I have been delighted to discover Class 5 is full of scientists ! We have been conducting experiment after experiment this term, to determine the properties of different materials, and they have shown themselves to make excellent predictions and conclusions.  We have been testing the hardness, thermal and electrical conductivity (amongst other properties) of different materials. Here, the class are seeing whether their predictions about which materials thoroughly dissolve in water are correct. For this super group of scientists, it was not a problem.  Well done!
