This lesson describes the characteristic features of the three domains and explains why viruses are not included in this classification. The PowerPoint and accompanying resources have been primarily designed to cover points 18.2 (b) & 18.2 (d) of the CIE A-level Biology specification but also contains tasks that challenge the students on their knowledge of taxonomic hierarchy from this topic and the features of virus from topic 1.
The lesson begins with an introduction of the microbiologist Carl Woese and goes on to describe how he is most famous for his definition of the Archaea as a new domain of life. Students were introduced to domains and the other classification taxa in the last lesson, so their recall of this knowledge is continually tested and built upon as details are added. Students will discover the key differences between Archaea and Bacteria that led to the splitting of the prokaryotae kingdom and the addition of this higher classification rank and will understand that it wasn’t until 13 years after the discovery that it was adopted. Moving forwards, the rest of the lesson explains why viruses are not included in this classification and outlines how they are classified, according to the ICTV, through the type of nucleic acid they contain and whether this is single-stranded or double-stranded

Topic 18: Biodiversity, classification and conservation (CIE A-level Biology)
Hours of research and planning has gone into each and every one of the 9 lessons that are included in this lesson bundle that covers topic 18 of the CIE A-level Biology course . Conscious that some students do not fully engage in the topics of biodiversity, classsification and conservation, the lessons have been designed to contain a wide range of tasks which will motivate the students whilst the content of the following specification points are covered: 18.1: Biodiversity * Define the terms species, ecosystem and niche * Explain that biodiversity can be considered at three different levels * Explain the importance of random sampling in determining the biodiversity of an area * Use suitable methods to assess the distribution and abundance of organisms in a local area * Use Spearman's rank correlation to analyse the relationship between the distribution and abundance of species and abiotic or biotic factors * Use Simpson's Index of diversity 18.2: Classification * Describe the classification of species into the 8 taxonomic divisions * Outline the characteristic features of the three domains * Outline the characteristic features of the kingdoms * Explain why viruses are not included in the three domain classification and outline how they are classified 18.3: Conservation * The reasons for the need to maintain biodiversity * Discuss methods of protecting endangered species * The role of non-governmental organisations like the WWF and CITES in local and global conservation If you would like to sample the quality of the lessons in this bundle, then download the Spearman's rank correlation, features of the kingdoms and WWF, CITES and conservation lesson as these have been uploaded for free

Topics 17 & 18: Selection, evolution, biodiversity & classification (CIE A-level Biology)
The topics of selection, evolution, biodiversity, classification and conservation are key concepts in Biology, that are regularly assessed in the exams, but are not always that well understood by the students. With this at the forefront of the lesson design, these 16 lesson PowerPoints and their accompanying resources have been intricately planned to cover the detailed content of topics 17 & 18 of the CIE A-level Biology specification through the use of a wide range of tasks to engage and motivate the students. There are plenty of opportunities for the students to assess their current understanding through the completion of exam-style questions and also to check on their prior knowledge by making links to earlier topics. The following specification points are covered by these lessons: Topic 17.1: Variation * The differences between continuous and discontinuous variation * Using the t-test to compare the variation of two different populations * The importance of genetic variation in selection Topic 17.2: Natural and artificial selection * Natural selection * Explain how environmental factors can act as stabilising, disruptive and directional forces of natural selection * Explain how the founder effect and genetic drift may affect allele frequencies in populations * Use the Hardy-Weinberg principle Topic 17.3: Evolution * The molecular evidence that reveals similarities between closely related organisms * Explain how speciation may occur Topic 18.1: Biodiversity * Define the terms species, ecosystem and niche * Explain that biodiversity is considered at three levels * Explain the importance of random sampling in determining the biodiversity of an area * Use suitable methods to assess the distribution and abundance of organisms in a local area * Use the Spearman's rank correlation to analyse relationships between data * Use Simpson's index of diversity Topic 18.2: Classification * The classification of species into taxonomic hierarchy * The characteristic features of the three domains * The characteristic features of the kingdoms * Explain why viruses are not included in the three domain classification Topic 18.3: Conservation * The reasons for the need to maintain biodiversity * Methods of protecting endangered species * The roles of organisations like the WWF and CITES in local and global conservation If you would like to sample the quality of the lessons that are included in this bundle then download the following as these have been shared for free: * Continuous and discontinuous variation * Molecular evidence & evolution * Spearman's rank correlation * WWF, CITES and conservation It is estimated that it will take up to 2 months of A-level Biology teaching time to cover the detail included in these lessons

Topic 18.2: Classification (CIE A-level Biology)
This lesson bundle contains 3 lessons which have been intricately planned to build on the knowledge acquired in the previous lesson and in earlier topics of the course to allow students to gain a deep understanding of classification. The lesson PowerPoints and accompanying resources contain a wide range of tasks which will engage and motivate the students whilst all of the content of topic 18.2 of the CIE A-level Biology specification is covered as detailed below: * Describe the classification of species into the taxonomic hierarchy of domain, kingdom, phylum, class, order, family, genus and species * The characteristic features of the three domains * The characteristic features of the kingdoms * The classification of viruses, separate to the three-domain model of classification of cellular organisms If you would like to sample the quality of the lessons in this bundle, then download the "features of the kingdoms" lesson as this has been shared for free
