As part of their work on STEM this term,  all of the P7 classes has been investigating what makes a strong structure.  for the last couple of week they have been working in teams of four to build their own geodesic dome using plasticene and cocktail sticks.

How does it work? – Geodesic domes are extremely rigid. Multiple interlocking triangles form incredibly strong structures. To deform or buckle a triangle you have to compress or stretch the lengths of the sides, which is hard to do as they support each other.
