Today in 4ESO we have experienced how to calculate pi weighting.
The idea is to calculate the ratio between the volume(weight) of a cylinder and a prism which share the height and knowing that the base of the cylinder is inscribed in the square base of the prism.
Students of 1st course prepared the material, you can see photos below.
But we found a problem, the cardboard is not rigid enough, thanks to our French partner we have plastic models made in a 3D printer, using those models we have very accurate results for pi such as 3.13, 3,08 and 3,15.
It has been a lovely experience of collaboration between two different levels , subjects (technology and mathematics) and teachers. We will repeat soon!!!
