Is it reversible or irreversible?

Today in Science we have been learning about changes of state. We used chocolate, egg, cheese, b utter, plasticine, wax.  We have been testing out wether they would melt or not.  And turn into liquid.  Then you leave it for a while in the cup it will turn back into the same solid.  This is called a reversible chnage.  Juliette.

Well I thought the science lesson was quite fun and some of it was quite hard cos we had to keep the cus in the water properly so it would melt. In our groups we did experements to find out if they would melt nd then whether it was reversible or irreversible (it means doesn't turnback into what it started).
