School Disco
Yesterday we had a school disco. It was organised by a committee of some of the kids who went on the Leadership Conference last month.
They raised money for sports equipment, and everyone had lots of fun. Here are some photos....

Science experiment. by Piper
Magic water
Firstly Mrs McLean got two clean stramboli jars the same size.
She filled one up with cold water, and the other jar with hot water.
Secondly she put two drops of orange dye in the hot water so the two will look different.
Next she put a piece of cardboard on top of the cold water.
Then she tipped the jar over and put it on top of the other jar
so the hot water is on the bottom and the cold on the top.
Penultimately the hot water started to swap places with the cold water
so they were now the same colour as the hot.
Finally the hot water and the cold had mixed.
This experiment shows us that the hot water molecules mix much better than cold water molecules.
also the hot water rises because hot water is lighter than cold water.

Hot and Cold water
We added dye to them both and this is what we noticed:
In the cold water the dye stayed together and gradually dropped to the bottom, as you can see on the right.
In the hot water the dye mixed through quickly and evenly without being stirred.
This was because the particles in the hot water were moving around by themselves, but the cold water didn't move around.
Science-A lot of air. Michelle Arama
Room 13 is learning about science and here is one of the experiments that we did:
Get a balloon and an empty narrow-necked soda bottle and a container or pot, and put boiling water in it right out of the jug.
Stretch the balloon over the neck of the bottle so there is no holes or gaps between the bottle and balloon, then place the bottle in the pot or container of hot water.
Then suddenly you will see that the balloon begins to inflate. This is because the hot air expanded and took over the cold air because hot air takes up more space than cold air. The hot air rises because hot is less dense than cold, and cold is heavier than hot.
And this experiment is seen in the world because of hot air baloons. They have fire to heat it and make it go up.
