A detailed lesson which includes a lesson presentation (52 slides) and an associated worksheet that goes through the basis of electrolysis and then focuses on the examples when the electrolyte is a molten salt. The lesson has been designed to move in small steps with regular progress checks so that key details are fully understood. It begins by ensuring that students understand which ions are attracted to which electrode. The lesson then looks at how electrons are either gained or lost at the electrodes and this is related to redox reactions as well. Helpful hints and exam question tips are given throughout to aid students with this commonly assessed topic. This lesson has been designed for GCSE students (14 - 16 year olds in the UK) but could be used with both older and younger students

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)

A fully-resourced lesson which guides students through drawing, writing and recognising the electronic configurations of atoms and ions. The lesson includes an engaging lesson presentation (33 slides), an associated worksheet and a competition worksheet. The lesson begins by introducing the students to the number of electrons that can be held on the first three electron shells. They are then shown how to draw an electronic configuration and write this in brackets form. Students are given the opportunity to apply this knowledge by drawing the configuration of first 20 elements of the Periodic Table. Moving forwards, students are guided to enable them to discover how the electron configuration is linked to the position of an atom in the Periodic Table. The remainder of the lesson focuses on ions and how the configuration of these substances can be recognised. Some time is taken to explain how ions are formed from atoms and the lesson finishes with a competition which challenges students to identify atoms or ions from their configurations to form a word. There are regular progress checks throughout the lesson to allow the students to check on their understanding and a range of quiz competitions to maintain engagement. This lesson has been written for GCSE students but could be used with younger students, especially the initial part of the lesson on atoms and the link to the Periodic Table

A concise lesson presentation (21 slides) which uses a range of methods to allow students to discover how to draw dot and cross diagrams for covalent structures. The lesson begins by challenging the students to recall their knowledge of electronic structure to show the outer shell of two specified atoms. They will then see how it is possible for both of these atoms to get full outer shells by sharing as happens in this type of bonding. A few more examples are used to consolidate this understanding before quick competition is used to check the understanding so far. Moving forwards, a step by step guide shows students how to draw dot and cross diagrams using the same techniques as was utilised with the hulas. This lesson has been written for GCSE students but could be used with higher ability KS3 students.

A fully-resourced lesson that looks at a number of the allotropes of carbon which need to be known for GCSE Science. The lesson includes an engaging lesson presentation (40 slides) and associated worksheets. The lesson begins by recalling the definition of an allotrope. Students are then introduced to graphene and will understand how this is related to graphite and know the properties of these two materials that are shared. Time is taken to ensure that students can explain why graphene is able to conduct electricity. Moving forwards, students will meet the family of allotropes known as the fullerenes and will see some important details about a few of these. This lesson has been written for students studying GCSE (14 - 16 year olds in the UK).

A fully-resourced lesson which looks at the meaning of the rate of reaction and guides students through calculating both the mean and instantaneous rate of reaction. The lesson includes a concise lesson presentation (19 slides) and a question worksheet which is differentiated two ways. The lesson begins by challenging the students to suggest the missing factor in the rate of reaction equation so they can learn that either the mass of a reactant or a mass of a product could be used. Links are made to practical skills as students will understand that if a product is in the gaseous form, the volume produced within a set time will enable the rate to be calculated. Worked examples are used to show the students how to calculate the mean rate of reaction and then the instantaneous using a tangent. The rest of the lesson involves collecting data from an experiment to calculate the rate of reaction. The questions associated with the practical have been differentiated so students who need assistance can still access the learning. This lesson has been written for GCSE students

This concise lesson presentation (20 slides) guides students through the effect of changing pressure on the position of the equilibrium. The key skill to this topic involves recalling the rule of increasing pressure and being able to recognise how many moles are on each side of the reaction. For this reason, time is taken to remind the students of the meaning of the mole numbers in a reaction and working through an example together so they can see which side will be favoured. The final part of the lesson involves a game called “The PRESSURE is on” where students are in a race against the clock to balance an equation and then work out which way the equilibrium will shift when either the pressure is increased or decreased. 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

This lesson has been written with the aim of engaging students in the topic of simple and giant covalent molecules, as this is a topic which is often considered to be boring or is brushed over. A variety of tasks have been used to maintain the interest whilst ensuring that they key details and Science are known and understood. The lesson begins with a quick recap task where students have to recognise a covalent bond from a description and fill the missing part. Moving forwards, they are introduced to the fact that covalent molecules can be simple or giant. They are then presented with a table showing some properties of covalent molecules and having to group them as simple or giant in the short space of time that the table remains displayed on the board. This task challenges their observational skills, something which will again be tested later in the lesson as they study the structure of graphite and diamond. Time is taken to ensure that key details such as the strong covalent bonds in both sets of molecules is understood and that it is the weak intermolecular forces which are actually responsible for the low melting and boiling points. The last part of the lesson introduces diamond and graphite as allotropes of carbon and students will briefly learn why one of these conducts electricity whilst the other doesn’t. If you want a lesson about these allotropes in more detail, then please look for “Diamond and Graphite”. Progress checks have been written into the lesson at regular intervals so that students are constantly assessing their understanding and so misconceptions are quickly identified. This lesson has been written for GCSE students (14 - 16 years of age in the UK)
