Primary 5 Science Investigation

This slideshow requires JavaScript.

Primary 5 have been investigating water hardness and softness.  We found that we have soft water in our taps, the water has between 0mg/L CaCO3 and 50mg/L of CaCO3.

We also investigated the Mpemba Effect.   Our results have shown that in most cases the cold water froze faster than the warm water.

However one result showed that the warm water froze faster, this is because of a variation in liquid amounts.

We concluded that in science experiments you can get lots of different results, our predictions are not always correct.  Mpemba noticed in 1963 that warm water froze faster than cold water, however many scientists argue with this conclusion.  The question whether warm water  or cold water freezes first is still being debated today.

Primary 6 finished their last session at St Maurice’s High School today as part of the Transition Programme.  Over the past three weeks, they have been working hard with Mr McConnell from the Technical Department to make a ‘Maths Game’, filing down their plastic and marking out it correctly.
