Learning Outcomes:

1. Identify a change which leads to formation of new product(s) as a chemical change

2. Use word equations to represent chemical reactions (Note: chemical equations not required)

3. Recognise that chemical reactions involve a rearrangement of atoms, which are not created or destroyed

4. Recognise that mass is conserved during a chemical reaction

5. Show an awareness that there are different types of chemical changes such as combustion, thermal decomposition, oxidation (e.g. rusting and
   cellular respiration) and neutralisation.

6. Investigate the following chemical reactions between:

   • acids and alkalis;

   • *acids and metals; and

   • *acids and carbonates

7. Investigate the effect of acidic, alkaline and neutral solutions on indicators (include litmus paper, Universal Indicator and natural indicators
   obtained from plants)

8. Investigate the chemical changes that matter (i.e. element, compound or mixture) undergoes upon:

   • mixing (e.g., neutralisation)

   • heating (e.g., thermal decomposition)

   • exposure to light (e.g., photosynthesis)

   • interacting with oxygen (e.g., rusting and cellular respiration)

   • *using an electric current (e.g., electroplating) (Note: electroplating is stated as an example which may be used for students to observe visual changes; anode, cathode and reactivity series of metals not required)

9. show an awareness of how chemical reactions can benefit our lives (e.g., cooking, respiration) and cause harm to our health and environment
   (e.g., rusting, decay and burning).
