3 structured lessons covering topics from AS Chemistry Alkanes from the OCR Specification Lesson 1: Properties of Alkanes To know alkanes are saturated alkanes containing sigma (σ)bonds that are free to rotate Explain the shape and bond angle round each carbon atom in alkanes in terms of electron pair repulsion Describe and explain the variations in boiling points of alkanes with different carbon chain lengths and branching in terms of London forces Lesson 2: Combustion of Alkanes To understand why alkanes are good fuels To recall the equations (both word and symbol) for complete combustion of alkanes To recall the equations (both word and symbol) for incomplete complete combustion of alkanes Lesson 3: Free Radical Substitution of Alkanes 1)To know what a free radical is 2) To describe the reaction mechanism for the free-radical substitution of alkanes including initiation, propagation and termination 3) To analyse the limitations of radical substitution in synthesis by formation of a mixture of organic products Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons, including using your own lesson PowerPoints, is a fundamental skill of a qualified/unqualified teacher that will be assessed during the scenarios outlined above

5 Well Structured GCSE Higher Tier Combined Science Lessons from the AQA Quantitative Chemistry Chapter Lesson 1: Relative Formula Mass To identify the relative atomic mass of an element from the periodic table To be able to define the term relative atomic mass To calculate relative formula masses from atomic masses Lesson 2: Mass Changes in Reactions To relate mass, volume and concentration To calculate the mass of solute in solution To relate concentration in mol/dm3 to mass and volume Lesson 3: Moles Describe the measurement of amounts of substance in moles Calculate the number of moles in a given mass Calculate the mass of a given number of moles Lesson 4: Moles and Equations calculate the masses of substances in a balanced symbol equation calculate the masses of reactants and products from balanced symbol equations calculate the mass of a given reactant or product. Lesson 5: Concentration of Solutions To relate mass, volume and concentration To calculate the mass of solute in solution To relate concentration in mol/dm3 to mass and volume Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation.

2 Lesson bundle covering the OCR Periodic Table Chapter on group 2 elements and compounds Lesson 1: Group 2 Elements By the end of this lesson. Students should be able: To know group 2 elements lose their outer shell s2 electrons to form +2 ions To state and explain the trend in first and second ionisation energies of group 2 elements and how this links to their relative reactivities with oxygen, water and dilute acids To construct half equations of redox reactions of group 2 elements with oxygen, water and dilute acids and to identify what species have been oxidised and reduced using oxidation numbers Lesson 2: Group 2 Compounds. By the end of this lesson students should be able: To know the reaction between group 2 metal oxides and water To state the trend in solubility and alkalinity of group 2 metal hydroxides To describe the uses of some group 2 compounds including their equations The teacher will be able to check students have met these learning objectives through mini AfL tasks for students to complete Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation.
