An engaging lesson presentation (42 slides) and associated worksheet that uses a combination of exam questions, understanding checks, quick tasks and a quiz competition to help the students to assess their understanding of the topics found within the Chemistry unit C5 (Energy changes) of the AQA GCSE Combined Science specification (specification point C5.5). The lesson includes useful hints and tips to encourage success in assessments. For example, students are shown how to use the energy change in a chemical reaction to work out if it is an endothermic or exothermic reaction. The topics that are tested within the lesson include: Endothermic and exothermic reactions Reaction profiles Calculating energy changes in reactions Students will be engaged through the numerous activities including a summary round called “E NUMBERS” which requires them to use all of their knowledge to work out the type of reactions that are shown.

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.

A fully-resourced lesson which explores how the composition of different alloys is related to their properties and their uses. The lesson includes an engaging and informative lesson presentation (38 slides) and an associated differentiated worksheet. The lesson begins by challenging the students to use their Chemistry knowledge of numbers to come up with the letters of the word alloy. Students are introduced to the definition of this key term and then use a wordsearch to find both the names of the alloys but also the metals that are found in these mixtures. The main aim of this lesson is to get students to understand why alloys are chosen for jobs rather than pure metals and there is a focus on atoms and their arrangement. Students are challenged to use the example of copper and brass to complete a summary passage which is differentiated so that those who need more assistance are still able to access the work. The remainder of the lesson focuses on steel and solder, again exploring how their different features are related to how they are used in modern day life. Progress checks have been written into the lesson at regular intervals to allow the students to check their understanding and a range of quick quiz competitions will aid engagement. This lesson has been designed for GCSE students but could be used with KS3 students who are looking at mixtures within the atoms and elements topic.

This lesson has been designed for GCSE students and looks at the key details of two methods that are used to make ethanol, fermentation and the hydration of ethene. Some students may believe that the sole use of ethanol is for alcoholic drinks so the first part of the lesson uses a quick competition to introduce some additional uses. There are a number of these competitions that run during the lesson, in order to maintain engagement but also to introduce key terms and check on understanding in alternative forms. The details of each of the reactions are discussed and related topics are tested through questions and tasks, such as the students being challenged to write symbol equations and adding state symbols and to remember the identification test for carbon dioxide. The final part of the lesson plays one final competition, which is a battle between all of the students to spot which of the two reactions is being described by a clue.

This is a fully-resourced lesson which includes an engaging and detailed lesson presentation and differentiated worksheets that together guide students through the key details of endothermic and exothermic reactions. This lesson has been designed for GCSE students but could be used with students entering this topic at A-level who are looking for a recap on the key details. This lesson focuses on a few critical areas of these reactions and those which are often poorly understood. For example, considerable time is taken to ensure that students understand how energy is taken in to break bonds in a reaction and given out when bonds are formed. From this basis, they learn to compare the amount of energy taken in with the amount given out and ultimately determine whether it is an endothermic or exothermic reaction. The format of the lesson is that students are guided through the combustion of methane as an exothermic reaction and shown how to draw reaction profiles and calculate energy changes using the bond energies to prove it is that type of reaction. Having worked with the teacher and each other on this reaction, students are then challenged to bring their skills together to describe, explain and represent an endothermic reaction. If students feel that they will need some assistance on this task, the worksheet has been differentiated so they can still access the learning. There are a number of quick competitions written into the lesson to maintain engagement and also progress checks are found at regular intervals so students can constantly assess their understanding. The lesson finishes with a final game called The E factor which tests the students knowledge from across the whole lesson.

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

A fully-resourced lesson which guides students through the method involved in calculating the empirical formula and includes a concise, clear lesson presentation (21 slides) and practice questions. Students are given a template to use as they are introduced to the questions and then encouraged to work without it as the lesson progresses. The students are shown how empirical formula questions can be made more difficult and hints are given so that students are able to tackle them and access all of the marks available. This lesson has been designed 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 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).
