The Curriculum and Assessment Policy Statement (CAPS) for Engineering Graphics and Design outlines the nature and purpose of the subject Engineering Graphics and Design. This guides the philosophy underlying the teaching and assessment of the subject in Grade 12.
The purpose of these Examination Guidelines is to:

  • Provide clarity on the depth and scope of the content to be assessed in the Grade 12 National Senior Certificate (NSC) Examination in Engineering Graphics and Design.
  • Assist teachers to adequately prepare learners for the NSC examinations.

This document deals with the final Grade 12 external examinations. It does not deal in any depth with the School-based Assessment (SBA), Performance Assessment Tasks (PATs) or final external practical examinations as these are clarified in a separate PAT document which is updated annually.
These Examination Guidelines should be read in conjunction with:

  • The National Curriculum Statement (NCS) Curriculum and Assessment Policy Statement (CAPS): Engineering Graphics and Design
  • The National Protocol of Assessment: An addendum to the policy document, the National Senior Certificate: A qualification at Level 4 on the National Qualifications Framework (NQF), regarding the National Protocol for Assessment (Grades R–12)
  • The national policy pertaining to the programme and promotion requirements of the National Curriculum Statement, Grades R–12
  • Grade 12 Abridged CAPS Amendments to Section 4 (Implementation: January 2021)

There are three broad subject-specific aims in Life Sciences, which relate to the purposes of learning science, as shown below.

Specific Aim 1Relates to knowing the subject content
Specific Aim 2Relates to doing science or practical work and investigations
Specific Aim 3Relates to understanding the applications of Life Sciences in everyday life, as well as understanding the history of scientific discoveries and the relationship between indigenous knowledge and science

These specific aims are described in greater detail in the CAPS document (pages 13–18). It is important that these specific aims are addressed in both teaching and assessing.

Assessment in Grade 12 must cater for the differing abilities of learners by covering a range of cognitive levels and degrees of difficulty. These, together with the subject content, specific aims and range of skills, should be used to inform the planning and development of assessment tasks
The following weightings apply to assessment tasks set for Grade 12:

DAnalysis, Synthesis and Evaluation15


(Video) Life Sciences Exam Guide Paper 1

Easy for the average learner to answer.Moderately challenging for the average learner to answer.Difficult for the average learner to answer.Very difficult for the average learner to answer. The skills and knowledge required to answer the question allows for level 7 learners (extremely high-achieving/ability learners) to be discriminated from other high ability/
proficiency learners.

The framework for thinking about question/item difficulty comprises the following four general categories of difficulty:

  • Content (Topic/concept) difficulty
  • Stimulus (question and sources material) difficulty
  • Task (process) difficulty and
  • Expected response (memo) difficulty

Refer to the Grade 12 Abridged CAPS Amendments to Section 4 for the framework for thinking about question difficulty.
The following sequence of topics is recommended for teaching in Grade 12 based on the pro-gressive development of concepts through the different topics:

  1. DNA: The Code of Life
  2. Meiosis
  3. Reproduction in Vertebrates
  4. Human Reproduction
  5. Genetics and Inheritance
  6. Responding to the Environment (Humans)
  7. Endocrine System and Homeostasis in Humans
  8. Responding to the Environment (Plants)
  9. Evolution

Some changes have been made to the Programme of Assessment for Grade 12 from that which is specified on page 70 of the CAPS document. Refer to the Abridged Section 4 Amendments.
The examination will consist of two question papers of 2½ hours and 150 marks each.

IntroductionMention of Mendel as the 'father' of genetics
Concepts in
  • Chromatin and chromosomes
  • Genes and alleles
  • Dominant and recessive alleles
  • Phenotype and genotype
  • Homozygous and heterozygous
  • The Law of Dominance-
    • When two homozygous organisms with contrasting characteristics are crossed, all the individuals of the F1 generation will display the dominant trait
    • An individual that is heterozygous for a particular characteristic will have the dominant trait as the phenotype.
  • Format for representing a genetics cross
  • Mendel's Principle of Segregation –An organism possesses two 'factors' which separate or segregate so that each gamete contains only one of these 'factors'
  • Types of dominance:
    • Complete dominance – one allele is dominant and the other is recessive, such that the effect of the recessive allele is masked by the dominant allele in the heterozygous condition
    • Incomplete dominance – neither one of the two alleles of a gene is dominant over the other, resulting in an intermediate phenotype in the heterozygous condition
    • Co-dominance – both alleles of a gene are equally dominant whereby both alleles express themselves in the phenotype in the heterozygous condition
  • Genetics problems involving each of the three types of dominance
  • Proportion and ratio of genotypes and phenotypes
Sex determination
  • 22 pairs of chromosomes in humans are autosomes and one pair of chromosomes are sex chromosomes/gonosomes
  • Males have XY chromosomes and females have XX chromosomes
    • Differentiate between sex chromosomes (gonosomes) and autosomes in the karyotypes of human males and females
  • Representation of a genetic cross to show the inheritance of sex
  • Sex-linked alleles and sex-linked disorders
  • Genetics problems involving the following sex-linked disorders:
    • Haemophilia
    • Colour-blindness
Blood grouping
  • Different blood groups are a result of multiple alleles
  • The alleles IA, IB and i in different combinations result in four blood groups
  • Genetics problems involving the inheritance of blood type
Dihybrid crosses
  • Mendel's Principle of Independent Assortment – The various 'factors' controlling the different characteristics are separate entities, not influencing each other in any way, and sorting themselves out independently during gamete formation.
  • Dihybrid genetics problems
  • Determination of the proportion/ratio of genotypes and phenotypes
  • A genetic lineage/pedigree traces the inheritance of characteristics over many generations
  • Interpretation of pedigree diagrams
  • Definition of a mutation
  • Effects of mutations: harmful mutations, harmless mutations and useful mutations
  • Mutations contribute to genetic variation
  • Definition of gene mutation and chromosomal mutation
  • Two types of mutations that can alter characteristics leading to genetic disorders:
    Gene Mutations
  • Haemophilia – absence of blood-clotting factors
  • Colour-blindness – due to absence of the proteins that comprise either the red or green cones/photoreceptors in the eye
    Chromosomal mutation
  • Down syndrome – due to an extra copy of chromosome 21 as a result of non-disjunction during meiosis

