第一步进入物理在酒厂
First Steps into Physics in the Winery
摘要:
在专业学校(即农业、电子或化学专家学校)的课程中,物理学被作为一项基本内容。学生在训练的最初几年接触物理学,然后继续学习职业科目,其中许多物理学的主题可能是有用的。然而,物理学与专业事务之间的联系很少是非常明确的。学生们常常觉得物理枯燥乏味,毫无用处,也就是说,离他们的兴趣很远。在这些学校,几乎总是需要物理实验室,但它并不总是存在。当地农业技术学院的物理老师要求我们为他们的学生实现实验室学习路径,因为在他们的学校物理实验室缺失。该学院是基安蒂地区唯一一所专门从事葡萄栽培和葡萄酒酿造的公立学校,并参加一年后的文凭,可以获得葡萄酒酿造师的资格。我们报告了一个学习路径实现从热平衡开始,以充分理解的措施与Malligand的沸点计,用于确定酒精饮料和水/酒精溶液的酒精浓度(酒精浓度按体积)一般。其目的是使有趣的措施,物理量,量热和状态转换连接到一个仪器,学生在他们的职业生涯中使用的功能。学生们的反馈和老师们的兴趣使我们相信我们在这方面走得更远。我们打算在不久的将来,让物理和职业学科的教师参与设计一个为期两年的物理课程,其中主要的物理主题将被引入,以解释通常在酿酒厂使用的工具和设备的功能。
英文摘要:
Physics is introduced as a basic matter in the curricula of professional schools (i.e. schools for agriculture, electronic or chemistry experts). Students meet physics in the early years of their training and then continue in vocational subjects where many physics' topics can be useful. Rarely, however, the connection between physics and professional matters is quite explicit. Students often feel physics as boring and useless, i.e. very far from their interests. In these schools it is almost always required the physics lab, but it does not always exist. The physics teachers of a local Agricultural Technical Institute asked us to realize a learning path in laboratory for their students, since in their school the physics lab was missing. This institute is the only public school in the Chianti area specializing in Viticulture and Enology, and attending a further year post diploma, allows the achievement of the qualification of Enologist. We report a learning path realized starting from thermal equilibrium to a full understanding of the measures made with the Malligand's ebulliometer, used for determining the alcoholic strength (alcohol concentration by volume) of an alcoholic beverage and water/alcohol solutions in general. The aim was to make interesting measures of physical quantities, calorimetry and state transitions connecting them to the functioning of an instrument that students use in their professional career. The feedback of students and the interests of their teachers convinced us to go further in this way. We intend in the next future to involve teachers of physics and vocational subjects in the design of a physics curriculum spread over two years in which the main physics topics will be introduced to explain the functioning of tools and equipment used, normally, in the winery.
