For our model,the materials used were cardboard,straws,strings,ice-cream sticks,cotton,glue and scotchtape.we mainly used cardboard for our model because in our opinion,cardboard is very strong,solid and reliable.It is also very easy to work with.We used cardboard for the base,"treehouses",the art room and the swing.Next,we used straws to build the swing stand.We used reused straws to build the swing stand because it already had the straight shape and it is also easy to work with.We used strings to represent the ropes for the swing and the rope swing because it is flexable.The ice-cream sticks were used for the fence because not only are the ice-cream sticks colourful,they are also stable and solid.They too,have a good fence shape.The cotton were used as the floor because it resembles padded floor.(147 words)
