Secondary 4 science
In Secondary 4, students learn how DNA and genes carry inherited information and how natural selection drives evolution. They use the periodic table to explain patterns in elements, investigate factors that affect reaction rates, explore the evidence for the Big Bang and Earth's global systems, and use Newton's laws to describe and predict motion. Investigations become more independent, with attention to error and uncertainty.
Awaiting educator review. This material was drafted by our content team with AI assistance and is waiting for review by a qualified educator. Please check it suits your child before using it. Created 10 October 2026. How we review
Biological sciences
- DNA, genes and inheritanceTopic outlineStudents describe the structure of DNA, how genes code for proteins, and use Punnett squares to predict simple patterns of inheritance.
- Evolution by natural selectionTopic outlineStudents explain natural selection using variation, inheritance and differential survival, with evidence from fossils, comparative anatomy, DNA and Australia's unique marsupials.
Chemical sciences
- The periodic tableTopic outlineStudents explain how the periodic table is organised by atomic number and electron arrangement, and use groups and periods to predict properties.
- Rates of reactionFull lesson · 60 minStudents use collision theory to explain how temperature, surface area, concentration and catalysts affect how fast reactions happen, testing effervescent tablets at home.
Earth and space sciences
- The universe and the Big BangTopic outlineStudents describe the structure of the universe and the evidence for the Big Bang theory, including red shift and cosmic microwave background radiation, and Australia's role in radio astronomy.
- Global systems and climateTopic outlineStudents explain how the carbon cycle links the atmosphere, oceans, land and living things, and evaluate evidence for climate change and its effects in Australia.

Curriculum notes
Australian Curriculum v9.0. Topics are organised around the Australian Curriculum v9.0 Science strands and sub-strands. This is an independent learning resource; it is not endorsed by ACARA and has not been mapped to individual content descriptions.
These lessons were written around Australian Curriculum strands and matched to Singapore levels by age (Primary 1 is the first year of primary school). They are not aligned to MOE syllabuses or the PSLE, so check them against the syllabus your child is working towards.
