Course guides › Grade 8 › Natural Sciences
Grade 8 Natural Sciences goes deeper into the four CAPS strands: Life and Living, Matter and Materials, Energy and Change, and Planet Earth and Beyond. Investigations become more formal, with clear hypotheses, variables and conclusions.
This guide explains the four CAPS strands with key ideas and examples.
Course status: coming soon. We are still building the Grade 8 Natural Sciences (CAPS) course, so it can’t be bought yet. This guide explains what the CAPS curriculum covers this year, so you can use it now. The planned price is R300 per subject per year.
What’s covered: the four CAPS strands
The DBE’s Annual Teaching Plan sets the detailed topics and their order term by term, and your child’s school follows it. This guide gives the broad picture of each part of the subject.
Life and Living
Living things, how they work, and how they interact with each other and their environment.
Matter and Materials
What materials and substances are made of, their properties, and how they change.
Energy and Change
Forms of energy, how energy is transferred and used, and electricity.
Planet Earth and Beyond
The Earth, the Sun and the Moon, the Solar System and space.
Key ideas, with worked examples
Photosynthesis and respiration
Photosynthesis stores energy in sugar using light; respiration releases that energy in every living cell.
Worked example. carbon dioxide + water → (light) glucose + oxygen; glucose + oxygen → carbon dioxide + water + energy.
The particle model
All matter is made of tiny particles that are always moving; heating makes them move faster and spread out.
Worked example. A balloon left in the sun expands because the air particles inside move faster.
Series and parallel circuits
In series there is one path for the current; in parallel there are several.
Worked example. If one bulb in a series circuit blows, all go out; in a parallel circuit the others stay on, like the lights at home.
Common mistakes (and how to fix them)
- Thinking plants don’t respire.
- Confusing atoms and molecules.
- Mixing up series and parallel circuits.
- Thinking light needs a medium to travel.
Tips for parents
- Agree a routine, then step back. Senior Phase learners like to work on their own; check in on the week’s work rather than every page.
- Do safe kitchen chemistry: bicarbonate of soda and vinegar is a chemical reaction.
- Look at the night sky with a star-map app.
Frequently asked questions
How much will the Grade 8 Natural Sciences course cost?
R300 per subject per year once it opens. Like our live courses, it will be one course for the whole year with Terms 1 to 4 inside it, so there’s nothing extra to pay per term.
When will the course be ready?
We’re building it now. The Grade 8 Natural Sciences card on our home page shows “Coming soon” until the course is ready, and then it changes to “Open course”.
Will it work on a phone, and will it use a lot of data?
Yes, it will work on a phone. Like our live Maths courses, it will open in a phone’s web browser or in the free Coursebox app for Android and iPhone. Lessons are pictures and short text with quizzes and no videos, so it uses little data.
Is the course in English or Afrikaans?
The Grade 8 course will be in English.
Get ready for Grade 8 Natural Sciences
The Grade 8 Natural Sciences (CAPS) course is coming soon at R300 per subject per year. Bookmark this guide and use the overview above to follow what your child is doing at school. See which Grade 8 subjects are open on the course cards.
