Paper Title
The Effects Of Science Experimental Activities For Early Childhood On Life Cycle To Development Science Process Skills Of Early Childhood Student Teachers

Abstract
The objectives of this research were to study and compare the science process skills of early childhood student teachers before and after using science experimental activities for early childhood on life cycle. The sample used in this research were 4th year early childhood student teachers utilizing 30 students who were studying in the first semester, the academic year 2016 in UdonThaniRajabhat University, Thailand which selected by cluster random sampling. The research instruments were the lesson plan of science experimental activities for early childhood on life cycle and the science process skills test. The research was carried out by the one group pretest-posttest design. The data were analyzed using mean, standard deviation, percentage and t-test for dependent. The results of this study was that early childhood student teachers who were given the science experimental activities for early childhood on life cycle have science process skills pretest mean score 8.10 (33.75%) after learning their posttest mean score is 21.70 (90.42%). The results show that each of the posttest mean score was higher than 75% and it was also higher than the pretest.
