In this activity students investigate the effect that thrust has on rocket flight Students will make two paper rockets that they can launch themselves by blowing through a straw These “strawkets” will differ in diameter such that students will understand that a rocket with a smaller exit nozzle will provide a larger thrust Students have the opportunity to compare the distances traveled by their two strawkets after predicting where they will land Since each student will have a slightly different rocket and launching technique they will observe which factors contribute to a strawket’s thrust and performance
