Individuals who grow in this context can be good citizens who knows the requirements of the age, questioning, investigating and able to establish a connection with daily life. In addition, while teaching science, the aim is not only to teach the concepts but also educate the students to solve the problems they face with throught their life, in scientific ways, and to manage to look through the scientisits' eyes to the phenomena and the World. By providing these skills, it is mportant to know teachers' perceptions of the applications of these skills. Literature show that there are limited valid and reliable instruments which evaluate teachers' scientific process who teach science. From this point, in this study, the scale for teachers' perceptions of the application of scientific process skills developed by Rambuda and Fraser (2004) was adapted. The adaptation process was performed in three different universities. The sample consisted of preservice teachers in three educational faculties. The scale consisted of 22 items using 4 point Likert Scale. The scale was applied to 686 preservice teachers in teacher training programme during 2014-2015 academic year. To test the language equivalance, English and Turkish versions of the scale was applied to 58 students in English teacher training programme and positive and significant correlations were identified. To determine construct validity of the scale, exploratory and confirmatory factor analysis were conducted. Results of exploratory factor analysis showed that the scale consisted of 2 dimensions: Basic science process skills and integrated science process skills. The valus of factor loadings varied within the range of ,46-,78. The inner consistency coefficient for reliability was calculated to be ,91. The ciriterian validity results showed that the scale is suitable for the purpos. The result of confirmatory factor analysis showed that indices were found at an acceptable level and determined that the scale was relevant to the real data. The findings of the study identified that the teachers' perceptions of the applications of scientific process skills scale is valid and reliable assessment tool.

In order to overcome these difficulties, different teaching methods are tried and it is attempted to attain success. Educators usually study the question of " how can we provide an easier and more permanent teaching? " As a solution to this problem they agree that activities which draw the attention of the students and which the students get pleased and entertained while doing enable the effective learning in teaching the concepts of science. In this regard project-based learning is one of the effective methods. However, it is not often preferred by the teachers due to the problems in the supply of materials and being long-term activities. Thus, primarily students were made to experience a scientific process by using the processes of project-based learning and a method which had an easy and cheap material supply was used in the study. By using the materials which everyone could buy easily and in a cheap price, senior students of Education Faculty were made to do edible projects. For these projects, students were divided into groups of two people and each group modelled a concept of science that they chose themselves by using edible materials such as sugar, cake, chocolate, pasta. In total, 15 groups of two people developed 26 different projects. These projects were mostly made by using the concepts of science such as cell, DNA, RNA, mitosis and meiosis, brain, atomic models, periodical table, planets, solar system and earth's crust. These projects were later exhibited and they were introduced and presented to the other students in the Faculty. It has been observed that the students' awareness for the concepts of science increased while the projects were being done and exhibited. It has been observed that this presentation drew attention as students tasted the models and shared them with the other students. It is quite important that these projects are introduced and published in order to popularise the use of such projects in all levels of teaching. For this purpose, it is aimed to discuss how these projects are going to be used in science teaching and the contribution of such projects to science teaching by explaining how these twenty six projects were done.
