For engineers week we looked at what makes bridges so strong. In teams we made bridges from paper and balanced a tray on top and tested how many marbles each bridge could hold.We were also looking into the food pyramid. The boys loved this sorting activity. They had excellent conversations and worked as a team to place the food on the right area.We also learned about working dogs in our community and were lucky to have the Defence Force dog Fionn come to visit our school with his trainer James.
