More Science!!

Room 8 have been really enjoying undertaking a range of science experiments.  One of the recent ones that we did was to investigate the effect of weight and force and speed.  We a plastic milk bottle and then filled it with 200,400, 600 and 800 mls of water.  We made predictions about what would happen to the speed of the bottle as we put it down a zip line.  We found out that the bottles would move more quickly down the zip line as the weight became heavier!
