This undergraduate organic laboratory exercise involves the sulfuric acid-catalyzed conversion of waste vegetable oil into biodiesel. The acid-catalyzed method, although inherently slower than the base-catalyzed methods, does not suffer from the loss of product or the creation of emulsion producing soap that plagues the base-catalyzed methods when…

For various reasons, students do not have access to laboratory facilities and yet need courses in the laboratory sciences such as chemistry. This paper describes "Outreach Chemistry," a course developed to provide a chemistry laboratory experience for students attending schools that lack science laboratories. Designed for off-campus students whose…

Discusses instructional strategies and activities designed to help students learn to recognize patterns and to create models to explain patterns. These include laboratory investigations and an exercise in which students are challenged to find the model used for the classroom seating arrangement. (JN)

How do you get a fourth-grader excited about history? How do you even begin to persuade high school students that mathematical functions are relevant to their everyday lives? In this volume, practical questions that confront every classroom teacher are addressed using the latest exciting research on cognition, teaching, and learning. How Students…

Provided is a model to depict how the development of process skills can be systematically achieved and in turn determine the students' achievement in science practicals. Modified laboratory instruction is compared with conventional laboratory instruction. The results of field testing on 164 ninth grade subjects are described. (MVL)

Addresses whether or not science laboratory activities should become a thing of the past. Discusses the impact of the curriculum reforms of the 1960s and 1970s, physical restraints which cause teacher overload, rationale, and objectives of laboratory work. (RT)

This guide was developed with the intention of helping teachers and school site administrators in California review the elementary science curriculum and compare it to an idealized model that is presented in the document. Part I of the guide provides a summary of a number of characteristics considered to be important to a strong elementary science…

This publication provides information and activities for identifying objects using the five senses and process skills including observing, classifying, collecting and interpreting data, inferring, and predicting. Lessons 1 through 3 deal with the identification of an unknown substance and the physical properties of powders. Lessons 4 through 6 are…

The Prime Minister's Committee on Natural Science in Education in Great Britain reported in 1918 that "...in many schools more time is spent in laboratory work than the results obtained can justify." Seventy years later this conclusion can often still be drawn. This is particularly a problem in open distance education where laboratory practicals,…
