Chemistry - KS5
Students at SJB study Chemistry to understand the substances that make up our world and the reactions that transform them. A Level Chemistry develops their ability to analyse, experiment, and explain the material changes around us—from the molecular to the industrial scale. It inspires them to think creatively and ethically about science’s role in society and equips them to contribute meaningfully to a sustainable and innovative future.
Qualification: GCE Chemistry OCR A (H432)
Exam Board: OCR
Course Specification Document
Chemistry is the science at the heart of some of the world’s most exciting and important careers. From creating new medicines as a pharmaceutical scientist, to developing sustainable fuels as a chemical engineer, to working in cutting-edge fields like nanotechnology, forensic analysis, or climate science—Chemistry opens the door. At A-level, our vision is to equip you with the knowledge, practical expertise, and problem-solving skills that employers and universities are looking for. By studying Chemistry, you’re not just preparing for exams; you’re preparing to shape the future in medicine, engineering, research, and beyond. Chemistry doesn’t just explain the world — it gives you the power to shape it
Modules:
1. Development of Practical Skills in Chemistry – You’ll spend plenty of time in the lab learning how to carry out experiments safely and accurately, analyse results, and evaluate methods — skills that are essential for both the exams and the practical endorsement.
2. Foundations in Chemistry – This module gives you the building blocks: atomic structure, bonding, moles, equations, and the mathematical principles that underpin the rest of the course.
3. Periodic Table and Energy – You’ll explore the patterns and reactivity of the elements, discover why chemical reactions release or absorb energy, and learn how these ideas link to real-world applications such as fuel efficiency and materials design.
4. Core Organic Chemistry – Carbon chemistry takes centre stage here, from hydrocarbons and alcohols to haloalkanes. You’ll study reaction mechanisms and functional groups that form the basis of medicines, polymers, and everyday chemicals.
5. Physical Chemistry and Transition Elements – This module develops your understanding of reaction rates, equilibria, acids and bases, and redox reactions, while also exploring the striking colours and catalytic powers of transition metals.
6. Organic Chemistry and Analysis – In your final module, you’ll study more complex molecules such as aromatic compounds, polymers, and amino acids, while mastering analytical tools like infrared (IR) spectroscopy, mass spectrometry, and nuclear magnetic resonance (NMR) to identify unknown compounds.
Practical Work
Regular lab sessions; students build a lab-book; practical skills are both taught and assessed. There is a Practical Endorsement (PAG's) which is reported separately but critical.
-
Strong understanding of chemical theory: atomic structure, bonding, organic reactions, thermodynamics, kinetics, etc.
-
Practical laboratory skills: safe handling of chemicals, accurate measurement, experimental design, data collection and analysis.
-
Mathematical skills: calculations in energetics, rates, equilibria, pH, etc.
-
Analytical and problem-solving skills: applying chemistry to unfamiliar cases, interpreting spectroscopy, working with quantitative data.
-
Transferable skills: precision, critical thinking, written and oral communication, scientific thinking.
-
Excellent preparation for STEM degrees (Chemistry, Biochemistry, Chemical Engineering, Medicine, Pharmacy, Materials Science etc.) and related careers.
Essential:
-
GCSE Grade 7 in Chemistry (or 7-7 in Combined Science if not doing separate sciences)
Desirable:
-
GCSE Grade 6 in Mathematics
-
Strong performance in relevant science topics (chemistry, physics, biology) at GCSE
-
Evidence of interest/skills in mathematics or work involving problem solving and quantitative reasoning
-
Good organisational skills and ability to work independently
Typical Profile of Successful Candidates:
Students who thrive are those who are curious about how things work at molecular and atomic levels; who enjoy practical experimentation; who don’t shy away from the mathematical aspects; who can sustain effort outside lessons for reading, problem practice, and revision.
