⚛️ Physics — Physical Quantities
A physical quantity is a measurable property expressed with a numerical value and a unit. Examples include length, mass, time and temperature.
Key idea: Measurements should be recorded with suitable units and appropriate precision.
🧪 Chemistry — Atoms, Elements & Compounds
An atom is the basic unit of an element. An element contains one type of atom. A compound contains two or more different elements chemically combined in a fixed ratio.
Valency: the combining capacity of an atom or ion, commonly related to electrons involved in bonding.
🌱 Biology — Enzymes
Enzymes are biological catalysts that speed up chemical reactions without being used up. Their activity is affected by factors such as temperature and pH.
Revision tip: Learn the enzyme, substrate, active site and effect of temperature/pH as connected ideas.
➗ Mathematics — Algebra
Like terms have the same variables raised to the same powers. To simplify an expression, combine the coefficients of like terms.
Example: 3x + 5x = 8x.
📖 English — Paragraph Writing
A strong paragraph usually has a clear topic sentence, supporting details and a concluding sentence. Keep ideas connected and use accurate grammar and punctuation.
