Mr. Hoffman’s Physical Science Lab Skill Soaring Straws


Students are to examine how gravitational potential energy of a straw depends on the elastic potential energy of the rubber band launcher.  Students have to construct the rocket launcher following laboratory procedures, use a balance to find mass of the rocket & measure the distance to which the rocket flies. Following the collection of data students must calculate the gravitational potential energy for each launch & answer critical questions.
