Supported by positive student responses. The results of the knowledge test obtained the n-gain score by 0.98 in the high category. The percentage value of the science process skills test which includes the components of formulating problems, formulating hypotheses, identifying variables, collecting data, analyzing data and making conclusions respectively are 100%, 96%, 98%, 100%, 94%, and 96% with very high categories.
