How the grade 8 science worksheets work
The problems rise in difficulty and carry an easy, medium or hard label, and the last five on each sheet are the hardest, which is where students stretch beyond the lesson. On “balancing equations and conserving atoms” the student balances equations and counts atoms, on “power, energy and electricity bills” converts watts and kilowatt-hours into a bill, and on “reading motion graphs and acceleration” reads speed and acceleration from graphs. The answers do not stop at the result: they show the formula, the substitution and the unit, so that a student can compare a method with their own working. Use the book for homework, for cover lessons or for revision before the move to GCSE, IGCSE or high school physics and chemistry.

Frequently asked questions
Who are the grade 8 science worksheets 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. They work next to the lessons or next to any school textbook.
Where are the answers?
Part 2 gathers all the answers, after the 15 worksheets, so a student does not see an answer by accident. Each one shows the method, and the table of contents lists the answers of every chapter, from “how atoms join to make molecules” to “fuels, nuclear power, renewables and the climate”.
How many problems are on a worksheet?
Twenty, numbered Problem 1 to Problem 20 and sorted from easy to hard, each one marked easy, medium or hard. The sheet on “resistance and how Ohm linked v, i and r” has the same layout as all the others.
Can I print the grade 8 science worksheets?
Yes. Print the chapters you need, as many copies as you need for your own class or family. Payment is a single PayPal purchase with an instant download.
