Principles of Chemistry
Build from particles and states into mixtures, solubility and separation techniques.
A connected learning centre for CXC Chemistry, Biology and Physics — with syllabus-led lessons, practical skills, original CXC-style questions and structured revision pathways.
Start from the opening area of each CSEC syllabus. Each subject card shows your current lesson progress and gives quick access to lessons and the official syllabus.
Build from particles and states into mixtures, solubility and separation techniques.
Build from classification and sampling into abiotic factors, food webs and energy flow.
Build from scientific method and graphing into measurement, density and vectors.
Twelve full lessons now build the opening CSEC pathways. Use the filters or search to jump directly to what you need.
Particle arrangement, movement, energy and the properties of solids, liquids and gases.
Explain diffusion and phase change using particle ideas, then apply them to experimental evidence.
Recognise living characteristics, organise organisms and interpret classification evidence.
Investigate populations using quadrats and transects, with emphasis on fair sampling and data quality.
Use physical quantities, units, repeated measurements and experimental reasoning accurately.
Plan a pendulum investigation, process measurements and interpret relationships from graphs.
Classify mixtures and investigate solution types, colloids, suspensions and temperature effects on solubility.
Select filtration, distillation, chromatography and other methods from property differences, with Caribbean sugar context.
Master habitat, niche, population and community, then connect environmental factors to organism distribution.
Interpret trophic relationships, decomposers, predator–prey interactions and non-cyclic energy flow.
Choose appropriate instruments, manage error and determine density for solids and liquids.
Classify quantities, draw vectors to scale, calculate resultants and resolve vectors into components.

Every lesson blends factual knowledge with application and experimental thinking. Use these pathways to target the skill you need.
Build fast recall and interpretation using four-option CSEC-style items.
Practise MCQ →Use scientific language, explain relationships and show logical working.
Practise structured questions →Plan investigations, identify variables, analyse tables and graphs, and evaluate error.
Practise experimental skills →Keep the official CXC documents beside your lessons so you always know what the specification expects.
