Every one of the lessons included in this bundle is detailed, engaging and fully-resourced, and has been written to cover the content as detailed in topic 4 of the AQA A-level Biology specification. The wide range of activities will maintain engagement whilst supporting the explanations of the content to allow the students to build a deep understanding of genetic information, variation and relationships between organisms. The following 18 lessons covering the 7 sub-topics are included in this bundle: 4.1: DNA, genes and chromosomes DNA in prokaryotes and eukaryotes Genes 4.2: DNA and protein synthesis Genome, proteome and the structure of RNA Transcription and splicing Translation 4.3: Genetic diversity can arise as a result of mutation or during meiosis The genetic code Gene mutations Chromosome mutations Meiosis 4.4: Genetic diversity and adaptation Genetic diversity Natural selection Directional and stabilising selection Adaptations 4.5: Species and taxonomy Species and taxonomy 4.6: Biodiversity within a community Biodiversity within a community Calculating an index of diversity The balance between conservation and farming 4.7: Investigating diversity Investigating diversity Interpreting mean values and the standard deviation If you would like to sample the quality of the lessons in this bundle, then download the DNA in prokaryotes and eukaryotes, structure of RNA, gene mutations, natural selection and standard deviation lessons as these have been uploaded for free

Hours and hours of planning have gone into each and every lesson that’s included in this bundle to ensure that the students are engaged and motivated whilst the detailed content of topic 2 of the Edexcel International A-level Biology specification is covered. Membranes, proteins, DNA and gene expression represent some of the most important structures, molecules and processes involved in this subject and a deep understanding of their role in living organisms is important for a student’s success. The 20 lesson PowerPoints and accompanying resources contain a wide range of activities which cover the following topic 2 specification points: Know the properties of gas exchange surfaces in living organisms Understand how the rate of diffusion can be calculated using Fick’s Law of Diffusion Understand how the structure of the mammalian lung is adapted for rapid gas exchange The structure and properties of cell membranes The movement of free water molecules by osmosis The movement across membranes by passive and active transport The role of channel and carrier proteins in membrane transport The basic structure of an amino acid The formation of polypeptides and proteins The structure of proteins The mechanism of action and specificity of enzymes Enzymes are biological catalysts Intracellular and extracellular enzymes The basic structure of mononucleotides The structure of DNA and RNA The process of DNA replication The nature of the genetic code A gene as a sequence of bases on DNA that codes for a sequence of amino acids The process of transcription and translation Errors in DNA replication give rise to mutations Mutations give rise to disorders but many mutations have no observable effect The meaning of key genetic terms Understanding the pattern of monohybrid inheritance Sex linkage on the X chromosome Understand how the expression of a gene mutation in people with cystic fibrosis impairs the functioning of the gaseous exchange, digestive and reproductive systems The uses and implications of genetic screening and prenatal testing Due to the detail included in all of these lessons, it is estimated that it will take in excess of 2 months of allocated A-level teaching time to complete the teaching of the bundle If you would like to sample the quality of these lessons, then download the rapid gas exchange, osmosis, DNA & RNA, genetic code, genetic terms and cystic fibrosis lessons as these have been uploaded for free.

This bundle of 19 lessons covers the majority of the content in Topic B6 (Global challenges) of the OCR Gateway A GCSE Biology specification. The topics covered within these lessons include: Investigating distribution by sampling Increasing biodiversity Loss of biodiversity Selective breeding Genetic engineering Producing a GMO Health and disease Communicable diseases Stopping the spread of diseases Plant diseases Plant defences The Human Body’s Defences Blood clotting The uses of vaccines Monoclonal antibodies Antibiotics Developing drugs Non-communicable diseases Treating cardiovascular diseases Organ transplants Stem cells in medicine All of these lesson presentations and accompanying resources are detailed and engaging and contain regular progress checks to allow the students to constantly assess their understanding.

This bundle of 17 lessons covers the majority of the content in Topic B6 (Global challenges) of the OCR Gateway A GCSE Combined Science specification. The topics covered within these lessons include: Investigating distribution by sampling Increasing biodiversity Loss of biodiversity Selective breeding Genetic engineering Producing a GMO Health and disease Communicable diseases Stopping the spread of diseases Plant diseases The Human Body Defences Blood clotting Using vaccines In the prevention of disease Antibiotics Developing drugs Non-communicable diseases Treating cardiovascular diseases Organ transplants Stem cells in medicine All of these lesson presentations and accompanying resources are detailed and engaging and contain regular progress checks to allow the students to constantly assess their understanding.

This bundle contains 19 fully-resourced and detailed lessons that have been designed to cover the content of topic 6 of the AQA A-level Biology specification which concerns the responses of organisms to stimuli. The wide range of activities included in each lesson will engage the students whilst the detailed content is covered and the understanding and prior knowledge checks allow them to assess their progress on the current topic as well as challenging them to make links to other related topics. Most of the tasks are differentiated to allow differing abilities to access the work and be challenged. The following sub-topics are covered in this bundle of lessons: Survival and response in flowering plants The role of sensory receptors as outlined by the Pacinian corpuscle The human retina as a sensory receptor The differences in rods and cones that enable different sensitivity to light, colour and visual acuity The roles of the SAN, AVN, Bundle of His and Purkyne fibres in the conduction system of the heart The control of heart rate The structure of a myelinated motor neurone The factors that affect the speed of conduction of an impulse The generation and transmission of nerve impulses The transmission at a cholinergic synapse and a neuromuscular junction Summation The contraction of skeletal muscles The structure and properties of slow and fast skeletal muscle fibres The principles of homeostasis including negative feedback systems The control of blood glucose concentration by the controlled release of insulin and glucagon The causes and control of diabetes type I and II The gross structure of the kidney The detailed structure of the nephron The production of glomerular filtrate The reabsorption of glucose and water in the PCT Maintaining a gradient of sodium ions in the medulla by the loop of Henle The role of the hypothalamus, posterior pituitary and ADH in osmoregulation This is one of the 8 topics which have to be covered over the length of the 2 year course and therefore it is expected that the teaching time for this bundle will be in excess of 2 months If you want to see the quality of the lessons before purchasing then the lessons on responses in flowering plants, saltatory conduction, the contraction of skeletal muscles and ultrafiltration are free resources to download
