This is a concise, fast-paced lesson that introduces students to addition polymers and guides them through drawing displayed formulae to represent both the monomers and polymers involved in these reactions. Students will learn the conditions needed for these reactions and that the polymers produced by addition reactions are the only products. The main part of the lesson involves a step by step guide to show students how to draw displayed formulae. Hints are given throughout the process so that students can remember the key ideas and are able to represent these substances accurately. A number of progress checks have been written into the lesson so that students can assess their understanding any misconceptions can be addressed. This lesson has been written for GCSE students

This revision resource has been designed with the simple aim of motivating the students whilst they assess their understanding of the content found in module 4.2.2 (Classification and evolution) of the OCR A-level Biology A specification. This module is often brushed over by students which leads to misconceptions and therefore time has been taken to explain the important concepts so that key points are recalled and retained. The resource includes a detailed and engaging Powerpoint (85 slides) and associated worksheets, some of which are differentiated to allow students of differing abilities to access the work. The range of activities have been designed to cover as much of the content as possible but the following sub-topics have been given particular attention: The biological classification of a species Classification hierarchy The three-domain and five-kingdom classification The features of the five kingdoms Phylogenetic trees Anatomical, physiological and behavioural adaptations Calculating the standard deviation Continuous and discontinuous variation In addition to these topics, some topics from other modules such as cell division and prokaryotic cells are tested in order to challenge the students on their ability to make links between the modules. The range of activities include exam questions and understanding checks as well as quiz competitions to maintain student engagement.

This revision resource has been designed to include a range of activities such as exam questions, understanding checks and quiz competitions which will motivate the students whilst they assess their understanding of the content found in module 2.1.4 (Enzymes) of the OCR A-level Biology A specification.

This clear and concise lesson explains how the inheritance of two or more genes that have loci on the same autosome demonstrates autosomal linkage. The engaging PowerPoint and associated resource have been designed to cover the part of point 6.1.2 (b[ii]) of the OCR A-level Biology A specification which states that students should be able to demonstrate and apply their knowledge and understanding of the use of phenotypic ratios to identify autosomal linkage. This is a topic which can cause confusion for students so time was taken in the design to split the concept into small chunks. There is a clear focus on how the number of original phenotypes and recombinants can be used to determine linkage and suggest how the loci of the two genes compare. Important links to other topics such as crossing over in meiosis are made to enable students to understand how the random formation of the chiasma determines whether new phenotypes will be seen in the offspring or not. Linkage is an important cause of variation and the difference between observed and expected results and this is emphasised on a number of occasions. The main task of the lesson acts as an understanding check where students are challenged to analyse a set of results involving the inheritance of the ABO blood group gene and the nail-patella syndrome gene to determine whether they have loci on the same chromosome and if so, how close their loci would appear to be. This lesson has been written to tie in with the other lessons from module 6.1.2 (Patterns of Inheritance)
