| Subject | Chemistry | Week | 16 |
| Duration | 60 minutes | Form | SHS 2 |
| Strand | CHEMISTRY OF CARBON COMPOUNDS | Sub-Strand | FUNCTIONAL GROUP CHEMISTRY |
| Learning Outcome(s) | 2.3.2.LO.1 - Explain the source, structure, nomenclature, properties, uses of the various classes of organic compounds and the test for their functional groups | ||
| Content Standard | 2.3.2.CS.1 | ||
| Learning Indicator(s) | 2.3.2.LI.5 - Explain the structure, nomenclature, preparation, properties and uses of alkanoic acids as well as their characteristic test. Collaborative Learning Approach: • Generate members of alkanoic acids (carboxylic acids) up to C6. • Apply IUPAC rules to name alkanoic acids up to C6 and their isomers. • Write chemical equations for the production of alkanoic acids (i.e., from primary alkanols, alkanals, alkyl benzene). • Discuss the biological way of producing ethanoic acid from acid fermentation. • Discuss the physical properties of alkanoic acids (solubility in water, boiling point, melting point, density, volatility). • Account for the acidity of alkanoic acids and state the factors that affect their acidity. Exploratory Learning: Plan and carry out simple test tube experiments or watch videos or use virtual laboratory to investigate the reactions of alkanoic acids with the following substances: Na, NaOH, NaHCO3, Na2CO3, NH3, ROH, LiAlH4 | ||
| Lesson Focus | Explain the structure, nomenclature, preparation, properties and uses of alkanoic acids as well as their characteristic test. | ||
| Previous Knowledge | Learners recall related ideas, vocabulary or experiences from earlier lessons and everyday contexts. | ||
| Lesson Objective(s) | Describe the key idea in: Explain the structure, nomenclature, preparation, properties and uses of alkanoic acids as well as their characteristic test. Apply the idea through guided and independent learning activities. Demonstrate understanding through oral responses, written work or practical performance. | ||
| Essential Question(s) | What chemical model, relationship, evidence or calculation is central to Explain the structure, nomenclature, preparation, properties and uses of alkanoic acids as well as their characteristic test. Collaborative Learning Approach: • Generate members of alkanoic acids (carboxylic acids) up to C6. • Apply IUPAC rules to name alkanoic acids up to C6 and their isomers. • Write chemical equations for the production of alkanoic acids (i.e., from primary alkanols, alkanals, alkyl benzene). • Discuss the biological way of producing ethanoic acid from acid fermentation. • Discuss the physical properties of alkanoic acids (solubility in water, boiling point, melting point, density, volatility). • Account for the acidity of alkanoic acids and state the factors that affect their acidity. Exploratory Learning: Plan and carry out simple test tube experiments or watch videos or use virtual laboratory to investigate the reactions of alkanoic acids with the following substances: Na, NaOH, NaHCO3, Na2CO3, NH3, ROH, LiAlH4? How can laboratory observations, particle models, equations, graphs or quantitative data be used to explain the chemistry? How can the chemical principle from this lesson be applied to predict the behaviour of a new substance or reaction? | ||

| Teaching & Learning Resources | Chemistry textbook/reference materials Whiteboard/markers Learners' notebooks Periodic table MATERIALS Molecular models Video of greenhouse effect, toxicity of CO, acid rain Worksheets with task on naming, isomer, and properties Worksheets with tasks on naming, isomers, properties, uses of alkenes Video of preparation of ethyne Worksheets with tasks on naming, isomers, properties, uses of alkynes Materials to design alcohol breath analyser Kit for esterification reactions Na, NaHCO3, PCl5, C2H5OH, LiAlH4 Worksheets on reactions of benzene WEBSITE Virtual lab/video on laboratory and reactions of alkanoic acids Virtual lab/video on laboratory and industrial preparation of alcohol Virtual labs on preparation of alkene, test for alkenes Virtual lab on preparation of alkynes Videos on the topic: khanacademy.org CHARTS Charts on homologous series of alkanes, fractionating column Charts on uses of alkynes Charts on uses of alkenes Chart on uses of benzene Chart on classes of alcohols, uses of alkanols | ||
| Key Notes on Differentiation | |||
| Content | Use particle diagrams, colour-coded equations, formula prompts, worked examples and simplified data tables for learners who need support. Extend advanced learners with multi-step calculations, unfamiliar data, mechanism/property comparisons or more demanding analytical interpretation. | ||
| Process | Use mixed-ability grouping with rotating roles such as apparatus manager, recorder, calculator, safety monitor and presenter during practical/problem-solving work. Where apparatus or chemicals are unavailable, use curriculum-aligned simulations, videos, virtual laboratories, data sets and teacher demonstrations without changing the learning objective. | ||
| Product | Allow evidence such as balanced equations, calculations, graphs, molecular/particle models, practical reports, chromatogram interpretations, comparison tables or oral explanations. Assess chemical accuracy, safe procedure, correct units/notation, quantitative reasoning, evidence interpretation and ability to justify conclusions. | ||
| Success Criteria | Learners use correct subject vocabulary. Learners complete the main task with reasonable accuracy. Learners explain or demonstrate how the concept applies in a new situation. | ||
| Homework | Answer structured questions and identify one everyday application of the concept. | ||
| Lesson Activities | |||
| Stage | Teacher Activity | Learner Activity | Assessment / DoK |
| Starter10 minutes | Present a diagram, specimen, data set or everyday situation connected to the structure, nomenclature, preparation, properties and uses of alkanoic acids as well as their characteristic test and ask learners what they observe. | Share prior knowledge, listen to peers and record the lesson question in their notebooks. | Not provided. |
| Activity 115 minutes | Use a labelled diagram, model, experiment, data table or safe demonstration to explain the structure, nomenclature, preparation, properties and uses of alkanoic acids as well as their characteristic test. | Observe carefully, record key terms and answer oral questions. | Ask learners to identify the key feature, variable, process or relationship. |
| Activity 220 minutes | Guide groups to observe, classify, measure, compare or explain evidence related to the structure, nomenclature, preparation, properties and uses of alkanoic acids as well as their characteristic test. | Work in groups to complete the observation, classification, measurement or explanation task. | Review group responses for accurate science vocabulary and evidence. |
| Activity 310 minutes | Give a new case, data set or observation and ask learners to predict or explain the outcome. | Apply the concept to the new case and support the answer with evidence. | Use an exit task that asks for a prediction, explanation or calculation. |
| Lesson Closure | Summarise the structure, nomenclature, preparation, properties and uses of alkanoic acids as well as their characteristic test and correct one common misconception using learner examples. State one thing learned and complete the exit response. | ||
