This week we have continued our experiments and have begun to think about making a test 'fair', and how we could only change one thing each time we did an experiment. I was impressed by the children who used all of their scientific knowledge to make logical predictions about what would happen.
Our experiment was to see out of three different sized cones, which would travel the highest when launched by our bottle.
Here were some of the predictions:
Smallest cone - this might go the highest as it was the lightest.
Medium cone - this might go the highest as it was a medium size, not too small and not too heavy.
Big cone - this might go the highest as it had more space to catch the air coming out of the bottle.
We discovered that in fact the smallest cone travelled the highest and it didn't matter who was hitting the bottle, the results remained the same.
