Crustal Evolution Project (CEEP) module which involves the student with evidence supporting continental drift and the past existance of Pangea. (MDR)

Describes some of the adaptations of science exercises found in the program Adapting Science Materials for the Blind. This program enables blind and other visually impaired pupils to participate in the activities of the Science Curriculum Improvement Study. (JR)

THIS TEACHING GUIDE IS DESIGNED FOR USE WITH AN ELEMENTARY SCIENCE STUDY UNIT "MICROGARDENING" IN WHICH SIMPLER AND LOWER FORMS OF PLANT LIFE ARE STUDIED THROUGH STUDENT ACTIVITIES INVOLVING MOLDS. THE MATERIALS HAVE BEEN CLASSROOM TESTED AND ARE SUGGESTED FOR MIDDLE AND UPPER ELEMENTARY GRADES. THE WORK HAS BEEN ORGANIZED IN FIVE AREAS…

Stresses the fact that science activities can be styled to the visually handicapped students' levels and degrees of independence. Use of extensive hands-on, concrete experiences as emphasized by Adapting Science Materials for the Blind (ASMB) is encouraged. (EB)

Presented is a series of activity cards developed in order to help children explore mapping ideas in a variety of ways. Children work with concrete materials such as blocks, puzzles, checkerboards, and three-dimensional graphs. Concepts covered include scale, the usefulness of symbols, and relationships. The games can be used with individuals,…

This article introduces the reader to Outdoor Biology Instructional Strategies (OBIS) materials. These materials are designed to teach children an understanding of basic ecological relationships. One teacher's use of OBIS materials with 7th graders is described. (MR)

A significant alternative to the traditional text-based approach to elementary science has been represented by the Science Curriculum Improvement Study (SCIS). Although the literature documents the process of the investigative approach, greater utilization of available programs and support from teachers are not evidenced. This investigation was…

There are ways in which elementary teachers in general and rural elementary teachers in particular can overcome inadequate science preparation and can upgrade the science program resources of their small schools. Parents and children should be involved in obtaining free and inexpensive science-related materials throughout the year. These can be…
