Granny likes sugar in her tea. She gets very cross when she finds sugar in the bottom of the cup. "What a waste! This sugar hasn't dissolved!" she complains.

Help granny. Plan a test to find out the best way to dissolve sugar.

Should granny change her sugar, the temperature of the tea, or how much she stirs?

* How can you make sugar dissolve quickly?

* Why do you think this happens?


Imagine you have some tea cups, some different sorts of sugar - cube sugar, granulated sugar, caster sugar - and some spoons, as well as a pot of tea.
