    You will be able to:
    • distinguish chemical from physical change.
    • recognise evidence for a chemical change or 
      reaction.
    • understand that chemical reactions release 
      energy to the surroundings while other 
      absorb energy.
    • know that oxygen is needed in oxidation 
      reactions such as burning.
    • be aware of usefulness of chemical reactions 
      in everyday life.
                                                               1.1
                                             2
  Is a chemical reaction taking 
  place here?
                                                   1.2
                                    3
 Look at the pictures and discuss these applications 
 of chemiluminescence.
                                    4
  Do you think any heat energy 
  is release in glowstick 
  reactions?
                                                                 Simulated images
                                      5
                                      BEFORE
  • You will do an investigation to 
   study the energy released in 
   the glowstick reaction.                                          Glass Vial
                                      Hydrogen Peroxide Solution
  • See how the glowstick reaction 
   is affected by temperature.        Phenyl Oxalate Ester and 
                                      Fluorescent Dye Solution
  • Learn about the everyday uses 
   of glowsticks.
                                                                     Plaster Casing
  • What are the two reactants?
  • What is the purpose of the 
   hydrogen peroxide solution in 
   the drawing?
                                      AFTER
                                            6
