We have been exploring changing state and reversible changes with CHOCOLATE ! We made predictions such as.....
'If the chocolate cools, it will become a solid'
'It will become a solid after 15 minutes'
'It will go lumpy'
'It will become a solid, then back to a liquid.'
Then we melted chocolate and coated the backs of spoons with it to see what happened when we left it to cool overnight. See our results below....
