**Bring the evolution of atomic theory to life in your classroom with this hands-on, interactive timeline task. **

Aligned with the NSW 2023 Science Syllabus, this activity guides students through the key historical models of the atom as they cut, match, and organise essential information to build their own visual timeline.

This resource includes key scientists, their discoveries, years, atomic diagrams, and portraits for students to research, match, and sequence correctly.

Covers the major contributors to atomic theory:

• Democritus
• John Dalton
• J.J. Thomson
• Ernest Rutherford
• Niels Bohr
• Erwin Schrödinger
• James Chadwick

Perfect for consolidating student understanding of how atomic theory has changed over time, this activity requires minimal preparation—simply print single-sided! Ideal for individual or group work, it’s great for research tasks, revision lessons, or collaborative classroom activities. Includes an answer key/exemplar timeline for easy marking or display.

A fun and effective way to reinforce the key milestones in the development of atomic theory!
