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.

An engaging lesson presentation (46 slides) which looks at the fractional distillation of crude oil and focuses on the properties of the different fractions. The aim at the start of the lesson is to ensure that students understand that this process can be broken down into evaporation followed by condensation. Moving forwards, a fun competition is used to introduce the students to the names of some of the important fractions that are produced by this process. At the same time, they will learn the relative position that each fraction condenses on the fractionating column and will be taught that they need to know this position with relation to the other fractions. Students will learn that the fractions have differing properties depending on where they condense and they are challenged to compare fractions by viscosity, length of hydrocarbon and boiling point. 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.

This lesson explains the properties of typical covalent simple molecular compounds and introduces diamond and graphite as giant substances. The lesson PowerPoint and accompanying resource have been primarily designed to cover point 1.34 of the Edexcel GCSE Chemistry & Combined Science specifications but also links to points 1.35 - 1.37 where the structure and uses of the giant covalent substances are described. 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 is fully-resourced, engaging and detailed and explains how the Contact process is one of the 3 steps involved in making sulfuric acid. The PowerPoint and accompanying resources, which are differentiated, have been written to cover point C6.1(d) of the OCR Gateway A GCSE Chemistry specification. The lesson begins with a challenge where students have to use the 1st letters of the answers to questions on previously covered topics to come up with the word CONTACT. At this point, the students are introduced to the contact process as the 2nd step in a 3 stage process to make sulfuric acid. The lesson goes through the details of each of the 3 steps but particular time is spent exploring the conditions needed for the contact process in step 2. Students are continuously tested on their knowledge of reversible reactions and the key concepts to do with equilibrium position and equilibrium yield are explained so they can understand how the conditions of 2 atmospheres and 450 degrees celsius are chosen. Again through a prior knowledge check of empirical formula, the students will be introduced to vanadium oxide as the catalyst. As well as exam-style questions with displayed answers to check on current understanding, there are discussion points as well as quick quiz competitions to introduce key terms and values in a memorable way.

This lesson describes how the limiting reactant controls the mass of the product formed and explains how to deduce the stoichiometry. The PowerPoint and accompanying worksheet, which is differentiated, have been designed to cover points 1.52 & 1.53 of the Edexcel GCSE Chemistry specification and also covers those points in the Chemistry section of the Combined Science course. 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 is a fully-resourced lesson which looks at the properties of group 0 of the Periodic Table, the Noble Gases, and includes a lesson presentation (29 slides) and an associated worksheet. The lesson uses a range of engaging quiz competitions to enable the students to understand why these elements do not react. Other properties such as their boiling points are explored and there is continual reference to the other groups of elements so that students can make clear comparisons. This lesson has been designed for GCSE students (14 - 16 year olds in the UK), but it is also suitable for younger students who might be carrying out a project on the Periodic Table

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.
