Revision Summary 11 Sci 2016 Science 1.1 Mechanics Content covered will include the following: Distance, speed, interpretation of distance and speed time graphs, average acceleration and deceleration in the context of everyday experiences such as journeys, sport, getting going. The relationships v = d v a . t t Mass, weight and the acceleration due to gravity, balanced and unbalanced forces, in the context of everyday experiences such as being stationary, moving at constant speed, accelerating. The relationship Fnet = ma. Force and pressure in the context of everyday experiences. The relationship P = Work and power, gravitational potential energy, kinetic energy, and the conservation of mechanical energy in free fall situations in the context of everyday experiences such as F . A sports performance, dropping things, tossing balls. The relationships EP = mgh EK = mv2 W = Fd P = 1 2 W . t Science 1.5 Acids and Bases Content covered will include: Atomic structure electron arrangement of atoms and monatomic ions of the first 20 elements (a periodic table will be provided) ionic bonding names and formulae of ionic compounds using a given table of ions. Properties acids release hydrogen ions in water reactions (of acids with bases) to form salts pH and effects on indicators. Rates of reaction and particle theory. Uses neutralisation carbon dioxide formation salt formation. Acids and bases are restricted to HCl, H2SO4, HNO3, metal oxides, hydroxides, carbonates and hydrogen carbonates. Other acids may be included in examination questions. The names and formulae of any such acids will be given in the question. Science 1.9 Genetic Variation Biological ideas relating to genetic variation are limited to concepts and processes connected with: the continuity of life based on the inheritable nature of DNA links between DNA and variation in phenotypes variation in phenotypes as adaptive features. Biological concepts and processes relating to the inheritable nature of DNA will be selected from: the roles of DNA in both carrying instructions to the next generation and determining phenotype the relationship between DNA, alleles, genes, and chromosomes the way in which genotype determines phenotype the way chromosomes exist as pairs so that individuals inherit two copies of each gene. Biological concepts and processes relating to variation in phenotype will be selected from: the significance of an allele as an alternative version of a gene the role of mutations in forming new alleles the role of meiosis in generating gametes (students are not required to provide the names of the stages of meiosis) the significance of sexual reproduction (in producing a new mix of alleles) the patterns of inheritance involving simple monohybrid inheritance showing complete dominance, sex determination, possible genotypes, and phenotype ratios. Biological concepts and processes relating to variation in phenotypes as adaptive features will be selected from: inheritable and non-inheritable variations that exist within a group of living organisms differing rates of survival by various members of a group may depend on their phenotype the importance of variation within populations (population and species survival) in a changing environment such as pest infestation, disease, drought, or flood the advantages and disadvantages of sexual reproduction. The student must be familiar with the following genetic language and conventions: gene, allele, mutation, genotype, phenotype, gamete, zygote, dominant, recessive, homozygous, heterozygous, pure breeding, Punnett square, and pedigree chart. How to Revise: The methods and timing of your revision will need to be what best suits you. Make sure you use a range of different revision methods and regularly complete questions and mark them to make sure you are making progress. Ways you can revise: Concept maps Put a central theme of a topic in the middle of a clean page and then add supporting ideas around it in an organised way. Use notes as well as images and colour. You are aiming to produce a visual resource that you can close your eyes and recall in the exam. Don’t be tempted to overload one concept map. If it is getting too busy, break the topic into smaller parts and do separate maps for each part. Topic workbooks. These are organised into small chunks of each topic. Check the contents list at the front of your workbook and focus on one section at a time. Read the notes in the workbook, read the relevant notes you made in class, attempt the questions. Complete the revision questions at the end of each section. Don’t forget to mark your work to make sure you are on the right track. Use the checklists at the front of the workbook to ensure you are confident in all areas of the standard. Flashcards. Do not underestimate the power of being able to recall definitions and key ideas from memory easily. Use flash cards for the following: Mechanics: Formula, units and definitions Acids and Bases: Definitions, Symbols and formula for key chemicals (HCL, H2SO4, HNO3, CaCo3….) Atomic Theory atomic mass…. Definitions: pats of an atom, ions, electron configuration, atomic number, Patterns of reactions – acid + metal Acid + metal oxide (metal hydroxide) Acid + metal carbonate (metal hydrogen carbonate) Neutralisation reactions Rates of reactions: Effect of each of Surface area, temperature, concentration, catalyst and how impacts on collisions and hence reaction rate Genetics: Definitions from glossary lists on pg 72 and 73 of the workbook Past papers. All previous NCEA exam papers and their marking schedules are available online. Once you are confident that you know the topic, print out a paper and have a go under test conditions. Set aside 1 hour with no distractions and attempt a full paper. Make sure you mark your work and identify the areas you need to work on. Work on those areas and then try a different paper.
