An engaging lesson presentation (37 slides) which gets students to test their practical skills by carrying out the four identification tests for oxygen, hydrogen, carbon dioxide and chlorine. The lesson begins by using a competition called “Guess the gas” where students have to used clues to identify the four colourless gases which will be used in the lesson. Moving forwards, students will meet the pieces of equipment that will be used in these tests. Practical instructions for each of the tests are included in the lesson so that students can produce the gas and then carry out the test. There are regular progress checks throughout the lesson so that students can assess their understanding. This lesson is suitable for both KS3 and GCSE students

A fully-resourced lesson which looks at the saturated hydrocarbons known as the alkanes and focuses on their structure and reactions. The lesson includes an engaging lesson presentation (38 slides) and an associated worksheet which is differentiated. The lesson begins with the introduction of the name of this group and then a step-by-step guide is used to show students how to draw the displayed formula. Once the first four have been drawn, students are shown how to calculate the general formula for the alkenes and then challenged to do the same for the alkanes. Moving forwards, students will meet the key term, saturated, and time is taken to ensure that the meaning of this word is understood in the context of this lesson. Once they have been introduced to bromine water, students are challenged to work out what will happen when this substance is added to an alkane and they have to explain their answer. The remainder of the lesson looks at the complete and incomplete combustion of the alkanes, focusing on the different products of these reactions and specifically the problems associated with carbon monoxide. There are regular progress checks throughout the lesson to allow the students to check on their understanding.

An informative lesson presentation (24 slides), accompanied by a set of differentiated question worksheets, which together guide students through calculating energy changes in reactions and then challenges them to apply their new-found knowledge. The lesson begins by asking the students to complete a sentence which details how energy is taken in to break bonds in the reactants and given out when bonds are formed in the products. The bond energy table is then introduced so that students understand how it will be used in questions. Moving forwards, a step by step guide is used to calculate the energy change value for two reactions and students are shown how to interpret the positive or negative result as endothermic or exothermic respectively. The remainder of the lesson asks the students to apply what they have learnt to calculate the energy change for two more reactions. This question worksheet is differentiated two ways so that students who need extra assistance can still access the work. This lesson has been designed for GCSE students
