Uma abordagem experimental envolvendo massa, volume e densidade

Abstract

This paper presents a proposal for an experimental activity addressing concepts of mass, volume and density, based on everyday problem solving and having several manipulable materials as support. This proposal was applied with a 3rd year class of High School in a rural school at São Lourenço do Sul - RS, consisting of 19 students. This paper attempted to address in a practical way the concepts of mass, volume and density in order to lead the students to see the relation between these concepts and their differences. The problem-solving strategy and the use of different resources for the activities allowed greater interaction among students, so that they could exchange ideas, reflect and conjecture results as the questions were being exposed. We believe proposals of this nature when well planned are likely to contribute to the teaching and learning of various mathematical contents.
