bridge building

In Y6 we continued with our theme of 'Bridges' in Design Technology and looked at arched structures. After realising that an arch is much stronger than a beam ( using strips of paper across a gap and wooden blocks for weights) we set about making trapezoidal prisms (using a pre-printed net). 
We then tried to see if we could assemble them into arch - it worked - so long as the bottom blocks on each side were glued to the base sheet. Each block held the others in place, just like in a real arch!

We've displayed them alongside our appliqued riverscapes.
