Investigating how materials can change shape when heated.
Today in class we looked at materials that can change shape when you heat them up. We discussed which materials can melt into different shapes. We also discussed how some materials such as chocolate and ice can be heated to form a liquid and then when cooled they change back to a solid shape. Some children commented that materials such as eggs and cake mixture cannot be changed back into a liquid after they have been heated.
Then we all made a chocolate biscuit.
