As part of our Crest experiments we completed the 'Confusing Cans'. We had a number of tin cans which had their labels removed. We looked at them and discussed the weight of each one, listened to the sound it made when it was shaken and then predicted what might be inside each can. We then opened the cans to see who was correct.
We also rolled the cans down a ramp and made predictions about which would roll the furthest distance. We then measured to see which traveled the furthest and discussed whose prediction was the closest.
