We talked about the story of the Three Little Pigs and we decided that the wolf in the story was really good at testing the building materials to see which was the strongest. We chose our own materials to test. We talked about the properties of our materials and shared them with the rest of the class. We used the fan to blow our finished wall designs and then discussed the most suitable material. Wood and plastic were the most successful.The others were too soft, too malleable or not the right shape.
