Water Rockets. Get Funny With Newton's Laws

Abstract

The study of the movement of the rocket has been used for decades to encourage students in the study of physics. This system has an undeniable interest to introduce concepts such as properties of gases, laws of Newton, exchange between different types of energy and its conservation or fluid mechanics. Our works has been to build and launch these rockets in different educational levels and in each of these ones have introduced the part of Physics more suited to the knowledge of our students. The aim of the learning experience is to launch the rocket as far as possible and learn to predict the travelled distance, using Newton's laws and fluid mechanics. After experimentation we demonstrated to be able to control the parameters that improve the performance of our rocket, such as the fill factor, the volume and mass of the empty bottle, liquid density, launch angle, pressure prior air release. In addition, it is a fun experience can be attached to all levels of education in primary and high school.
