A lesson on empirical formulas. It covers the method of finding an empirical formula by experiment, how to calculate the empirical formula from reacting masses and how to write a balanced equation from the reacting masses (this last topic is higher only). Designed for the Edexcel 9-1 spec.
A lesson covering the law of conservation of mass, reacting mass calculations (two methods are shown -- using moles and not using moles) and what a limiting reagent is (this last point is higher only). Includes exam questions for students to work through on the slides. Designed for the Edexcel 9-1 spec.
A lesson covering formulas and calculations - the lesson covers relative formula mass, definitions of empirical and molecular formulas, how to get an empirical formula from a molecular formula and how to calculate a molecular formula from an empirical formula and the relative formula mass.
Designed for the Edexcel 9-1 GCSE spec.
A introduction to electrolysis lesson covering key words (e.g. anode, cathode, oxidation, reduction, electrolyte, etc), how to predict the product of electrolysis of a molten salt and how the ions move during electrolysis. Designed for the Edexcel 9-1 Combined Science spec.
This lesson covers electrolysis of aqueous solutions - predicting the products and writing balanced half-equations. It includes a cart sort in which students match the salt, its ions and the products. Designed for the Edexcel 9-1 combined science spec.
A lesson covering the properties of ionic compounds designed for the Edexcel 9-1 spec. Includes the properties of ionic compounds, gap fills (on the Power Point) on explanations of the properties, exam questions on slides and a practical (students investigate the conductivity of salt solutions).
A lesson on the different forms of carbon - diamond, graphite, graphene and buckminster fullerene. Slides could be used to present lesson at the front or used as factsheets to allow students to design a poster on the different forms of carbon. Includes concise slides on each form of carbon, exam questions and links to videos. Designed for the Edexcel 9-1 specification.
A lesson covering the properties of simple covalent compounds designed for the Edexcel 9-1 spec. Covers the properties of covalent compounds, an explanation of why the compounds have these properties and a short practical. Slides also have exam questions for students to work through.
A lesson on covalent bonding designed for the Edexcel 9-1 spec. Covers what a covalent bond is, how to draw dot and cross diagrams and the size/scale of atoms & molecules. Includes exam questions (both Foundation and Higher) for students to work through on the slides. Designed for the Edexcel 9-1 spec.
A lesson on the electrolysis of copper sulfate and purification of copper. Covers the products of electrolysis of copper sulfate with copper and carbon electrodes, how to purify copper using electrolysis, and exam question and a practical on the electrolysis of copper sulfate (one part of the core practical). Designed for the Edexcel 9-1 combined science specification.
A lesson on covering what endothermic and exothermic mean, examples of each type of reaction and a practical in which students investigate the temperature changes of dissolving salts in water. Also includes slides with exam questions. Designed for Edexcel 9-1 combined science.
A lesson on cracking designed for the Edexcel 9-1 spec. The lesson covers what cracking is, why cracking is needed and the products of cracking. There are exam questions on the slides for students to complete. This presentation is for the combined science course and does not include detail from the separate sciences specification.
A lesson covering the causes of acid rain, the problems caused by acid rain and the advantages and disadvantages of using hydrogen fuel cells compared to petrol in cars. Slides with exam questions for the new spec are included. Designed for the Edexcel 9-1 combined science course --the triple only content on fuel cells is not included.
A lesson on what is a catalyst, how they speed up reactions and what an enzyme does (brief just includes what students need for the chemistry spec). Designed for the Edexcel 9-1 specification. Includes a practical that students can carry out.
A lesson covering endothermic and exothermic in terms of bonding breaking and making, drawing reaction diagrams and calculating overall energy changes from bond energy (higher only). Includes exam questions from the new spec. Designed for Edexcel 9-1 combined science. Includes higher only content.
