KS3 Science resources

Equip your students with the knowledge to excel in their own scientific investigations.

Aligned with the National Curriculum, our units are thoughtfully organised into separate courses, covering Biology, Chemistry and Physics. We begin with foundational units on cells, particles, and forces, and then progressively delve into intermediate and advanced units on interdependence, chemical reactions, circuits, the Periodic Table, forces and pressure, and photosynthesis and respiration.

Ignite a love for science with Access KS3 Science resources.

Why choose our KS3 Science resources?

Want to keep your students motivated and excited about science? Want to encourage them to explore, question, and experiment? Access KS3 Science resources are your trusted partner in nurturing inquisitive, scientifically literate, and critical-thinking students ready to shape the future through scientific exploration.

Fostering scientific imagination

At Access KS3, we believe in nurturing scientific curiosity and imagination. Our curriculum encourages students to explore the world of science from a variety of perspectives. We provide them with the tools to not only understand the core principles but also to embark on their own scientific inquiries.

A balanced approach to science

Our Key Stage 3 Science resources cover Biology, Chemistry, and Physics, ensuring that students receive a well-rounded education in the subject.

Beginning with foundational knowledge, we gradually build upon it with intermediate and advanced topics. This progressive approach prepares students for more complex scientific concepts and challenges.

Practical applications and scientific context

Science isn't just about theory; it's about practical application. We include examples of practical experiments in our lessons, allowing students to experience science in action.

Spotlights on scientists broaden students' knowledge of the subject and its real-world impact. We also provide opportunities to practice math skills in a scientific context, reinforcing the connection between science and mathematics.

Help your students on their journey to GCSE success with our KS3 Science resources
