We planned how we could use strong shapes to make a very strong bridge using popsicle sticks media type="custom" key="9787834"

We had a few problems constructing our bridges but we learnt from our mistakes and found ways around them media type="custom" key="9817529"

From making to breaking! We tested the strength of our bridges using fair testing. The winning bridge carried a load of 3 bricks and 16 dictionaries without breaking.

For our performance task groups had to design and make a model of a bridge suitable for spanning Clarks Beach to Te Toro .

It had to span 50cm and carry 1 Kg. Each group had to present its submission to the "Auckland Council " and explain its design.
