In MST week in Design and Technology, Year 5 have been exploring and making bridges!  We looked at the common shapes in bridges and we noticed triangles were used in most bridges.  We found out that triangles are very strong shapes and create tension and compression which make a bridge really strong so it can withstand heavy loads.  We made spaghetti truss bridges in small groups and evaluated their success.  Finally, we made a wooden truss bridge using what we had learned!  We are really proud of our results and had lots of fun!
