The purpose of this study is to investigate the elementary pre-service teachers' views about "the purpose of science experiments". For the study, the views about the purposes of scientists' experiments and school science experiments were surveyed from 227 pre-service teachers. And the responses were analyzed based on their gender, intensive majors and school science test scores. The main results of the study are as follows. First, in relation to the purpose of scientists' experiments, the pre-service teachers considered internal values of doing experiments were more worthy than the external values of it. In particular, the pre-service teachers responded that the most important purpose of the science experiments is 'to get the evidences for the theories and arguments'. On the other hand, the views from the women and social studies major pre-service teachers were more diverse than those of the man and science major pre-service teachers. Second, in relation to the purpose of school science experiments, the pre-service teachers excessively considered that the internal values of school science experiments were more worthy than the external values. In particular, only few pre-service teachers were aware of social and personal aspects of the experiments, though they considered well that the experiments are useful tools for the school science study. Third, there were quite different aspects of pre-service teachers' views between the purposes of scientists' experiments and school science experiments. For example, the views about the scientist's experiments were relatively broad concerning the nature of scientific experiments, but the school science experiments were just regarded as an educational tool for the science study. Based on the results from the study, some science educational implication were discussed.

Experiment is recognized as an important part in science and science education. Scientists do experiments for verifying or refuting theory and they take many forms to do experiments. One of the central goals of science education is to improve inquiry ability. So we have taken for granted that students engage in authentic inquiry and experiment which scientists carry out to research. But it is not always positive about discussions and opinions what school experiment and its role is in learning science and understanding about science. There is certainly a gap between experiments which scientists and students do even though there is a theoretical basis of school science experiment. In this study, we discussed how scientific inquiry and school inquiry are different, and what it means to use instrument in school science experiment. And as a case, we analyzed chemistry experiments in science textbook and manipulation level of instruments which were handled in chemistry experiments, we shed light on the meanings of experiments and instruments in school science inquiry based on the result of experiments and instruments analysis.

This study investigated the elementary school students' perception of the "purpose of scientists' experiments" and discovered what roles teachers can take to provide guidance. The study subjects were 193 elementary school students (96 boys and 97 girls) in a school located in Gyeonggi-do. The responses were analyzed through categorization based on their gender, science test score at school, and understanding of the purposes of scientific experiments based on students' choice of science-related future careers. The results of this study were as follows. In relation to the purpose of science experiments, the elementary school students considered intrinsic values of doing experiments more valuable than their extrinsic values. Next, 34.2% of the students answered that scientists do science experiment 'to find a new fact' and 26.9% of the students answered 'to make life convenient.' The results showed that girls responded 'social usefulness' more frequently than boys. Considering the achievement levels, it was found that high level students replied 'to make life convenient' more frequently than middle and low level students on why scientists do science experiments. Students who want to have a science-related career had varied ideas about it.

The object of this study is to investigate the views of scientifically gifted children about the purpose of scientists' experiments and school science experiments. The children's views were examined using a open-ended questionnaire survey. And then the responses from the children were analyzed with categorization. The results from the study are as follows: First, the children's views about the purpose of scientists' experiments and school science experiments were classified to 2 top-level, 5 mid-level and 21 sub-level categories. Second, it was found that the children considered internal values of doing experiments are more worthy than the social and personal usefulness of the experiments. Third, the gifted children mentioned most frequently that the purposes of the scientist experiment is 'to get the evidences for their theory and argument which is unusual in the regular children's views. Also the discovery of new phenomena and materials, and the generation of new theories and ideas were mentioned as purposes of the scientist experiments. Fourth, the students frequently stated that school science experiments support effective learning of science subject enhancing subject interests and better explanation/understanding. Fifth, relatively many students thought that the purposes of school science experiments are different with those of scientist experiments. Based on the results from the study, some educational suggestions are discussed.

We developed problem-solving type inquiry learning programs reflecting scientists' research process and analyzed the activities of science-gifted high school students, and the understanding and the effects of the programs after implementation in class. For this study, twelve science-gifted students in the 10th grade participated in the program, which consisted of three different modules - making a cycloidal pendulum, surface growth, and synchronization using metronomes. Diet Cola Test (DCT) was used to find out the effect on the improvement of the ability to design experiments by comparing pre/post scores, with a survey and an interview being conducted after the class. Each module consisted of a series of processes such as questioning the phenomenon scientifically, designing experiments to find solutions, and doing activities to solve the problems. These enable students to experience problem-solving type research process through the program class. According to this analysis, most students were likely to understand the characteristics of problem-solving type inquiry learning programs reflecting the scientists' research process. According to the students, there are some differences between this program class and existing school class. The differences are: 'explaining phenomenon scientifically,' 'designing experiments for themselves,' and 'repeating the experiments several times.' During the class students have to think continuously, design several experiments, and carry them out to solve the problems they found at first. Then finally, they were able to solve the problems. While repeating this kind of activities they have been able to experience the scientists' research process. Also, they showed a positive attitude toward the scientists' research by understanding problem-solving type research process. These problem-solving type inquiry learning programs seem to have positive effects on students in designing experiments and offering the opportunity for critical argumentation on the causes of the phenomena. The results of comparing pre/post scores for DCT revealed that almost every student has improved his/her ability to design experiments. Students who were accustomed to following teacher's instructions have had difficulty in designing the experiments for themselves at the beginning of the class, but gradually, they become used to doing it through the class and finally were able to do it systematically.

