Science – Strong Structures

Today we learned about shapes which make structures strong.  This is important SCIENCE and we will be talking about what made it a “Fair Test” tomorrow.  Great teamwork today and we certainly proved that triangles are much stronger than squares – even when they are 3D cubes!

All those bits of pasta and marshmellows!

First we tested how strong the triangle and square shapes were.

Then we built the 3D cube and triangular pyramid.  We tested how strong they were and found that the pyramid stood strong but the cube twisted and collapsed!

 

Then we made them stronger but adding more pasta to create more triangles!
