• Give some examples of chemical reactions

• Explain the difference between a physical and chemical change

Chemical reactions – What to look for

Chemical reactions – What to look for

• There may be a change of colour

Chemical reactions – What to look for

• There may be a gas given off (bubbles)

Chemical reactions – What to look for

• There may be an energy change (gets hotter or colder)

• New substances are formed, and the change is usually difficult to reverse

Physical changes

Melting

Boiling

Condensing

Solidifying/freezing

Today’s lesson
