This lesson revisits the topic of random and systematic errors and also challenges students on other scientific skills such as identifying variables. Students tend to find this topic confusing, so the PowerPoint and accompanying resources have been designed to support them to identify whether an error is random or systematic and then to understand what to do next. The lesson guides the students through a series of real life examples and shows them how to spot each type of error. There is a considerable mathematical element to this lesson, including the calculation of means or missing values in a table. The lesson concludes with a series of exam-style questions where the students have to apply their understanding of identifying errors, variables and calculating means.

This lesson has been written for GCSE students, with the main focus being to introduce reversible reactions, show them how to represent them in both word and symbol equations, and to look at some well-known examples. Related topics such as the position of the equilibrium and endothermic and exothermic reactions are briefly mentioned so that students can recognise the potential crossover between topics. Some time is taken during the lesson to challenge the students to write a balanced symbol equation having been given a description of a reversible reaction. This task is differentiated with an assistance sheet so that all are able to access the learning. There are a number of these progress checks in this short lesson so that students can assess their understanding on a regular basis. Students will learn that the reaction in one direction will be exothermic and why this matters in terms of temperature and the equilibrium position. Increasing pressure and the number of moles is also discussed and an answer explained.

A fully-resourced lesson which uses a step-by-step guide to show students how to write fully balanced symbol equations. The lesson includes an engaging lesson presentation (38 slides) and associated worksheets containing questions which iaredifferentiated. The lesson begins by talking the students through the three steps involved in writing a chemical symbol equation. The first step involves writing in the formula for the elements. Students are introduced to the term, diatomic, and shown the 8 molecules that have to be written as a pair of atoms. Moving forwards, students are shown how to write chemical formulae for ionic compounds. They are reminded of how to use the group of the Periodic Table to work out the ion charge and how this is crucial when writing the formula. They are also shown how to write formulae which include brackets which is necessary when the charged molecules are involved. Finally, students are reminded of the rules of balancing symbol equations. There are progress checks at each stage so that students can assess their understanding and any misconceptions can be be addressed immediately. Time is taken to talk about state symbols, in case the exam question requires these to be included in the equation. The final section of the lesson involves students bringing their new-found skills together to write symbol equations for a range of reactions, including a neutralisation and reversible reaction. This task is differentiated so that students who need a little bit of assistance can still access the work. This lesson has been written for GCSE students (14-16 year olds in the UK)

An engaging and informative lesson presentation (43 slides) that shows students how to write accurate chemical formulae for ionic compounds. In order to write accurate chemical formulae, students need to know the charges of the ions involved. For this reason, the lesson begins by reminding students how they can use the Periodic Table to work out the charge of the charged atoms. Students are shown how they can use these ion charges to write the formula and then are given the opportunity to apply this to a number of examples. Moving forwards, students are shown how some formulae need to contain brackets. The lesson finishes with a competition called “Ye Olde Chemical Formula Shop” where students get points if they are the first to work out the formula of a given substance. This lesson has been written for GCSE students.

This fully-resourced lesson describes how to calculate the concentration of solution in grams per decimetres cubed and mol per decimetre cubed. The lesson PowerPoint and accompanying questions which are differentiated have been designed to cover points 1.49 & 5.8 of the Edexcel GCSE Chemistry specification. The lesson begins by introducing students to volumes in decimetres cubed and time is taken to ensure that students are able to convert to this measurement from volumes in centimetres cubed. Moving forwards, students are shown how to calculate the concentration in both units through the use of worked examples and then they are challenged to apply this to a series of exam-style questions which have been differentiated so students of differing abilities can access the work

A detailed lesson which uses a step by step guide to take students through titration calculations. The lesson begins by looking at jey terminology such as the “rough” and “titre”, which are discussed and explained so that there isnt any confusion. Time is taken to go over key steps in the method, such as using the molar ratio from the equation, so that students are prepared for these if they encounter in an assessment. This lesson has been designed primarily for GCSE students (14 - 16 year olds in the UK) but is suitable for older students covering this at A-level

A concise lesson presentation (22 slides) that looks at how catalysts affect the rate of a chemical reaction and focuses on the Science behind this topic. The lesson begins with the introduction of the key term and its definition to ensure that students are confident in the use of a catalyst in the correct context. More key terms like “activation energy” are introduced and links made to related Chemistry topics such as endothermic and exothermic reactions. Students are challenged to show how the activation energy will differ in the presence of a catalyst. The rest of the lesson involves a practical and the collection of results so that students can compare their data against the theory which was introduced earlier in the lesson. This lesson has been designed for GCSE students.
