Economics COVER.jpg
Grade 12 Economics Lessons by Megan Little


In this podcast we will cover the definition of the 5 sectors (household, business, public, financial, foreign), explaining how sectors interact and explaining which markets they interact with (product and resource). At the end of this podcast you will be able to contextualize the 5 sectors through real world examples and understand how the 5 sectors interact in the economy. As well as understand how businesses exchange products for money in the product market, how household exchange factors of production in the resource market for money, how banks can ease money shortages and how we can interact with sectors in other countries.

In this podcast we will cover:

  • Defining 5 relevant sectors (household, business, public, financial, foreign)

  • Explaining how sectors interact

  • Explaining which markets they interact with (product and resource)


  • Circular Flow: Business turn factors prod into products and sell back to the businesses

  • Closed Economy: A closed economy is an economy in which no activity is conducted with outside economies. A closed economy is self-sufficient, meaning that no imports are brought in and no exports are sent out. The goal is to provide consumers with everything that they need from within the economy's borders.

  • Open Economy: A country will conduct trade with outside regions.

  • Factor Market: Markets where services of the factors of production (not the actual factors of production)are bought and sold

  • Product Market: The marketplace in which final goods or services are offered for purchase by consumers, businesses, and the public sector.

In this podcast we will cover exponents, the exponent laws and how these laws can be used to simplify more complex exponential problems.

In this podcast we will cover:

  • Real numbers
  • Non-real numbers


  • Natural numbers: 1, 2, 3, etc., are the numbers you might count with and do not include 0.

  • Whole numbers: The numbers {0, 1, 2, 3, ...} etc. There is no fractional or decimal part.

  • Integers: Negative numbers; -2, -1,

  • Rational numbers: All fractions where the decimal expansion terminates after a finite number of digits, or repeats the same finite number of digits over and over forever.

  • Irrational numbers: Those that cannot be written as a fraction.

  • Non-real numbers: Any negative number with an even root. These numbers are called non-real because they do not have real roots.

In this podcast we will cover the definition of an organic molecule, what makes carbon so special, the basic organic molecular chains and the various ways of representing them, the terms hydrocarbon and homologous series, various functional groups and the difference between a saturated and unsaturated compound.

In this podcast we will cover:

  • What makes carbon so special
  • Saturated and unsaturated compounds
  • Hydrocarbon and homologous series
  • Functional groups
  • Basic organic molecular chains
    • How to represent them


  • Organic Molecule: A molecule that contains carbon

  • Structural Formula: Shows all of the bonds in a molecule

  • Molecular Formula: Indicates the number of each different atom within the molecule

  • Hydrocarbon: A molecule containing only carbon and hydrogen atoms.

  • Homologous series: A group of compounds which can all be described by the same general formula

  • Functional group: An atom or group of atoms within a molecule which imparts special characteristics on the molecule in terms of activity or reactivity.

    • Alkene: A carbon bonded to another carbon by a double bond.

    • Alkyne: A carbon bonded to another carbon by a triple bond.

    • Alkl halides: Molecules containing a halogen atom in place of one or more hydrogen atoms within a hydrocarbon chain.

    • An alcohol: A molecule which contains an -OH group bonded to one of the carbon atoms.

    • Aldehyde: A molecule which contains an oxygen double bonded to a carbon at the end of a hydrocarbon chain.

    • Ketone: A molecule which contains an oxygen double bonded to a carbon in the middle of the hydrocarbon chain.

    • Carboxylic acid: A molecule in which one of the carbon atoms contains an -OH alcohol group and is bonded by a double bond to another oxygen.

    • Ester: A molecule which contains an oxygen within the back bone of a hydrocardon chain between 2 other carbons and one of those carbons is also bonded to another oxygen via a double bond.

  • Saturated compounds: All molecules containing only single bonds between carbon atoms.

  • Unsaturated compounds: All molecules containing double and triple bonds between carbon atoms.

In this podcast we will cover nucleic acids, the different types and the basic structure of nucleic acids.

In this podcast we will cover:

  • What are nucleic acids
  • Basic structure of nucleic acids
  • The Different types
    • RNA

    • DNA


  • Nucleic Acids: Are biological molecules that work together to make us who we are.

  • DNA: (Deoxyribonucleic acid) a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.

  • RNA: (Ribonucleic acid) a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

Grade 12 History by Debbie Orolowitz


In this podcast we will cover the context of African nationalism and decolonisation: the international and local factors that influenced Africa's decolonisation and the rise of nationalism.

In this podcast we will cover:

  • The context behind African nationalism and decolonisation
  • International and local factors that influenced Africa's decolonisation and the rise of nationalism
  • How independence was realised in Africa during the 1960s and 70s.


  • Decolonisation: When European colonial governments granted independence to the colony.

  • Nationalism: is the sense of belonging to a nation, according to a shared identity. This can be determined by background, geography, cultural, etc.

  • African Nationalism: is the desire for African people to rule themselves. This is also linked to identity.
