States of Matter: Why Are Tables Made from Solids? – KS3 Science
Engaging Lesson - Particle Model - Real-Life Application - New Activate Aligned

This fully resourced and interactive lesson explores states of matter through a relatable question: “Why is a table made from a solid and not a liquid or gas?”
Perfectly aligned with the New Activate KS3 Science Curriculum, this lesson brings particle theory to life through structured tasks, visual learning, and real-world context.

Learning Objectives:

Identify and describe the particle arrangement in solids, liquids, and gases

Understand the key properties of each state: shape, volume, and compressibility

Explain why solids are suitable for making objects like tables

Compare and contrast the usefulness of each state for structural purposes

Link particle attraction strength to state behaviour

Resource Features:

Fully editable PowerPoint lesson

Visual particle diagrams for annotation

Scaffolded questions and activities

Links scientific theory to real-world understanding

No printing required – ideal for digital display or remote delivery

Ideal For:
KS3 students (Years 7–9)
Teaching the Particle Model and States of Matter
