Inside the grade 8 science lessons
The book starts with “how atoms join to make molecules” and the periodic table, moves through chemistry in “balancing equations and conserving atoms”, “measuring acidity with the pH scale” and “from crude oil to plastics and fibres”, and returns to physics with “resistance and how Ohm linked v, i and r”, “Newton's three laws of motion” and “reading motion graphs and acceleration”. Each of the 15 chapters begins with a quick answer, then explains the idea step by step with worked examples that always carry their units, and ends with key points to remember. Diagrams are used wherever a picture explains faster than a paragraph, and Lina adds a tip and a common mistake in every chapter. The final chapter, “fuels, nuclear power, renewables and the climate”, brings energy, fuels and the climate together, so the year ends with a question that matters outside the classroom.

Frequently asked questions
Who are the grade 8 science lessons for?
They suit readers aged 13 to 14 in grade 8, Year 9 or Class 8, ready to move on to separate physics and chemistry.
How is a chapter organised?
Each of the 15 chapters opens with a quick answer, explains the idea step by step with worked examples and diagrams, and ends with key points to remember, a common mistake to avoid, a tip from Lina and five frequently asked questions. Read from “how atoms join to make molecules” to “fuels, nuclear power, renewables and the climate”, or jump straight to “resistance and how Ohm linked v, i and r” if that is the topic you need.
What comes after the grade 8 science lessons?
The next step is the separate courses: physics grades 9-10 and chemistry grades 9-10.
How do I get the grade 8 science lessons?
Pay once with PayPal and the PDF is ready to download at once. It opens on up to 3 devices, so it can live on a laptop and a tablet.
