In room 15 we have been learning all about science and we have been researching about physical changes and chemical changes. Physical changes are when a change occurs that can be reversed back to it's original state for example; you can melt an ice cube and it will go back to being an ice cube. A chemical change is when a change has occurred that can not go back to it's original state, often a new substance will form. For example; when you have spoilt milk and you can't repair it.
