|Title: Alkanes and Alkenes |Date: 29th Apr 2015 |

|Class: Y11 Chemistry |Time: 10:15 – 12:05 |

|Curriculum & scheme of work references: |

|SACE Chemistry Stage 1 |

|Carbon Chemistry Hydrocarbons |

|Organic Nomenclature |

|Types of formulae |

|Functional Groups |

|Homologous Series |

| |

|Darwin High School scheme of Work |

|Prior knowledge: Prior Learning about alkanes structure as well as definind saturated and unsaturated hydrocarbons |

|Learning objectives: Understand the reactivity differences of saturated and unsaturated hydrocarbons |

|Learning outcomes (catering for different abilities) |

|By the end of this lesson: |

|all pupils will be able to: Predict the reactions of given alkanes vs alkene counterparts |

| |

|most pupils will be able to: Give the hydrocarbon combustion reaction’s products |

| |

|more able pupils will be able to: Write balanced equations for the complete combustion of hydrocarbons and show the reaction with |

|Bromine water |

|Assessment of learning outcomes. I will check learning outcomes by: |

|Participation in group discussion, answers to questions from teacher, |

|Resources required: |

|Alkanes and alkenes practical equipment |

|Keywords / Notation / Convention etc. |

|Hydrocarbon, combustion, bromine, addition, combustion , homologous series |

| |

|Time |Pupil / teacher activity and key questions |

| |Teacher activity |Pupil activity |

|10:20 |Introduce alkenes – brief outline, show the difference between|Listen, ask questions |

| |alkanes and alkenes with respect to structure | |

|10:25 |Introduce the practical activity. Emphasis on safety. Then on |Listen, Make notes, answer questions in group discussion |

| |observing the reactions, how to make useful observations | |

|10:30 |Split group into half, allow some pairs to begin the |Practical experiment, answer discussion questions |

| |experiment, the other half need to write up method before | |

| |answering questions | |

|10:50 |Swap groups when appropriate. allow some pairs to begin the |Practical experiment, answer discussion questions |

| |experiment, the other half need to write up method before | |

| |answering questions | |

|11:20 |Bring class together to discuss the results |Listen, make notes, ask questions |

|11:30 |Make notes on combustion reactions |Answer questions on combustion, try to write balanced |

| | |equations for complete combustion of given organic molecules|

|11:40 |Make notes on alkenes, Alkyne. |Complete alkanes, alkenes, alkynes comparison table |

|11:55 |Brief introduction to Alcohols. With reference to “another | |

| |addition reaction of unsaturated hydrocarbons…. | |

|Lesson Evaluation |

|Which learning outcomes did the pupils achieve? |

|all pupils will be able to: Predict the reactions of given alkanes vs alkene counterparts achieved |

|most pupils will be able to: Give the hydrocarbon combustion reaction’s products needs further attention (good opportunities to revisit |

|this throughout each new homologous series) |

|more able pupils will be able to: Write balanced equations for the complete combustion of hydrocarbons and show the reaction with |

|Bromine water needs further attention |

|How do you know these objectives were achieved? |

|Students were able to reflect on the practical and complete discussion questions to test their knowledge of the addition reaction with |

|alkenes. |

|Some students could write balanced equations for combustion of hydrocarbons but most had difficulty in balancing the equations even |

|though they could recognise the products of the reaction. |

|Which learning objectives did the pupils not achieve? |

|Which learning outcomes did the pupils achieve? |

|all pupils will be able to: Predict the reactions of given alkanes vs alkene counterparts achieved |

|most pupils will be able to: Give the hydrocarbon combustion reaction’s products needs further attention (good opportunities to revisit |

|this throughout each new homologous series) |

|more able pupils will be able to: Write balanced equations for the complete combustion of hydrocarbons and show the reaction with |

|Bromine water needs further attention |

|What action will you take next lesson to ensure that unachieved objectives are addressed? |

|I will re-introduce the concepts of combustion reactions with each new homologous series to allow students to practice and master |

|(hopefully) the skill. |

|What aspects went well? |

|Students were able to access the practical work and got a lot out of it – they were then able to use their observations to discuss the |

|explanation of the reaction to differentiate saturated and unsaturated compounds. |

|Did you learn any useful management strategies? |

|Students need specific direction in practical work even though they are very independent with respect to other learning activities. The |

|practical would have been quicker with very specific instruction. Although I do feel that the students learned a lot through discovering|

|and asking about skills rather than having everything shown. |

|If you taught this lesson again, what would you change? |

|I would ensure that students waiting for fume cupboards had work to complete that was familiar rather than new, this did distract |

|slightly from the aims of the lesson and was a good opportunity to consolidate some old skills. |

|What will you change in your subsequent teaching as a result of what you have learnt from this lesson? |

|Carefully “script” practical instruction, allow time for consolidation of previously taught work, |
