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 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.
