This is a fully-resourced lesson that looks at the meaning of a limiting reactant in a chemical reaction and guides students through how to apply this to a number of calculations. Step by step guides are used to go through worked examples so students are able to visualise how to set out their work. The lesson begins with a fun analogy involving sausages and potatoes so that students can identify that the potatoes limited the sale of food. Alongside this, students will learn the key term excess. Some time is then taken to ensure that students can spot the limiting reactant and the one in excess in actual chemical reactions and method descriptions. Moving forwards, students will be guided through two calculations that involve limiting reactants - those to calculate the theoretical yield and the other to calculate a balanced symbol equation. Other skills involved in these calculations such as calculating the relative formula mass are recalled and a few examples given to ensure they are confident. The question worksheet has been differentiated two ways so that any students who need extra assistance can still access the learning. This lesson has been written for GCSE students.

This lesson has been designed to guide GCSE students (14 - 16 year olds in the UK) through the steps involved in gas calculations. As you can see in the cover image, this lesson uses a step by step guide format to go through each of the critical stages. Hints and tips are given along the way and worked examples are used so that students can visualise how to set out their working. Important terminology such as room temperature and pressure (RTP) and limiting reactant are explained so that these do not cause issues. Students are given the opportunity to test their skills against some gas calculation questions which have detailed mark schemes and explanations to enable them to fully self-assess.

A short lesson which includes a lesson presentation (27 slides) and a hint worksheet and looks at redox reactions that involve oxygen and electrons. When focussing on oxygen, the lesson uses the example of extracting metals by reacting them with carbon to show how the metal is reduced and the carbon is oxidised. Key terminology such as reducing agents are also discussed. The important topic of electrolysis is used when teaching about the redox reactions that involve electrons and students are reminded about half equations. This lesson has been designed for GCSE students (14 - 16 year olds in the UK) but is suitable for other ages

An engaging lesson presentation (33 slides) which walks students through the main steps in the extraction of iron from its ore. The lesson begins by challenging the students to recall the reactivity series of metals and specifically the position of iron in relation to carbon so they recognise that it can be extracted by reduction with carbon. Key skills from other Chemistry topics are tested during the lesson such as writing chemical formulae and redox reactions. The rest of the lesson involves a step-by-step guide where students are given a passage and a symbol equation with something missing which they have to complete. This task ensures that students recognise the products, formulae and state symbols at each stage. A number of quiz competitions are used during the lesson to maintain engagement and progress checks have been written into the lesson at regular intervals so that students can assess their understanding. This lesson has been written for GCSE students and fits in nicely with other resources that are uploaded (extracting metals and extracting aluminium).

This lesson describes an ion as an atom with a positive or negative charge, and explains how cations and anions are formed in ionic compounds. The lesson PowerPoint and accompanying worksheet have been designed to cover points 1.22 - 1.24 of the Edexcel GCSE Chemistry specification and also covers the same points on the Combined Science course. The first part of the lesson focuses on atoms and specifically on getting students to recall that they contain the same number of protons and electrons and this is why they have no overall charge. By ensuring that they are confident with this fact, they will be able to understand why ions have a charge. Students will learn that ions have full outer shells of electrons and this change in the number of this sub-atomic particle leads to the charge. They are shown examples with aluminium and oxide ions and then are challenged to apply this new-found knowledge to a task where they have to explain how group 1, 2, 5 and 7 atoms become ions. The final part of the lesson looks at how ion knowledge can be assessed in a question as they have to recognise the electron configuration of one and describe how many sub-atomic particles are found in different examples. There are regular progress checks throughout the lesson to allow the students to check on their understanding. This lesson has been written for GCSE students but could be used with higher ability KS3 students who are looking to extend their knowledge past basic atomic structure

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 fully-resourced lesson which looks at the chemical reaction that is aerobic respiration and ensures that students can apply their knowledge to application questions which challenge them to make links to related topics. The lesson includes a practical-based lesson presentation (19 slides) and associated worksheets containing differentiated questions. The aim of the beginning of the lesson involves getting students to understand the term, concentration, so that they are able to use it accurately in their descriptions. This is a term which is commonly wrongly used by students. Moving forwards, students will carry out a practical to collect valid results so that they can apply their knowledge of concentration to explain a trend. Certain practical skills are challenged during the lesson such as the drawing of a results table to display the results. A worksheet containing questions on the practical is differentiated so that students who need assistance are still able to access the learning. This lesson has been designed for GCSE students but can be used with KS3 students who are learning about chemical reactions.

There are regular progress checks, with explained answers, so that students can assess their understanding.

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 informative lesson presentation (24 slides) that looks at the relative size of the nanoparticles and explains why they are so effective for a range of purposes. The lesson begins by looking at exactly how small nanoparticles are and ensures that students can recognise this size in a range of ways, including standard form. Moving forwards, in order to help students to understand why these nanoparticles are being used in a lot of different ways, students are introduced to bulk materials. Included in the remainder of the lesson is calculating the surface area to volume ratio so this can be used as a comparison point. There are regular progress checks throughout the lesson so that students can assess their understanding. This lesson has been written for GCSE students.

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.
