Stuck with your tutor group for an extra hour because...reasons...? Have a last lesson planned, run it and the students love it. Then suddenly Christmas lunch is cancelled and you see the same group again? Students demand that you have a 'fun' lesson but you just...well...didn't plan it? Here is a set of ideas that are just pick up and go. Really. Just give yourself 5 minutes before the lesson and have a Merry Christmas one and all.

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

GCE AS Level Biology notes written for the AQA specification Biology (2410). The topics covered in the revision guide are detailed here: Unit 1 3.1.1 Disease may be caused by infectious pathogens or may reflect the effects of lifestyle Pathogens Lifestyle 3.1.2 The digestive system provides an interface with the environment. Digestion involves enzymic hydrolysis producing smaller molecules that can be absorbed and assimilated. The Digestive system Proteins Enzyme action Enzyme properties Carbohydrate digestion 3.1.3 Substances are exchanged between organisms and their environment by passive or active transport across exchange surfaces. The structure of plasma membranes enables control of the passage of substances across exchange surfaces. Cells Plasma membranes Diffusion Osmosis Active transport Absorption Cholera 3.1.4 The lungs of a mammal act as an interface with the environment. Lung function may be affected by pathogens and by factors relating to lifestyle. Lung function The biological basis of lung disease 3.1.5 The functioning of the heart plays a central role in the circulation of blood and relates to the level of activity of an individual. Heart disease may be linked to factors affecting lifestyle. Heart structure and function The biological basis of heart disease 3.1.6 Mammalian blood possesses a number of defensive functions. Principles of immunology

GCE A Level Biology notes written for the AQA specification Biology (2410). The topics covered in the revision guide are detailed here: Unit 5 3.5.1 Stimuli, both internal and external, are detected and lead to a response. 3.5.2 Coordination may be chemical or electrical in nature. 3.5.3 Skeletal muscles are stimulated to contract by nerves and act as effectors. 3.5.4 Homeostasis is the maintenance of a constant internal environment. 3.5.5 Negative feedback helps maintain an optimal internal state in the context of a dynamic equilibrium. Positive feedback also occurs. 3.5.6 The sequence of bases in DNA determines the structure of proteins, including enzymes. 3.5.7 Gene expression is controlled by a number of features. 3.5.8 Gene cloning technologies allow study and alteration of gene function in order to better understand organism function and to design new industrial and medical processes.

GCE A Level Biology notes written for the AQA specification Biology (2410). The topics covered in the revision guide are detailed here: Unit 4 3.4.1 The dynamic equilibrium of populations is affected by a number of factors. 3.4.2 ATP provides the immediate source of energy for biological processes. 3.4.3 In photosynthesis, energy is transferred to ATP in the light-dependent reaction and the ATP is utilised in the light-independent reaction. 3.4.4 In respiration, glycolysis takes place in the cytoplasm and the remaining steps in the mitochondria. ATP synthesis is associated with the electron transfer chain in the membranes of mitochondria. 3.4.5 Energy is transferred through ecosystems and the efficiency of transfer can be measured. 3.4.6 Chemical elements are recycled in ecosystems. Microorganisms play a key role in recycling these elements. 3.4.7 Ecosystems are dynamic systems, usually moving from colonisation to climax communities in the process of succession. 3.4.8 Genetic variation within a species and geographic isolation lead to the accumulation of different genetic information in populations and the potential formation of new species.
