Even though photosynthesis is an obligatory part of the science curriculum, research has shown that students often have a poor understanding of it. The authors advocate that classroom coverage of the topic of photosynthesis should include not only its biochemical properties but also the role of photosynthesis or photosynthetic organisms in matter…

Many teachers and other educators have expressed a concern regarding the lack of student interest in many of the traditional science courses. Concerns have also been expressed by teachers of their dissatisfaction with much of the lecture material and the laboratory exercises in some science classes. To help rectify this problem a collaborative…

This teacher's edition of "A Manual of Experiments in Elementary Science" includes full directions and explanations regarding all manipulation, answers to all the questions in the "Student's Manual," diagrams, and additional hints and suggestions. The work covers elementary science experiment outlines adapted for use with…

Presented is an activity in which students use a microscope to do a forensic hair comparative study and a medullary classification. Mounting methods, medulla types, hair photographs, and activities are described. (DS)

Focuses on the curriculum movement. Discusses the educational conditions under which new courses would be developed. Explains the differences between the new science courses and traditional courses. First published in 1962. (YDS)

Describes an experiment designed to measure absolute zero using Charles' Law without the use of mercury. Provides the procedure and details of the apparatus and includes experimental results obtained using the apparatus. (DDR)

Describes a course for science education majors that explores the uses of computer-interfaced experiments in a variety of interesting activities. Several examples of biology experiments are given. (ZWH)

A science and social studies unit developed around rosin is described. Students develop an understanding of the processing of raw material from a plant source into a commercial product and how to protect wood from weathering by preparing, testing, and evaluating varnish and shellac for their wood protective qualities. (Author/DS)

Discusses distillation of liquid mixtures with the emphasis on experimental work. A number of experiments, intended for chemistry secondary school teachers in the United Kingdom, are included. (HM)

Described is a praparium, a completely sealed and self-contained living aquarium. Steps on how to set up the aquarium, cautions, and a list of suggested aquarium plants and fish are included. (DS)

Describes the chemical reactions and compounds involved in making a cake. A protein coagulation and gas expansion laboratory activity is included in which the students bake a cake and eat it. (DS)

Reviews research related to laboratory work and makes recommendations for the classroom on how to make labs more meaningful. Argues that pre- and post-laboratory discussions containing theory behind the lab and purposes of the lab are essential for new understanding. (DDR)

Suggests that because controlled experiments are used extensively by professional ecologists to solve both theoretical and applied problems, experimentation should be a key component of secondary school ecology curricula. Describes five teaching principles to guide secondary school biology teachers in providing a more realistic view of the…

Describes an experiment to identify lactose and estimate the concentration of lactose in a sample of milk. Gives a background of the investigation. Details the experimental method, results and calculations. Discusses the implications of the experiment to students. Suggests further experiments using the same technique used in…

This book contains the teacher's guide of the Environmental Inquiry curriculum series developed at Cornell University. It is designed to teach learning skills for investigating the behaviors of non-native and native species and demonstrate how to apply scientific knowledge to solve real-life problems. This book focuses on strange intruders…
