Construir una balanza para condiciones de ingravidez

this work presents the educational treatment of a problem such as 'weighing' bodies where there is no gravity. it looks at the teaching strategies used with the students. these strategies give them the chance to think, produce a hypothesis and analyse results on topics related to the concepts of mass and weight, plus the kinematics and dynamics of simple harmonic movement. the work shows how students get involved in the task and, with the teacher's help, manage to provide a theoretical and experimental solution to the problem, and create scales to measure where there is no gravity.
