This study measured the effect of completing a BalloonSat project on student attitude toward science. Seven categories of student attitudes toward science were measured using the Test of Science Relate Attitudes survey (TOSRA). The research anticipated that the BalloonSat project would have similar effects on student attitudes as found in robotics projects, like FIRST. The researcher also investigated whether gender moderated the effects of the BalloonSat project. This study enrolled 138 students from three states and one Canadian province. Students were free to select membership in either the treatment group or the control group. Student attitude toward science was measured prior to the start of the study and at its completion. Mean scores for the control and treatment group were then compared using an analysis of covariance. The effect of the BalloonSat project only affected one attitude toward science, Leisure Interest in Science. The study did not find gender was a factor in the effects of the BalloonSat project. This study is the first study of the BalloonSat project on grade 7-10 students and provides some evidence that a BalloonSat project can impact middle and high school attitude toward science.
