Third and fourth class have been examining bridges. We looked at a range of bridges and discussed what materials were used and the designs used to make them strong. We researched how long it took to make different bridges and the amount of weight they can hold. We discovered that the longest bridge in the world in the newly opened bridge that connects Hong Kong to Macau and the mainland Chinese city of Zhuhai. It is 55km long. We had to concentrate really hard to draw intricate suspension bridges but we feel we did a good job. For science the children were given two pieces of paper and had to investigate how to make the paper into a strong bridge. We discovered that folding the paper and making an arch under the bridge helped make our bridges stronger. We'll never look at a bridge the same way again!
