As part of our Island theme we looked at bridges as a means of getting to an island. Students began by looking at photographs of various famous bridges such as the Clifton Suspension Bridge, Sydney Harbour Bridge and Juscelino Kubitschek Bridge.  They then split into two teams and designed their own bridges.  The girls went for a truss style bridge with additional support underneath.  The boys designed a combination of an arch and a truss bridge.  We then used masses to test out the bridges strength with surprising results.  The girls’ bridge held 875 grams and the boys’ bridge held 400 grams.  Well done to the girls’ team!
