This last week in DT, 3S have been investigating different bridges. They have investigated different types of bridges, including a truss bridge, an arched bridge and suspension bridge. We discussed the differences and the functions of each bridge. They determined which one was the strongest. 

In readiness for creating our own bridges, 3S started by making their own miniature prototypes using art straws and sellotape. We worked well as a team to produce some fantastic work. Next week, we will get our models back out and evaluate how we did. When we have decided on how to improve, we will develop our ideas and alter our final design.
