We read a story called: “The Runaway Train” investigated our own runaway train. This time in the science investigation we were focusing on making predictions; we made predictions about which material on the ramp would slow down the train the best. Lots of us used the existing knowledge we had to help make our predictions. At the end of the day we carried out the investigation, some children from the class took on roles such as: investigator, health and safety officer, recorder, measurer and fair test checker.
