Core KS3 science topics and why they matter later
| Science | Key KS3 topics | Leads to at IGCSE or GCSE |
|---|---|---|
| Biology | Cells and microscopes, body systems, nutrition and digestion, photosynthesis, respiration, ecosystems, inheritance | Cell biology, transport, enzymes, genetics |
| Chemistry | Particle model, atoms, elements and compounds, mixtures and separation, acids and alkalis, reactions, the periodic table | Atomic structure, bonding, moles, rates |
| Physics | Energy, forces and motion, speed, pressure, waves, light and sound, electricity and magnetism, space | Equations and calculations, circuits, waves |
| Working scientifically | Variables, fair tests, tables and graphs, evaluating methods | Required or core practicals and data questions |
Topics from England's KS3 science programme of study and Cambridge Lower Secondary Science strands. Order varies by school.
How KS3 science is assessed
England has no national KS3 science test, so Gulf British schools use end-of-unit and end-of-year tests, and some use external benchmarks such as GL Assessment's Progress Test in Science. Schools following Cambridge Lower Secondary may enter students for Checkpoint Science at the end of Stage 9. Results are reported on a 0 to 50 scale with six performance bands, and from 2026 tests run in March, May and October.
KS3 results also feed decisions about Year 10: whether a student studies the three sciences separately or a combined or co-ordinated course, and later which tier they sit. Many Gulf schools start IGCSE science content in Year 9.
What KS3 students find hard
- Using the particle model to explain melting, dissolving and diffusion, rather than describing what is seen.
- Science maths: rearranging speed = distance / time, unit conversions, and plotting graphs with sensible scales.
- Identifying independent, dependent and control variables in an investigation.
- Writing equations for reactions, even in words, and later with symbols.
- Linking body systems: how digestion, breathing and circulation work together to deliver energy.
- Learning precise vocabulary, especially for students taught science in Arabic before joining a British school.
How one-to-one KS3 science lessons work
The tutor starts with a short diagnostic across the three sciences and a look at recent school tests. Lessons follow the topic your child is studying in class, so each session helps with this week's work, while the tutor fixes underlying ideas such as particles or energy that keep coming up. Diagrams and simple simulations on the shared whiteboard make abstract ideas visible, and each lesson includes a few exam-style questions to practise explaining clearly.
Starting in Year 7 or 8 means problems are fixed while the content is still gentle. In Year 9, lessons can also prepare for Checkpoint or for the move to IGCSE sciences. Parents see lessons and progress notes in the parent account.
Common questions
Is KS3 science one subject or three?
Most schools teach it as one subject with biology, chemistry and physics units, sometimes with specialist teachers. It splits into separate or combined courses at IGCSE or GCSE.
What is Cambridge Checkpoint Science?
An optional test at the end of Stage 9 covering the Cambridge Lower Secondary Science framework. Scores run from 0 to 50 with performance bands from Basic to Outstanding.
My child switched from a national curriculum school. Can a tutor help?
Yes. A tutor can map what has already been covered, teach the English scientific vocabulary, and close gaps before IGCSE starts.
Does one tutor cover all three sciences?
At KS3, yes. We match a tutor who teaches general science at this level.
What do KS3 science lessons cost?
$15 a lesson, the same for every subject. Lessons are one to one, 60 minutes, on a weekly plan of 1 to 5 lessons billed monthly. The first lesson is a free trial.
