Lessons

Chemical Sciences

  • Atomic Structure and the Periodic Table (free) — Describe atomic structure and the arrangement of the periodic table.
  • Chemical Reactions and Equations (free) — Represent chemical reactions using word and symbol equations.
  • Acids, Bases and pH — Classify substances as acids or bases and interpret pH data.
  • Rates of Reaction and Energy Changes — Use collision theory to explain factors affecting reaction rate, and classify reactions as exothermic or endothermic.

Biological Sciences

  • Cells and Body Systems (free) — Describe cell structure and how body systems work together to maintain life.
  • Homeostasis and Coordination (free) — Explain how the body maintains stable internal conditions using feedback mechanisms.
  • Genetics — DNA, Genes and Inheritance — Explain how traits are inherited through DNA, genes, and chromosomes.
  • Ecosystems and Energy Flow — Describe energy flow and matter cycling through ecosystems.

Physical and Earth Sciences

  • Waves — Sound and Light — Describe wave properties and distinguish between transverse and longitudinal waves.
  • Electricity — Circuits and Ohm's Law — Apply Ohm's Law and analyse series and parallel circuits.
  • Forces and Motion — Apply Newton's Laws and kinematic equations to describe and predict motion.
  • The Changing Earth and Climate Change — Explain plate tectonics, the greenhouse effect, and evidence for climate change.
  • Plate Tectonics — A Restless Earth — Describe the structure of the Earth, explain plate movement and boundaries, and evaluate evidence for plate tectonic theory.

Science Inquiry Skills

  • Scientific Investigation — Variables and Controls — Design and evaluate scientific investigations using appropriate methodology.
  • Evaluating Scientific Claims — Critically evaluate scientific evidence and distinguish science from pseudoscience.
