Page 1: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change
Page 2: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

Learning objectives

• that heating some materials can cause them to change

• that cooling some materials can cause them to change

Page 3: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

Heating something is causing its

temperature to rise. It is not setting it

alight.

Remember……

Page 4: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

Look at each picture.

Predict what will happen to the material when it is

heated.

Page 5: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

Decide whether these changes

are reversible or irreversible.

Page 6: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change
Page 7: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

This is a reversible

change

Page 8: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change
Page 9: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

This is an irreversible change

Page 10: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change
Page 11: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

This is an irreversible

change

Page 12: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change
Page 13: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

This is an irreversible change

Page 14: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change
Page 15: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

This is a reversible change

Page 16: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change
Page 17: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

This is an irreversible change

Page 18: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change
Page 19: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

This is a reversible change

Page 20: Learning objectives that heating some materials can cause them to change that cooling some materials can cause them to change

Now suggest materials that are

changed by cooling and decide whether these changes are

reversible or irreversible.
