Year 3 planned and carried out an experiment to test which material was the most effective at muffling sound. The children discussed fair testing and how to make a scientific prediction. Ryan & Divine were our two students who were able to predict that the plastic carrier bags would be the best at muffling the sound from the shaker- even the adults were sure the fabric would be the best muffler! The children understood that it is exciting to get a prediction wrong and even professional scientists predict incorrectly every day!