The purpose of this qualitative case study was to investigate the 'structure' of an elementary school teacher's practical knowledge concerning science experiment lessons. A female elementary teacher in the early career years participated in the study, and video recordings of her science experiment lessons as well as audio-taped interviews with her were analyzed by means of Elbaz's framework. The teacher expressed six images of science experiment lessons: 'Science is difficult', 'Experiments are dangerous', 'Experiments are accurate', 'A science experiment takes a long time', 'Science experiments are interesting', and 'Children are little scientists.' These images were supported by several principles and rules, most of which were clearly described. Among the images, principles, and rules, there were complex relationships with some working in synergy and some conflicting. In case of the image 'Children are little scientists', its subordinate principles and rules were not fully realized in the classroom. Implications for science teaching reform and science education research were discussed.

We analyzed $3^{rd}$ graders' images of scientists and science learning students. We chose $3^{rd}$ graders because this is the time when children first encounter formal science learning opportunities. Draw-A-Scientist-Test (DAST) and the revised Draw-A-Scientist-Test Checklist (DAST-C) were used to analyze students' images of scientists, whereas Drawing-A-Science-Learner- and a checklist were used to analyze students' images of science learning students. We found that $3^{rd}$ graders showed common features of scientists who wore laboratory coats but not wearing glasses, goggles or masks and smiling. While most boys drew a male scientist, about a half of girls drew female scientists. Old and weird looking images of scientists that were typically known in other literatures were not found in this study. Science learning students were not wearing lab coasts, glasses, goggles, nor masks. Most of those students were conducting chemistry related experiments, which seemed to be influenced by the $3^{rd}$ grade's science curriculum. We also found relationships among components of images of scientists and science learning students. Although $3^{rd}$ graders' images of scientists and science learning students showed common features, this typical image was not the same as the previous studies have reported. This implies that the images of scientists and science learning students have not yet fixed by $3^{rd}$ grade. Thus, this seems to be a critical time when children start developing images of scientists. Children's direct experiences in the science classroom along with environmental factors such as media exposures can influence their formation of images of scientists and science learning students.

The first part of the paper concerneded about the history, meaning and function of the aromatherapy. And the next part is about the therapeutic effects by the inhalation fragrance or permeation of essential oil through the skin, which are all based on the recent experiments. Today, the aromatherapy is public interest in the world. And also many cosmetic companies have been making use of the aromatherapy as the concept of their new products. But any Korean manufacturer has not taken the application of the aromatherapy in the cosmetics. Why we can't do this. Therfore I try to explain this problem at the last part of the paper and also introduce some Aromatherapy products.

It is by the mad scientists that the ontological and epistemological turn was made in that scientific era. They achieved a scientific revolution although they were regarded as eccentric, comic, unsound, and evil ones in the dark and dismal labs. Likewise, a scientist who would like to create an anomaly, something novel and abnormal, tended to be considered mad and treated as such either because of his scientific theory which differed from those of other scientists or because his obstinate methodology was often blamed for its immorality and profaneness. Despite the fanciful purpose and the anomalous way in which the mad scientists did their experiments, these were attempts to explore new scientific terrain and find something new or unexpected, which often raised controversies between the old paradigm and the new one. As Thomas Kuhn manifests, subsequently, "an older paradigm is replaced in whole or in part by an incompatible new one" and then, "there must be a conflict between the paradigm that discloses anomaly and the one that later renders the anomaly lawlike." In that sense, Frankenstein's, Jekyll's, and Moreau's eerie challenges can be interpreted as efforts to achieve the ambitious goal of solving the scientific mysteries of the world in such unfavorable environmental conditions as specified in the three novels.

In this study, we developed a model for analyzing scientists' creative thinking processes, and analyzed Archimedes' thinking process in solving the golden crown problem. As results show, scientists' complex problem solving processes could be represented as a repeating circular model, and the fusion of processes of diverse thinking required for scientists' creativity could be analyzed from the case. Also in this study, we represented the role of experiments in scientists' creative discovery, and investigated the reasons for the difference between the viewpoints of textbooks and historic facts. We found the importance of abductive reasoning and advance knowledge in creative thinking. Archimedes solved the golden crown problem creatively by crossing the scientific thought of dynamics and the daily thought of baths. In this process, abductive reasoning and advance knowledge played an important role. Besides Archimedes' case, if we would reconstruct the creative discovery processes of diverse scientists' in textbooks, students could raise their creative thinking ability by experiencing these processes as educational steps.
