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.
