A well structured lesson including starter activity, main work tasks with answers included on empirical and molecular formulae By the end of the lesson students should be able to: Understand what is meant by ‘empirical formula’ and ‘molecular formula’ Calculate empirical formula from data giving composition by mass or percentage by mass Calculate molecular formula from the empirical formula and relative molecular mass. Note: the starter activity involves students self assessing their homework on moles and the ideal gas equation (Homework questions and answers are included in this resource) 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

A complete lesson including starter and main work task on the ideal gas equation Lesson begins with exam style questions to recap on what students should know about moles By the end of the lesson, students should be able to: Recall the ideal gas equation Understand the properties of an ideal gas Rearrange the ideal gas equation to determine either pressure, temperature, moles or volume Teacher will be able assess students understanding and progress throughout the lesson via mini AfL tasks Students complete a 20-30 minute main work task at the end of the lesson on the ideal gas equation Worked example answers to the main work task are provided to allow students to self assess their answers Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation.

A complete lesson including starter activity, main work task, bonus task and answers on Avogadro’s constant and calculating moles using the mole equation The lesson begins with a 5-10 minute starter task (DO NOW) on previous KS5 knowledge about relative atomic mass of elements and calculating the relative molecular mass of compounds By the end of this lesson KS5 students should be able to: Know that the Avogadro constant is the number of particles in a mole Calculate the number of moles present in a given mass of an element or compound using the mole equation Rearrange the mole equation to calculate either the number of moles, Mr or mass of an element or compound The teacher will be able to check students have met these learning objectives through mini AfL tasks for students to complete as well as a 20-30 minute independent work task All tasks have worked out answers which will allow students to self assess their work in the lesson Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation.
