If you’re considering the Cambridge Checkpoint Science series for your Key Stage 3 students, this guide takes you through the complete curriculum journey from Stage 7 through to Stage 9. I’ve designed these books to engage students with science whilst building the foundations of scientific literacy they’ll need for IGCSE and beyond.
Let me walk you through what each stage offers and how the series develops key scientific concepts across the three years.
Stage 7 (stage 6 in Pakistan)
The Earth in Space
The journey begins with The Earth in Space, where students explore gravity’s crucial role in planet formation before moving on to our solar system’s formation and structure. I’ve included contemporary content on interstellar objects that have made passing visits to our system – something that really captures students’ imagination.
The chapter delves into the relationship between tides and the positions of the Sun and Moon, explains the phases of the Moon in detail, and concludes with solar and lunar eclipses. These are topics that students can observe in their own lives, which helps them connect classroom learning to the world around them.
A Closer Look at the Earth
The second chapter examines Earth’s internal structure in detail before moving on to tectonic plates and the dramatic consequences of their movements – mountain formation, volcanoes and earthquakes. Students compare the Mercalli intensity scale with the Richter magnitude scale using internet research, then participate in an enquiry about what we can learn from studying vibrations.
The study of Earth’s atmosphere follows, beginning with how our atmosphere is changing with a focus on air pollution. We then explore water movement through the water cycle and examine what happens to water once it reaches the ground. This foundation proves essential for understanding the environmental challenges students will encounter in later stages.
Stage 8 (Stage 7 in Pakistan)
Using Earth’s Resources
Building on Stage 7’s closer look at Earth, this chapter examines renewable material resources like bioplastics alongside non-renewable resources such as metal ores and minerals. Students then explore renewable energy resources – wind, river water, tides, waves and solar energy.
The study of non-renewable energy sources, the fossil fuels, is set in a historical context that considers our impact on ecosystems. The chapter concludes by examining Ecosystem Impact Ratings of our activities as we spread across the planet. This helps students understand both the science and the consequences of human resource use.
The Earth’s Climate
This chapter begins by distinguishing between weather and climate – a vital distinction that many students (and adults!) struggle with. We then move on to collecting data on Earth’s climate, examining different world climates, and investigating evidence for past climate change through fossils, pollen grains and ice cores.
Inside a Galaxy
The final Stage 8 chapter starts with a hands-on activity – making a model of the Milky Way galaxy in a coffee cup! From there, students explore different types of galaxies before venturing into intergalactic space to consider stellar dust.
Cloud formation in galaxies follows, with a comparison of our solar system to four Kepler planetary systems. The chapter finishes with asteroids, including an image of an asteroid with its own moon – always a talking point in the classroom!
Stage 9 (Stage 8 in Pakistan)
Planet Earth
The final stage begins by examining how ideas about Earth have changed over time. Students evaluate evidence from tectonic plates, rock types, ocean research, fossils, volcanoes, earthquakes and magnetism. The chapter ends with a more detailed look at how tectonic plates actually move – building on the foundation from Stage 7.
Cycles on Earth
Nothing around us stays the same for long, and this chapter examines the carbon cycle in detail through its key processes: photosynthesis, respiration, feeding, decomposition and combustion. This naturally leads to carbon dioxide as a greenhouse gas, followed by data showing climate change and its effects – sea level change, extra water in the atmosphere and extreme weather events.
These are topics that will shape your students’ futures, and I’ve tried to present them in a way that’s scientifically rigorous whilst remaining accessible and engaging.
Earth in Space
The final chapter takes one last look at our planet, beginning with asteroids and the effects of their collisions. Students examine evidence for how the Moon formed before exploring stellar nurseries – the birthplaces of stars.
The chapter concludes by looking at astronomy across the world, with encouragement to use the internet sensibly to discover the latest findings about exoplanets, dark matter and dark energy. I want students to understand that science is an ongoing adventure, not a closed book.
Science Today and Tomorrow: Bringing It All Together
Throughout my teaching career, I’ve tried to engage with students in a way that sparks their interest. I began at the start of Stage 7 by asking them what kind of scientist they might like to be, and throughout the books I’ve included questions, challenges and ‘Let’s talk’ activities to help them engage with the subject.
As the course closes, I’ve added a few words for students to take away. I talk about becoming scientifically literate – or as I put it in the workbooks, becoming ‘a scientific citizen’. I challenge them to explain everyday things with science, using a campfire scene as an example.
I explain that scientists have been driven to develop a theory of everything, and ask students to name ten scientists from the hundred-plus scientists featured throughout the books. In the final section, I look to the future where science and technology can work together to make a better world, finishing with a return to creativity – which has been a feature of scientific enquiry throughout the series.
There’s an end-of-course celebration suggested too, but you’ll have to look at the books to discover what that is!
Why This Approach Works
The Cambridge Checkpoint Science series builds scientific understanding systematically whilst maintaining student engagement through relevant, contemporary examples. Each stage develops both knowledge and scientific thinking skills, preparing students not just for examinations but for understanding the world around them.
