In this study a few laboratory teaching materials have been developed to be available for the effective performance of experiments and practices- a heart of inquiry learning-as a continuance of 'A study on the Development of Laboratory Teaching Materials for Middle School Science Course I' The present condition of science education has been investigated by means of questionaires, interviews and literature, the results of the present condition and problems in junior high schools are as follows: 1. The hours for science classes are considerably little for the teaching contents of science textbooks. 2. The level of teaching is beyond the student's capability in terms of their experience and intellectual development. 3. Science teachers are overburdened with much tasks, and laboratories and laboratory facilities are too insufficient and furthermore teaching is mainly conducted on the lecture method as a preperation for various entrance exams. 4. Teachers' eagerness and desirable attitude for teaching are required. In this study, materials for every branch of science have been developed to be available for the effective performance of experiments and practices through inquiries. The materials developed in this study are as follows: 1. In physics, measure apparatus of extremely small masses, length, and very little time intervals are developed. 2. In chemistry, new methods for gas generating apparatus and materials. are developed. 3. In biology, the size of quadrate and the method to decide the time in facilitating for the purpose of survey of botany community are introduced. The results of the investigation of natural enemy on Hyphantria cunea, and the study on collecting, breeding of Planaria are also shown. 4. In earth science, the laboratory teaching materials are developed for observing continuous spectrum and line spectrum. Putting the above results of study together, the suggestions are made to the effect as follows: 1. The quantity of learning should be reduced and the levels lowered in the new textbooks. 2. The development and distribution of various teaching materials(film, T,P., cassettes film, supplementary, textbook, program teaching material, individual learning material) is required. 3. The experimental instruments should be timely manufactured and distributed on the basis of effective administrative support to ensure their solidity and accuracy. 4. The concrete design to eliminate the teacher's burden should be contrived and the system for senion teachers in charge of science teaching in secondary schools, should be improved. 5. Teacher's research activities should be encouraged through various research institutes(Institute of science education , graduate school of education and the other research institutes.) 6. The disposition of laboratory assistant should be considered. 7. More positive supports from other societies relevant with education are much expected to be made.
