At Pt England school the intermediate year 7s and year 8s do a rotation. Classes 5,4,3,2 and 1 are all switched to others. My class was in Science with Mr Barks and we practise putting two or three different masses of chemical liquid like Corn syrup,water,Veg oil and dish soap. The first thing that happened was that Mr Barks put a little bit of veg oil and dish soap in a separate cup. Mr Barks then told us about the different masses about these liquids and Dish soap had a higher mass.
So if we put the cup that has the Veg oil in it on the Dish soap the veg oil will stay on top because its lower mass. But if you switch it around the dish soap will stay below the oil cause of the mass. After that our teacher put in a little ice cube then we had to observe it, When that did happen the ice was taking a long time to melt.
After that he went to tell to pack up because it was nearly home time already. His class coming back from their class to get ready to go home. The cups that had the liquid were emptied in the bin and made sure there was nothing on the table. It was fun doing Science with Mr Barks but tomorrow It would be cool if we do something a bit dangerous.
