physical change




WALT  see if sugar can change from a solid to a liquid and if that can be reversed.
  1. Mr Naidoo mixed sugar with water then it dissolved into a liquid .
  2. Then we put the liquid into the frying pan , then after a minute or two we went back to the pan and then we turned the pan off and we let it cool down .
  3. Then when it cooled down we went to look if the sugar went back to solid and it did .
  4. When we looked at it some of us were surprised that it even went back to solid .
I already knew that sugar/water  can be reversed .
So I hope you have learned something  .
