This study aims to analyze creativities and characters of students through project-based learning in designing experiments. Through the quasi-experimental method this research was conducted on 20 students who took experimental design courses. Through worksheets, product assessment sheets and attitude observation sheets the creativities and characters of students can be analyzed. The results showed that students creativities in making experimental designs in the form of flowcharts, to present, to create storyboards, to develop products from designing experiments had an average of 77.3, with good category. Meanwhile the characters developed were discipline with observable behavior that always came to the class punctually, spoke honestly, and remained confident even though the task that was doing was not satisfactory, the characters of responsibility with observable behavior was able to do the task without the help of others and diligently working on the task until it was finished.
