A house with three granaries

In Casa de Chouzas, three 19th-century granaries join the solarengo building highlighted by the Municipality. The set approximates two functions: inhabit and guard the harvest. Instead of looking only at the main house, it is also worth recognizing the importance of agricultural support constructions. The presentation of Vilar de Cunhas places this heritage in a plateau and mountain landscape, marked by agriculture and pastoral care. The house and the granaries can be read in this work context, without the source detailing the production of each property. The dating of the house is less firm: the municipality presents it as perhaps 19th century, while assigning the granaries to the 19th century. This difference must remain visible. The photo accompanying the reading shows the portal; it does not show the three granaries. The asset reference does not confirm access to the set.

Vamos experimentar?

  1. Look at the photo of the portal and list only the elements you can see.
  2. Compared to the three granaries mentioned in the text: what depends on the written description?
  3. Imagine a caption that distinguishes the frame of the photograph from the remaining patrimonial set.

A proposal to make at your pace, without collecting copies.

PROPOSTA 2 DE 2 · Between rivers and mountains

Compare three grain sizes

Geological complex of Cabeceiras de Basto · regional study

Granite also changes grain

In the study by A. Almeida, the granite complex of Cabeceiras de Basto does not have a single grain size. The classification uses three average intervals: 0,5–1 millimeter for fine grain, 2–4 millimeters for medium and 5–7 millimeters for coarse grain. In the last group, the author also mentions rare larger crystals, with 8–10 millimeters. This allows distinguishing two observations: the usual size of the grains and the presence of some crystals that stand out. The description does not transform each visible point of a photograph into a measurement. To compare sizes on an image, a scale is required; a screen magnification can make small grains look large. The study refers to three genetically independent series, although they have similar chemical composition ranges. Appearance is an entrance to the investigation, not all explanation of origin. On a wall or a facade, the grains arouse curiosity, but do not prove for themselves where the stone came from.

Vamos experimentar?

  1. In a millimetric ruler, 1 mm, 3 mm and 6 mm are examples within the three ranges described.
  2. Draws three small fields with points of different sizes, identifying them as a scaleless scheme.
  3. Adds some larger crystals to the third field. It distinguishes the average dimension of the presence of exceptions.

Exercise on paper. It does not require collecting rocks, scratching walls or removing fragments.
