· I
know what kinds of things change and cannot be changed back again after heating.
· I
have mixed ingredients to make a cake or biscuit and can explain how they had changed
after I heated them.
· I
can use science words and terms to describe these changes.
· I
have found out about the kinds of materials that will burn.
· I
know what they change into and that they cannot be changed back.
· I
can explain the differences between burning and heating using my science knowledge.
