GCE AS Level Biology notes written for the AQA specification Biology (2410). The topics covered in the revision guide are detailed here: Unit 2 3.2.1 Living organisms vary and this variation is influenced by genetic and environmental factors. Investigating variation Causes of variation 3.2.2 DNA is an information-carrying molecule. Its sequence of bases determines the structure of proteins, including enzymes. Structure of DNA Genes and polypeptides DNA and chromosomes Meiosis 3.2.3 Similarities and differences in DNA result in genetic diversity. Genetic diversity 3.2.4 The variety of life is extensive and this is reflected in similarities and differences in its biochemical basis and cellular organisation. Haemoglobin Carbohydrates Cells 3.2.5 During the cell cycle, genetic information is copied and passed to genetically identical daughter cells. Replication of DNA Mitosis Cell cycle 3.2.6 In complex multicellular organisms, cells are organised into tissues, tissues into organs and organs into systems. Cell differentiation 3.2.7 Factors such as size and metabolic rate affect the requirements of organisms and this gives rise to adaptations such as specialised exchange surfaces and mass transport systems. Size and surface area Gas exchange Mass transport The blood system The passage of water through a plant 3.2.8 Classification is a means of organising the variety of life based on relationships between organisms and is built round the concept of species. Principles of taxonomy 3.2.9 Originally, classification systems were based on observable features but more recent approaches draw on a wider range of evidence to clarify relationships between organisms. Genetic comparisons DNA Proteins Behaviour 3.2.10 Adaptation and selection are major components of evolution and make a significant contribution to the diversity of living organisms. Antibiotics Genetic variation in bacteria 3.2.11 Biodiversity may be measured within a habitat. Species diversity Index of diversity

A great plan for variables in computing. TESPlan.docx gives a lesson plan that guides you through the following: - VariablesTES is the main presentation to explain variables. - Data types variables introduces data types and has an exercise for students to complete (worksheet is VariablesDataTypes - Code Scramble has questions for off computer work related to variables - VariablesProgrammingTask has a set of questions (not programming language dependent) for students to complete This lesson is not dependent on a particular programming language. It is a set of activities and a presentation to help students with this important concept in computing.

Full lesson around the natural world. Contains presentation (look at presenter notes for more information) and worksheet that the students complete in groups before feeding back to the class.
