  1. Heating and Cooling Materials

  2. Learning objectives • that heating some materials can cause them to change • that cooling some materials can cause them to change

  3. Remember…… Heating something is causing its temperature to rise. It is not setting it alight.

  4. Look at each picture. Predict what will happen to the material when it is heated.

  5. Decide whether these changes are reversible or irreversible.

  6. This is a reversible change

  7. This is an irreversible change

  8. This is an irreversible change

  9. This is an irreversible change

  10. This is a reversible change

  11. This is an irreversible change

  12. This is a reversible change

  13. Now suggest materials that are changed by cooling and decide whether these changes are reversible or irreversible.
