Quantitative chemistry experiments, with low-cost materials, for high school students

Abstract

Quantitative chemistry experiments, with low-cost materials, for Non-Compulsory Secondary Education students. One of the reasons that explain why there is not enough practice for non-compulsory secondary education students is the low provision of laboratory material public high schools. To try to relieve this problem, there have been and there are many attempts to use homemade, recycled or acquired materials through the internet, trying to bring experimental work to students. However, most of these proposals focus on the qualitative aspects of physical-chemical phenomena. In this article we make a proposal, which goes further, with concrete examples of quantitative experiments, using low-cost materials, in which students must take measurements, interpret data and use simple software programs to analyze the results obtained and present their findings or conclusions.
