Marble Run
In our science topic fair testing, we conducted an experiment called
marbel run.We chose a large marble amd a small marble.
Which marble do you think is faster?


To make sure we have conducted a fair test, we have to select our marbles cerfully but to make sure in every other way the marbles
were identical but we made sure that the only difference is the size each marble was made out of glass the same colour, and had the same pattern.The only variable was the size and the proportionol weight.


The result was that the big marblewent down the trackand the small marble got knocked off the track.