    • Discontinuous variation – those characteristics that fall into distinct catego-ries e.g., blood groups
Origin of an idea about origins (a historical
Ideas on evolution in the order of their origin are as follows:
  • Lamarckism
  • Darwinism
  • Punctuated Equilibrium
(Jean Baptiste de Lamarck –
  • Lamarck used two 'laws' to explain evolution:
    • 'Law' of use and disuse
    • 'Law' of the inheritance of acquired characteristics
  • Reasons for Lamarck's theory being rejected
(Charles Darwin –1809–1882)
Darwin's theory of evolution by natural selection:
  • There is a great deal of variation amongst the offspring.
  • Some have favourable characteristics and some do not.
  • When there is a change in the environmental conditions or if there is competition,
  • then organisms with characteristics, which make them more suited, survive
  • whilst organisms with unfavourable characteristics, which make them less suited, die.
  • The organisms that survive, reproduce
  • and thus, pass on the allele for the favourable characteristic to their
  • The next generation will therefore have a higher proportion of individuals with the favourable characteristic.
(Eldredge and Gould – 1972)
  • Punctuated Equilibrium explains the speed at which evolution takes place:
  • Evolution involves long periods of time where species do not change or change gradually through natural selection (known as equilibrium).
  • This alternates with (is punctuated by) short periods of time where rapid changes occur through natural selection
  • during which new species may form in a short period of time.
Artificial selection

Artificial selection involving:

  • A domesticated animal species
  • A crop species
Formation of new species
  • Biological species concept: similar organisms that are capable of interbreeding to produce fertile offspring
  • Speciation and extinction and the effect of each on biodiversity
  • Speciation through geographic isolation:
    • If a population of a single species becomes separated by a geographical barrier (sea, river, mountain, lake)
    • then the population splits into two.
    • There is now no gene flow between the two populations.
    • Since each population may be exposed to different environmental conditions/the selection pressure may be different
    • natural selection occurs independently in each of the two populations
    • such that the individuals of the two populations become very different from each other
    • genotypically and phenotypically.
    • Even if the two populations were to mix again
    • they will not be able to interbreed.
    • The two populations are now different species.
  • Speciation through geographic isolation in ONE of the following:
    • Galapagos finches
    • Galapagos tortoises
    • Plants on different land masses (linked to continental drift)
      • Baobabs in Africa and Madagascar
      • Proteas in South Africa and Australia
    • Any example of mammals on different land masses
Mechanisms of reproductive isolation
(Keeping species separate)

A brief outline of reproductive isolation mechanisms that help to keep species separate:

  • Breeding at different times of the year
  • Species-specific courtship behaviour
  • Plant adaptation to different pollinators
  • Infertile offspring
  • Prevention of fertilisation
Evolution in present timesAny ONE example of natural selection and evolution in present times:
  • Use of insecticides and consequent resistance to insecticides in insects
  • Development of resistant strains of tuberculosis-causing bacteria (MDR and XDR) to antibiotics, due to mutations (variations) in bacteria and failure to complete antibiotic courses

    • Prognathism
    • Palate shape
    • Cranial ridges
    • Brow ridges
  • Lines of evidence that support the idea of common ancestors for living hominids including humans:
    • Fossil evidence: Evidence from fossils of different ages show that the anatomical characteristics of organisms changed gradually over time.
    • Emphasis on evolutionary trends provided by the anatomical features of fossils of the following three genera:
      • Ardipithecus
      • Australopithecus
      • Homo
        as well as:
      • The age of each fossil found/time-line for the existence of the three genera
      • The fossil sites where they were found: emphasis on the fossil sites that form a part of the Cradle of Humankind
      • The scientists who discovered them
    • Genetic evidence: mitochondrial DNA
    • Cultural evidence: tool-making
  • The Out-of-Africa hypothesis: Modern humans originated in Africa and then
    migrated to other continents
  • Evidence for the 'Out-of-Africa' hypothesis:
    • Fossil evidence: information on each of the following fossils that serve as evidence for the 'Out-of-Africa' hypothesis:
      • Ardipithecus (fossils found in Africa only)
      • Australopithecus (fossils found in Africa only, including Karabo, Little Foot, Taung Child, Mrs Ples)
