This resource bundle contains five PowerPoint lessons based on the AQA GCSE Combined Science Physics topic: Particle Model of Matter. Each lesson includes clear explanations, engaging visuals, real-world examples, and carefully structured activities. It is ideal for use in class, for revision, or for home learning.

The particle model of matter explains the behavior and properties of solids, liquids, and gases in terms of how particles are arranged and how they move. This model underpins key physical concepts like changes of state, density, pressure, and temperature, helping students understand phenomena such as floating and sinking, heating and cooling curves, and gas behavior under different conditions.

The bundle includes the following editable PowerPoint files:

Lesson 1: States of Matter – Introduces solids, liquids, and gases, including particle diagrams and particle arrangement.

Lesson 2: Changes of State – Covers melting, boiling, condensation, evaporation, freezing, sublimation, and includes explanations of heating/cooling curves and conservation of mass.

Lesson 3: Density – Explains what density is and how it’s calculated, using the density formula with examples and practice questions.

Lesson 4: Required Practical – Density – A full practical lesson with step-by-step methods for calculating the density of regular solids, irregular solids and liquids, using apparatus such as measuring cylinders and displacement cans.

Lesson 5: Gas Pressure and Temperature – Explores the relationship between temperature and pressure using the particle model, including Brownian motion and a pressure-temperature demonstration.
