An informative lesson presentation (44 slides) that looks at the work of the key Scientists involved in the development of the atomic model. Dalton, Thomson, Rutherford and Bohr were four men whose work has led to the changes in the atomic model over the years and this lesson looks at parts of each of their work. There is a focus on Rutherford’s work with the alpha particles and students are challenged to draw conclusions based on the deflections they are shown. There is lots of time written into the lesson for consolidation and regular progress checks ensure that students have the opportunity to assess their understanding. This lesson has been written for GCSE students but could be used with KS3 students who perhaps are carrying out a project on the atom and want to add detail to their work

This is a fully-resourced revision lesson that uses a combination of exam questions, understanding checks, quick tasks and quiz competitions to help the students to assess their understanding of the sub-topics found within Topic C5 (Separate chemistry 1) of the Edexcel GCSE Chemistry specification.

A fully-resourced lesson which looks at the gaseous reversible reaction known as the Haber Process and then explores and explains why the specific conditions are chosen for this reaction. The lesson includes a detailed lesson presentation (29 slides) and associated worksheets which are differentiated. The lesson begins by challenging the students to use a description of the reaction to complete the balanced symbol equation. A quiz competition involving both Chemistry and Maths skills is used to reveal the temperature and pressure which are chosen for this reaction. Students will learn that this only produces a yield of 30% and therefore are encouraged to question why these conditions are chosen. In doing so, they are made to wear two “hats”, so that they consider it from both a Science angle but also a business angle. Their knowledge of reversible reactions and the effect of changing either the temperature or the pressure on the position of the equilibrium are constantly challenged and then checked through a range of progress check questions. As a result of this lesson, students will understand that these conditions are a compromise and be able to explain why. This lesson has been designed for GCSE students (14 - 16 year olds in the UK).

This is an engaging lesson that looks at a range of condensation polymers that are formed by condensation reactions. The lesson includes a detailed lesson presentation (51 slides) and accompanying worksheets which contain a differentiated task. The lesson begins by providing the students with a definition of a condensation reaction and challenging them to predict the identity of the smaller molecule. Moving forwards, students will learn that as well as water being a product, the larger molecule is known as a condensation polymer. Time is taken to look at a range of condensation polymers throughout the course of the lesson, and this includes both natural and artificial examples. Students are shown how to draw block diagrams to visualise how the functional groups react and then once water is removed, they are able to see the group that remains and joins the parts together. Students are shown how to name the ester formed according to the carboxylic acid and alcohol involved. The final part of the lesson involves a summary quiz called “It’s time to take the POLYGRAPH” where they have to read a number of passages about condensation polymers and decide which ones are telling lies and which are the truth. This lesson has been written for GCSE students

Moving forwards, students will be shown the next biological polymer that is a polypeptide. They are briefly shown how to draw a block diagram to represent the chain of amino acids. The final polymer are carbohydrates and students will learn how glycogen, starch and cellulose are formed from glucose monomers. Regular progress checks are written into the lesson at regular intervals to allow the students to check their understanding and ask questions. This lesson has been written for GCSE students
